 # Security Policy
 ## How is Zoid secure?
 Zoid uses [Post Robot](https://github.com/krakenjs/post-robot) to do [post messaging](https://developer.mozilla.org/en-US/docs/Web/API/Window/postMessage) between multiple domains.
-Zoid helps secure messaging through iframe sanboxing, domain validation, and data protection.
+Zoid helps secure messaging through iframe sandboxing, domain validation, and data protection.
 - __Iframe sandboxing__ is a default browser feature that blocks others from accessing the data of your iframe instance. 
 - __Domain Validation__ checks the domain of the connection made to the Zoid child component, if requested. If domains don’t match accepted domains the connect fails. This is to stop access to secure components.
 - __Data Protection__ is the way Zoid manages checking domains of where the data was sent from to help protect against malicious data being injected through events.

+# Component
+
+## Instantiate `(props : { [string] : any }) => ZoidComponentInstance`
+
+Instantiate a component and pass in props.
+
+```javascript
+const Component = zoid.create({
+    tag: 'my-component',
+    url: 'https://my-site.com/my-component'
+});
+
+const componentInstance = Component({
+    foo: 'bar',
+    onSomething: () => {
+        console.log('Something happened!');
+    }
+});
+```
+
+See [Component Instance](./instance.md);
+
+## isChild `() => boolean`
+
+Returns `true` if the window you are currently in is an instance of the component, `false` if not.
+
+```javascript
+const MyComponent = zoid.create({ ... });
+
+if (MyComponent.isChild()) {
+    console.log('We are currently in a child iframe or popup of MyComponent!')
+}
+```
+
+## xprops `{ [string] : any }`
+
+Similar to `window.xprops` -- gives you access to the props passed down to the child window or iframe
+
+```javascript
+const MyComponent = zoid.create({ ... });
+
+console.log(MyComponent.xprops.message);
+```
+
+## canRenderTo `(Window) => Promise<boolean>`
+
+Returns a promise for a boolean, informing you if it is possible to remotely render the component to a different window.
+
+```javascript
+const MyComponent = zoid.create({ ... });
+
+MyComponent.canRenderTo(window.parent).then(result => {
+    if (result) {
+        console.log('We can render to the parent window!');
+        MyComponent().renderTo(window.parent, '#container');
+    }
+});
+```
+
+## Instances `Array<ZoidComponentInstances>`
+
+Provides an array of currently rendered instances of the zoid component
+
+```
+const MyComponent = zoid.create({ ... });
+
+console.log(`There are currently ${ MyComponent.instances.length } active instances of MyComponent`);
+```
+
+## driver `(frameworkName : string, dependencies : { ... }) => Driver`
+
+Register a component with your framework of choice, so it can be rendered natively in your app.
+
+```javascript
+import FooFramework from 'foo-framework';
+
+const Component = zoid.create({ ... });
+const FooComponent = Component.driver('foo', { FooFramework });
+
+// Now `FooComponent` is natively renderable inside a `FooFramework` app.
+```
+
+### React
+
+```javascript
+let MyReactZoidComponent = MyZoidComponent.driver('react', {
+    React:    React, 
+    ReactDOM: ReactDOM
+});
+```
+
+```javascript
+render() {
+    return (
+        <MyReactZoidComponent foo="bar" />
+    );
+}
+```
+
+### Angular 1
+
+```javascript
+MyZoidComponent.driver('angular', angular);`
+```
+

+
+```javascript
+// Create Vue application
+const app = Vue.createApp(...)
+
+// Define a new component called my-zoid 
+app.component('my-zoid', MyZoidComponent.driver('vue3'))

-##### Prop Options
-
-- **type** `string`
+See [Prop Definitions](./prop-definitions.md) for all options which can be passed to prop definitions.
 
-  The data-type expected for the prop
-
-  - `'string'`
-  - `'number'`
-  - `'boolean'`
-  - `'object'`
-  - `'function'`
-  - `'array'`
-
-- **required** `boolean`
-
-  Whether or not the prop is mandatory. Defaults to `true`.
-
-  ```javascript
-  onLogin: {
-      type: 'function',
-      required: false
-  }
-  ```
-
-- **default** `({ props }) => value`
-
-  A function returning the default value for the prop, if none is passed
-
-  ```javascript
-  email: {
-      type: 'string',
-      required: false,
-      default: function() {
-          return 'a@b.com';
-      }
-  }
-  ```
-
-- **validate** `({ value, props }) => void`
-
-  A function to validate the passed value. Should throw an appropriate error if invalid.
-
-  ```javascript
-  email: {
-      type: 'string',
-      validate: function({ value, props }) {
-          if (!value.match(/^.+@.+\..+$/)) {
-              throw new TypeError(`Expected email to be valid format`);
-          }
-      }
-  }
-  ```
-
-- **queryParam** `boolean | string | (value) => string`
-
-  Should a prop be passed in the url.
-
-  ```javascript
-  email: {
-      type: 'string',
-      queryParam: true // ?email=foo@bar.com
-  }
-  ```
-
-  If a string is set, this specifies the url param name which will be used. 
-
-  ```javascript
-  email: {
-      type: 'string',
-      queryParam: 'user-email' // ?user-email=foo@bar.com
-  }
-  ```
-
-  If a function is set, this is called to determine the url param which should be used.
-
-  ```javascript
-  email: {
-      type: 'string',
-      queryParam: function({ value }) {
-          if (value.indexOf('@foo.com') !== -1) {
-              return 'foo-email'; // ?foo-email=person@foo.com
-          } else {
-              return 'generic-email'; // ?generic-email=person@whatever.com
-          }
-      }
-  }
-  ```
-
-- **value** `({ props }) => value`
-
-  The value for the prop, if it should be statically defined at component creation time
-
-  ```javascript
-  userAgent: {
-      type: 'string',
-      value() {
-          return window.navigator.userAgent;
-      }
-  }
-  ```
-
-- **decorate** `({ value, props }) => value`
-
-  A function used to decorate the prop at render-time. Called with the value of the prop, should return the new value.
-
-  ```javascript
-  onLogin: {
-      type: 'function',
-      decorate(original) {
-          return function() {
-              console.log('User logged in!');
-              return original.apply(this, arguments);
-          };
-      }
-  }
-  ```
-
-- **serialization** `string`
-
-  If `json`, the prop will be JSON stringified before being inserted into the url
-
-  ```javascript
-  user: {
-      type: 'object',
-      serialization: 'json' // ?user={"name":"Zippy","age":34}
-  }
-  ```
-
-  If `dotify` the prop will be converted to dot-notation.
-
-  ```javascript
-  user: {
-      type: 'object',
-      serialization: 'dotify' // ?user.name=Zippy&user.age=34
-  }
-  ```
-
-  If `base64`, the prop will be JSON stringified then base64 encoded before being inserted into the url
-
-  ```javascript
-  user: {
-      type: 'object',
-      serialization: 'base64' // ?user=eyJuYW1lIjoiWmlwcHkiLCJhZ2UiOjM0fQ==
-  }
-  ```
-
-- **alias** `string`
-
-  An aliased name for the prop
-
-  ```javascript
-  onLogin: {
-      type: 'function',
-      alias: 'onUserLogin'
-  }
-  ```

-#### autoResize `{ height: boolean, width: boolean, element: string }`
+## autoResize `{ height: boolean, width: boolean, element: string }`
 
 Makes the iframe resize automatically when the child window size changes.
 
 ```javascript
-autoResize: {
-    width: false,
-    height: true,
-}
+const MyComponent = zoid.create({
+    tag: 'my-component',
+    url: 'https://my-site.com/my-component',
+    autoResize: {
+        width: false,
+        height: true,
+    }
+});
 ```
 
 Note that by default it matches the `body` element of your content.
 You can override this setting by specifying a custom selector as an `element` property.
 
 ```javascript
-autoResize: {
-    width: false,
-    height: true,
-    element: '.my-selector',
-}
+const MyComponent = zoid.create({
+    tag: 'my-component',

+        width: false,
+        height: true,
+        element: '.my-selector',
+    }
+});
 ```
 
 Recommended to only use autoResize for height. Width has some strange effects, especially when scroll bars are present.
 
-#### allowedParentDomains `string | Array<string | RegEx>`
+## allowedParentDomains `string | Array<string | RegEx>`
 
 A string, array of strings or reqular expresions to be used to validate parent domain. If parent domain doesn't match any item, communication from child to parent will be prevented. The default value is '*' which match any domain.
   
 ```javascript
-allowedParentDomains: [ 
-    "http://localhost",
-    /^http:\/\/www\.mydomain\.com$/
-  ]
+const MyComponent = zoid.create({
+    tag: 'my-component',

+    allowedParentDomains: [ 
+        "http://localhost",
+        /^http:\/\/www\.mydomain\.com$/
+    ]
+});
 ```
 
-#### domain `string`
+## domain `string`
 
 A string, or map of env to strings, for the domain which will be loaded in the iframe or popup.
 
 Only required if the domain which will be rendered is different to the domain specified in the `url` setting - for example, if the original url does a 302 redirect to a different domain or subdomain.
 
 ```javascript
-url: 'https://foo.com/login',
+const MyComponent = zoid.create({
+    tag: 'my-component',
+    url: 'https://foo.com/login',
+    domain: 'https://subdomain.foo.com'
+});
+
 
-domain: 'https://subdomain.foo.com'
 ```
 
-### defaultContext `string`
+## defaultContext `string`
 
 Determines which should be picked by default when `render()` is called. Defaults to `iframe`.
 
 ```javascript
-defaultContext: 'popup'
+const MyComponent = zoid.create({
+    tag: 'my-component',
+    url: 'https://my-site.com/my-component',

 Function which is passed all of the props at once and may validate them. Useful for validating inter-dependant props.
 
 ```javascript
-validate: function({ props }) {
-    if (props.name === 'Batman' && props.strength < 10) {
-        throw new Error(`Batman must have at least 10 strength`);
+const MyComponent = zoid.create({

-#### bridgeUrl `string | ({ props }) => string`
-
-The url or a function returning the url for a [post-robot bridge](https://github.com/krakenjs/post-robot#parent-to-popup-messaging). Will be automatically loaded in a hidden iframe when a popup component is rendered, to allow communication between the parent window and the popup in IE/Edge.
+## eligible `({ props : { [string] : any } }) => boolean`
 
-This is only necessary if you are creating a popup component which needs to run in IE and/or Edge.
+Function which determines if the component is eligible to be rendered.
 
 ```javascript
-bridgeUrl: 'https://foo.com/bridge'
+const FirefoxOnlyButton = zoid.create({
+    tag: 'my-component',
+    url: 'https://my-site.com/my-component',
+    eligible: () => {
+        if (isFireFox()) {
+            return true;
+        } else {
+            return false;
+        }
+    }
+})
 ```
 
+Now anyone can check eligibility prior to rendering the component:
+
 ```javascript
-bridgeUrl: ({ props }) => {
-    return (props.env === 'development')
-        ? 'http://foo.dev/bridge'
-        : 'https://foo.com/bridge';

+- container: can be a string selector like `'#my-container'` or a DOM element like `document.body`
+- context: defaults to `iframe` or `defaultContainer` if set. Can be overriden to explicitly specify `'iframe'` or `'popup'`.
+
+```javascript
+const component = MyComponent();
+
+component.render('#my-container').then(() => {
+    console.info('The component was successfully rendered')
+});
+```
+
+```javascript
+const component = MyComponent();
+
+component.render(document.body).then(() => {
+    console.info('The component was successfully rendered')
+});
+```
+
+```javascript
+const component = MyComponent();
+
+component.render('#my-container', 'popup').then(() => {
+    console.info('The component was successfully rendered')
+});
+```
+
+## renderTo `(window : Window, container : string | HTMLElement, context : 'iframe' | 'popup') => Promise<void>`
+
+Render the component to a given window and given container.
+
+- window: a reference to the window which the component should be rendered to. Zoid must be loaded in that window and the component must be registered.
+- container: must be a string selector like `'#my-container'` (DOM element is not transferable across different windows)
+- context: defaults to `iframe` or `defaultContainer` if set. Can be overriden to explicitly specify `'iframe'` or `'popup'`.
+
+```javascript
+const component = MyComponent();
+
+component.renderTo(window.parent, '#my-container').then(() => {
+    console.info('The component was successfully rendered')
+});
+```
+
+```javascript
+const component = MyComponent();
+
+component.renderTo(window.parent, '#my-container', 'popup').then(() => {
+    console.info('The component was successfully rendered')
+});
+```
+
+## clone `() => ZoidComponentInstance`
+
+Clones the current instance with the exact same set of props
+
+```javascript
+const button1 = ButtonComponent({
+    color: 'red'
+});
+
+const button2 = button1.clone();
+
+button1.render('#first-button-container'); // First red button
+button2.render('#first-button-container'); // Second red button
+```
+
+## isEligible `() => boolean`
+
+Informs if the component is eligible
+
+```javascript
+const myComponent = MyComponent();
+
+if (myComponent.isEligible()) {
+    myComponent.render('#my-container');
+}
+```
+
+To use `isEligible()` you must first define an `eligible` handler when setting up the component:
+
+```javascript
+const FirefoxOnlyButton = zoid.create({
+    tag: 'my-component',
+    url: 'https://my-site.com/my-component',
+    eligible: () => {
+        if (isFireFox()) {
+            return true;
+        } else {
+            return false;
+        }
+    }
+})
+```
+
+## close `() => Promise<void>`
+
+Gracefully close the component
+
+```javascript
+const myComponent = MyComponent();
+myComponent.render('#container');
+
+document.querySelector('button#close-component').addEventListener('click', () => {
+    myComponent.close().then(() => {
+        console.log('Component is now closed')
+    });
+});
+```
+
+## focus `() => Promise<void>`
+
+Focus the component. Only works for popup windows, on a user action like a click.
+
+```javascript
+const myComponent = MyComponent();
+myComponent.render('#container');
+
+document.querySelector('button#focus-component').addEventListener('click', () => {
+    myComponent.focus().then(() => {
+        console.log('Component is now focused')
+    });
+});
+```
+
+## resize `({ width : number, height : number }) => Promise<void>`
+
+Resize the component. Only works for iframe windows, popups can not be resized once opened.
+
+```javascript
+const myComponent = MyComponent();
+myComponent.render('#container');
+
+document.querySelector('button#resize-component').addEventListener('click', () => {
+    myComponent.resize({ width: 500, height: 800 }).then(() => {
+        console.log('Component is now resized')
+    });
+});
+```
+
+## show `() => Promise<void>`
+
+Show the component. Only works for iframe windows, popups can not be hidden/shown once opened.
+
+```javascript
+const myComponent = MyComponent();
+myComponent.render('#container');
+
+document.querySelector('button#show-component').addEventListener('click', () => {
+    myComponent.show().then(() => {
+        console.log('Component is now visible')
+    });
+});
+```
+
+## hide `() => Promise<void>`
+
+Hide the component. Only works for iframe windows, popups can not be hidden/shown once opened.
+
+```javascript
+const myComponent = MyComponent();
+myComponent.render('#container');
+
+document.querySelector('button#hide-component').addEventListener('click', () => {
+    myComponent.hide().then(() => {
+        console.log('Component is now hidden')
+    });
+});
+```
+
+## updateProps `({ [string ] : any }) => Promise<void>`
+
+Update props in the child window. The child can listen for new props using `window.xprops.onProps`
+
+In the parent window:
+
+```javascript
+const component = MyComponent({
+    color: 'red'
+});
+
+component.render('#container').then(() => {
+    component.setProps({
+        color: 'blue'
+    });
+});
+```
+
+In the child window:
+
+```javascript
+console.log('The current color is', window.xprops.color); // red
+
+window.xprops.onProps(() => {
+    console.log('The current color is', window.xprops.color); // lue
+});
+```
+
+## onError `(Error) => Promise<void>`
+
+Trigger an error in the component
+
+```javascript
+const myComponent = MyComponent();
+myComponent.render('#container');
+
+document.querySelector('button#trigger-error').addEventListener('click', () => {
+    myComponent.onError(new Error(`Something went wrong`)).then(() => {
+        console.log('Error successfully triggered')
+    });
+});
+```
+
+## event
+
+Event emitter that can be used to listen for the following events: `RENDER`, `RENDERED`, `DISPLAY`, `ERROR`, `CLOSED`, `PROPS`, `RESIZE`.
+
+```javascript
+const myComponent = MyComponent();
+myComponent.render('#container');
+
+myComponent.event.on(zoid.EVENT.RENDERED, () => {
+    console.log('Component was rendered!');
+});
+```
+
+## exports
+
+Any values defined in `export` and passed to `window.xprops.export()` will be available as keys on the component instance:
+
+```javascript
+const CreatePostForm = zoid.create({
+    tag: 'create-post-form',
+    url: 'https://my-site.com/component/create-post-form',
+
+    exports: ({ getExports }) => {
+        return {
+            submit: () => getExports().then(exports => exports.submit())
+        };
+    };
+});
+```
+
+Once this mapper is defined, the child window may export values up to the parent:
+
+```javascript
+window.xprops.export({
+    submit: () => {
+        document.querySelector('form#createPost').submit();
+    }
+});
+```
+
+The parent window may call these exports at any time:
+
+```javascript
+const postForm = CreatePostForm();
+postForm.render('#create-post-form-container');
+
+document.querySelector('button#submitForm').addEventListener('click', () => {
+    postForm.submit();
+});
+```

+# Prop Definitions
+
+## type
+
+`string`
+
+The data-type expected for the prop
+
+- `'string'`
+- `'number'`
+- `'boolean'`
+- `'object'`
+- `'function'`
+- `'array'`
+
+## required
+
+`boolean`
+
+Whether or not the prop is mandatory. Defaults to `true`.
+
+```javascript
+onLogin: {
+    type: 'function',
+    required: false
+}
+```
+
+## default
+
+```javascript
+({
+    props : Props,
+    state : Object,
+    close : () => Promise<undefined>,
+    focus : () => Promise<undefined>,
+    onError : (mixed) => Promise<undefined>,
+    container : HTMLElement | undefined,
+    event : Event
+}) => value
+```
+
+A function returning the default value for the prop, if none is passed
+
+```javascript
+email: {
+    type: 'string',
+    required: false,
+    default: function() {
+        return 'a@b.com';
+    }
+}
+```
+
+## validate
+
+`({ value, props }) => void`
+
+A function to validate the passed value. Should throw an appropriate error if invalid.
+
+```javascript
+email: {
+    type: 'string',
+    validate: function({ value, props }) {
+        if (!value.match(/^.+@.+\..+$/)) {
+            throw new TypeError(`Expected email to be valid format`);
+        }
+    }
+}
+```
+
+## queryParam
+
+`boolean | string | (value) => string`
+
+Should a prop be passed in the url.
+
+```javascript
+email: {
+    type: 'string',
+    queryParam: true // ?email=foo@bar.com
+}
+```
+
+If a string is set, this specifies the url param name which will be used. 
+
+```javascript
+email: {
+    type: 'string',
+    queryParam: 'user-email' // ?user-email=foo@bar.com
+}
+```
+
+If a function is set, this is called to determine the url param which should be used.
+
+```javascript
+email: {
+    type: 'string',
+    queryParam: function({ value }) {
+        if (value.indexOf('@foo.com') !== -1) {
+            return 'foo-email'; // ?foo-email=person@foo.com
+        } else {
+            return 'generic-email'; // ?generic-email=person@whatever.com
+        }
+    }
+}
+```
+
+## value
+
+```javascript
+({
+    props : Props,
+    state : Object,
+    close : () => Promise<undefined>,
+    focus : () => Promise<undefined>,
+    onError : (mixed) => Promise<undefined>,
+    container : HTMLElement | undefined,
+    event : Event
+}) => value
+```
+
+The value for the prop, if it should be statically defined at component creation time
+
+```javascript
+userAgent: {
+    type: 'string',
+    value() {
+        return window.navigator.userAgent;
+    }
+}
+```
+
+## decorate
+
+```javascript
+({
+    props : Props,
+    state : Object,
+    close : () => Promise<undefined>,
+    focus : () => Promise<undefined>,
+    onError : (mixed) => Promise<undefined>,
+    container : HTMLElement | undefined,
+    event : Event,
+    value : Value
+}) => value
+```
+
+A function used to decorate the prop at render-time. Called with the value of the prop, should return the new value.
+
+```javascript
+onLogin: {
+    type: 'function',
+    decorate(original) {
+        return function() {
+            console.log('User logged in!');
+            return original.apply(this, arguments);
+        };
+    }
+}
+```
+
+## serialization
+
+`string`
+
+If `json`, the prop will be JSON stringified before being inserted into the url
+
+```javascript
+user: {
+    type: 'object',
+    serialization: 'json' // ?user={"name":"Zippy","age":34}
+}
+```
+
+If `dotify` the prop will be converted to dot-notation.
+
+```javascript
+user: {
+    type: 'object',
+    serialization: 'dotify' // ?user.name=Zippy&user.age=34
+}
+```
+
+If `base64`, the prop will be JSON stringified then base64 encoded before being inserted into the url
+
+```javascript
+user: {
+    type: 'object',
+    serialization: 'base64' // ?user=eyJuYW1lIjoiWmlwcHkiLCJhZ2UiOjM0fQ==
+}
+```
+
+## alias
+
+`string`
+
+An aliased name for the prop
+
+```javascript
+onLogin: {
+    type: 'function',
+    alias: 'onUserLogin'
+}
+```

+# Render
+
+## Basic Render (same window)
+
+```javacript
+Component(props).render(container, ?context)
+```
+
+Render the component to the given container element.
+
+### props `{ [string] : any }`
+
+Object containing all of the props required by the given component. These can be user-defined props, or pre-defined built-in props.
+
+```javascript
+MyComponent({
+    foo: 'bar',
+    onBaz: () => {
+        console.log('Baz happened');
+    }
+}).render('#container');
+```
+
+See [Parent Props](./parent-props.md) for built-in props that can be passed to any zoid component.
+
+### container `string | HTMLElement`
+
+Element selector, or element, into which the component should be rendered.
+
+Defaults to `document.body`.
+
+### context `iframe | popup`
+
+The context to render to. Defaults to `defaultContext`, or if `defaultContext` is not set, `iframe`.
+
+## Remote render (different window)
+
+```javascript
+Component(props).renderTo(win, container, ?context)
+```
+
+Equivalent to `Component().render()` but allows rendering to a remote window. For example, a child component may render a new component to the parent page.
+
+- The component must have been registered on the target window
+- The component must be rendered from within the iframe of an existing component
+- The component being rendered must have the same domain as the component initiating the render
+
+### win `Window`
+
+The target window to which the component should be rendered. Ordinarily this will be `window.parent`.
+
+### props `{ [string] : any }`
+
+Object containing all of the props required by the given component
+
+### container `string`
+
+Element selector, into which the component should be rendered. Must be a string for remote rendering
+
+Defaults to `document.body`.
+
+### context `iframe | popup`
+
+The context to render to. Defaults to `defaultContext`, or if `defaultContext` is not set, `iframe`.

+# `xprops`
+
+By default `window.xprops` is populated in the child window/frame with any props from the parent.
+
+Some built-in props are provided and automatically populated on `window.xprops`:
+
+## xprops.close `() => Promise<void>`
+
+Gracefully close the component.
+
+```javascript
+document.querySelector('button#close').addEventListener('click', () => {
+    window.xprops.close();
+});
+```
+
+## xprops.focus `() => Promise<void>`
+
+Refocus the component. Works on popup windows only, should be triggered on a user interaction like a click, in order to be allowed by the browser.
+
+```javascript
+document.querySelector('button#focus').addEventListener('click', () => {
+    window.xprops.focus();
+});
+```
+
+## xprops.resize `({ width : number, height : number }) => Promise<void>`
+
+Resize the component. Works on iframe windows only, popups can not be resized after opening.
+
+```javascript
+document.querySelector('button#resize').addEventListener('click', () => {
+    window.xprops.resize({ width: 500, height: 800 });
+});
+```
+
+## xprops.uid `string`
+
+Unique ID for the component instance
+
+```javascript
+console.log('The current component uid is:', window.xprops.uid);
+```
+
+## xprops.tag `string`
+
+Tag for the component instance
+
+```javascript
+console.log('The current component is:', window.xprops.tag);
+```
+
+## xprops.getParent `() => Window`
+
+Get a reference to the parent window
+
+```javascript
+const parentWindow = window.xprops.getParent();
+
+parentWindow.postMessage('hello!', '*');
+```
+
+## xprops.getParentDomain `() => string`
+
+Get the domain of the parent window
+
+```javascript
+console.log('The current parent window domain is:', window.xprops.getParentDomain());
+```
+
+## xprops.show `() => Promise<void>`
+
+Show the component. Works on iframe windows only, popups can not be shown/hidden after opening.
+
+```javascript
+document.querySelector('button#show').addEventListener('click', () => {
+    window.xprops.show();
+});
+```
+
+## xprops.hide `() => Promise<void>`
+
+Hide the component. Works on iframe windows only, popups can not be shown/hidden after opening.
+
+```javascript
+document.querySelector('button#hide').addEventListener('click', () => {
+    window.xprops.hide();
+});
+```
+
+## xprops.export `({ [string] : any }) => Promise<void>`
+
+Export data and/or functions from the child to the parent window.
+
+```javascript
+window.xprops.export({
+    submit: () => {
+        document.querySelector('form#createPost').submit();
+    }
+});
+```
+
+This export will be available on the parent window:
+
+```javascript
+const postForm = CreatePostForm();
+postForm.render('#create-post-form-container');
+
+document.querySelector('button#submitForm').addEventListener('click', () => {
+    postForm.submit();
+});
+```
+
+This assumes that when the component was first created, the author implemented the `exports` function to ensure the exports are mapped to the parent:
+
+```javascript
+const CreatePostForm = zoid.create({
+    tag: 'create-post-form',
+    url: 'https://my-site.com/component/create-post-form',
+
+    exports: ({ getExports }) => {
+        return {
+            submit: () => getExports().then(exports => exports.submit())
+        };
+    };
+});
+```
+
+This mapper is necessary so that the exports are immediately available on the parent component instance, even before the component is fully rendered and before `xprops.export(...)` has been called in the child window.
+
+## xprops.onError `(Error) => Promise<void>`
+
+Send an error to the parent
+
+```
+window.xprops.onError(new Error(`Something went wrong!`));
+```
+
+## xprops.onProps `(({ [string] : any }) => void) => void`
+
+Set up a listener to receive new props as they are set by the parent window using `componentInstance.setProps(...)`
+
+In the child window:
+
+```javascript
+console.log('The current color is', window.xprops.color); // red
+
+window.xprops.onProps(() => {
+    console.log('The current color is', window.xprops.color); // lue
+});
+```
+
+In the parent window:
+
+```javascript
+const component = MyComponent({
+    color: 'red'
+});
+
+component.render('#container').then(() => {
+    component.setProps({
+        color: 'blue'
+    });
+});
+```
+
+## xprops.parent.props `{ [string] : any }`
+
+Props from the parent component, if the component is rendered as a child.
+
+Define the components:
+
+```javascript
+const ChildComponent = zoid.create({
+    tag: 'child-component',
+    url: 'https://my-site.com/component/child'
+});
+
+const ParentComponent = zoid.create({
+    tag: 'child-component',
+    url: 'https://my-site.com/component/child',

+    children: () => {
+        return {
+            Child: ChildComponent
+        }
+    }
+});
+```
+
+In the parent window:
+
+```javascript
+const parent = ParentComponent({
+    color: 'blue'
+});
+
+const child = parent.Child();
+
+child.render('#child-container');
+```
+
+In the child window:
+
+```javascript
+console.log('The color of this component is:', window.xprops.parent.color); // Red
+```
+
+## xprops.parent.export `({ [string] : any }) => Promise<void>`
+
+Export values to the parent component.

+     * ### Fine tune control
+     *
+     * You can control the component creation process by using the following optional attributes:
+     *
+     * * `ngComponentOutletInjector`: Optional custom {@link Injector} that will be used as parent for
+     * the Component. Defaults to the injector of the current view container.
+     *

+     * section of the component, if exists.
+     *
+     * * `ngComponentOutletNgModuleFactory`: Optional module factory to allow dynamically loading other
+     * module, then load a component from that module.
+     *
+     * ### Syntax
+     *
+     * Simple
+     * ```
+     * <ng-container *ngComponentOutlet="componentTypeExpression"></ng-container>
+     * ```
+     *
+     * Customized injector/content
+     * ```
+     * <ng-container *ngComponentOutlet="componentTypeExpression;
+     *                                   injector: injectorExpression;
+     *                                   content: contentNodesExpression;">
+     * </ng-container>
+     * ```
+     *
+     * Customized ngModuleFactory
+     * ```

+     * A [structural directive](guide/structural-directives) that renders
+     * a template for each item in a collection.
+     * The directive is placed on an element, which becomes the parent
+     * of the cloned templates.
+     *
+     * The `ngForOf` directive is generally used in the
+     * [shorthand form](guide/structural-directives#asterisk) `*ngFor`.
+     * In this form, the template to be rendered for each iteration is the content
+     * of an anchor element containing the directive.
+     *
+     * The following example shows the shorthand syntax with some options,
+     * contained in an `<li>` element.
+     *
+     * ```
+     * <li *ngFor="let item of items; index as i; trackBy: trackByFn">...</li>
+     * ```
+     *
+     * The shorthand form expands into a long form that uses the `ngForOf` selector
+     * on an `<ng-template>` element.
+     * The content of the `<ng-template>` element is the `<li>` element that held the
+     * short-form directive.
+     *
+     * Here is the expanded version of the short-form example.
+     *
+     * ```
+     * <ng-template ngFor let-item [ngForOf]="items" let-i="index" [ngForTrackBy]="trackByFn">
+     *   <li>...</li>
+     * </ng-template>
+     * ```
+     *
+     * Angular automatically expands the shorthand syntax as it compiles the template.
+     * The context for each embedded view is logically merged to the current component
+     * context according to its lexical position.
+     *
+     * When using the shorthand syntax, Angular allows only [one structural directive
+     * on an element](guide/built-in-directives#one-per-element).
+     * If you want to iterate conditionally, for example,
+     * put the `*ngIf` on a container element that wraps the `*ngFor` element.
+     * For futher discussion, see
+     * [Structural Directives](guide/built-in-directives#one-per-element).
+     *
+     * @usageNotes
+     *
+     * ### Local variables
+     *
+     * `NgForOf` provides exported values that can be aliased to local variables.
+     * For example:
+     *
+     *  ```
+     * <li *ngFor="let user of users; index as i; first as isFirst">
+     *    {{i}}/{{users.length}}. {{user}} <span *ngIf="isFirst">default</span>
+     * </li>
+     * ```
+     *
+     * The following exported values can be aliased to local variables:
+     *
+     * - `$implicit: T`: The value of the individual items in the iterable (`ngForOf`).
+     * - `ngForOf: NgIterable<T>`: The value of the iterable expression. Useful when the expression is
+     * more complex then a property access, for example when using the async pipe (`userStreams |
+     * async`).
+     * - `index: number`: The index of the current item in the iterable.
+     * - `count: number`: The length of the iterable.
+     * - `first: boolean`: True when the item is the first item in the iterable.
+     * - `last: boolean`: True when the item is the last item in the iterable.
+     * - `even: boolean`: True when the item has an even index in the iterable.
+     * - `odd: boolean`: True when the item has an odd index in the iterable.
+     *
+     * ### Change propagation
+     *
+     * When the contents of the iterator changes, `NgForOf` makes the corresponding changes to the DOM:
+     *
+     * * When an item is added, a new instance of the template is added to the DOM.
+     * * When an item is removed, its template instance is removed from the DOM.
+     * * When items are reordered, their respective templates are reordered in the DOM.
+     *
+     * Angular uses object identity to track insertions and deletions within the iterator and reproduce
+     * those changes in the DOM. This has important implications for animations and any stateful
+     * controls that are present, such as `<input>` elements that accept user input. Inserted rows can
+     * be animated in, deleted rows can be animated out, and unchanged rows retain any unsaved state
+     * such as user input.
+     * For more on animations, see [Transitions and Triggers](guide/transition-and-triggers).
+     *
+     * The identities of elements in the iterator can change while the data does not.
+     * This can happen, for example, if the iterator is produced from an RPC to the server, and that
+     * RPC is re-run. Even if the data hasn't changed, the second response produces objects with
+     * different identities, and Angular must tear down the entire DOM and rebuild it (as if all old
+     * elements were deleted and all new elements inserted).
+     *
+     * To avoid this expensive operation, you can customize the default tracking algorithm.
+     * by supplying the `trackBy` option to `NgForOf`.
+     * `trackBy` takes a function that has two arguments: `index` and `item`.
+     * If `trackBy` is given, Angular tracks changes by the return value of the function.

+     * ```
+     *
+     * @usageNotes
+     *
+     * The `*ngIf` directive is most commonly used to conditionally show an inline template,
+     * as seen in the following  example.
+     * The default `else` template is blank.
+     *
+     * {@example common/ngIf/ts/module.ts region='NgIfSimple'}
+     *
+     * ### Showing an alternative template using `else`
+     *
+     * To display a template when `expression` evaluates to false, use an `else` template
+     * binding as shown in the following example.
+     * The `else` binding points to an `<ng-template>`  element labeled `#elseBlock`.
+     * The template can be defined anywhere in the component view, but is typically placed right after
+     * `ngIf` for readability.
+     *
+     * {@example common/ngIf/ts/module.ts region='NgIfElse'}
+     *
+     * ### Using an external `then` template
+     *
+     * In the previous example, the then-clause template is specified inline, as the content of the
+     * tag that contains the `ngIf` directive. You can also specify a template that is defined
+     * externally, by referencing a labeled `<ng-template>` element. When you do this, you can
+     * change which template to use at runtime, as shown in the following example.
+     *
+     * {@example common/ngIf/ts/module.ts region='NgIfThenElse'}
+     *
+     * ### Storing a conditional result in a variable
+     *
+     * You might want to show a set of properties from the same object. If you are waiting
+     * for asynchronous data, the object can be undefined.
+     * In this case, you can use `ngIf` and store the result of the condition in a local
+     * variable as shown in the following example.
+     *
+     * {@example common/ngIf/ts/module.ts region='NgIfAs'}
+     *
+     * This code uses only one `AsyncPipe`, so only one subscription is created.
+     * The conditional statement stores the result of `userStream|async` in the local variable `user`.
+     * You can then bind the local `user` repeatedly.
+     *
+     * The conditional displays the data only if `userStream` returns a value,
+     * so you don't need to use the
+     * safe-navigation-operator (`?.`)
+     * to guard against null values when accessing properties.
+     * You can display an alternative template while waiting for the data.
+     *
+     * ### Shorthand syntax
+     *
+     * The shorthand syntax `*ngIf` expands into two separate template specifications
+     * for the "then" and "else" clauses. For example, consider the following shorthand statement,
+     * that is meant to show a loading page while waiting for data to be loaded.
+     *
+     * ```
+     * <div class="hero-list" *ngIf="heroes else loading">
+     *  ...
+     * </div>
+     *
+     * <ng-template #loading>
+     *  <div>Loading...</div>
+     * </ng-template>
+     * ```
+     *
+     * You can see that the "else" clause references the `<ng-template>`
+     * with the `#loading` label, and the template for the "then" clause
+     * is provided as the content of the anchor element.
+     *
+     * However, when Angular expands the shorthand syntax, it creates
+     * another `<ng-template>` tag, with `ngIf` and `ngIfElse` directives.
+     * The anchor element containing the template for the "then" clause becomes
+     * the content of this unlabeled `<ng-template>` tag.
+     *
+     * ```
+     * <ng-template [ngIf]="heroes" [ngIfElse]="loading">
+     *  <div class="hero-list">
+     *   ...
+     *  </div>
+     * </ng-template>
+     *
+     * <ng-template #loading>
+     *  <div>Loading...</div>
+     * </ng-template>
+     * ```
+     *
+     * The presence of the implicit template object has implications for the nesting of
+     * structural directives. For more on this subject, see
+     * [Structural Directives](https://angular.io/guide/built-in-directives#one-per-element).

+     * @description
+     * The `[ngSwitch]` directive on a container specifies an expression to match against.
+     * The expressions to match are provided by `ngSwitchCase` directives on views within the container.
+     * - Every view that matches is rendered.
+     * - If there are no matches, a view with the `ngSwitchDefault` directive is rendered.
+     * - Elements within the `[NgSwitch]` statement but outside of any `NgSwitchCase`
+     * or `ngSwitchDefault` directive are preserved at the location.
+     *
+     * @usageNotes
+     * Define a container element for the directive, and specify the switch expression
+     * to match against as an attribute:
+     *
+     * ```
+     * <container-element [ngSwitch]="switch_expression">
+     * ```
+     *
+     * Within the container, `*ngSwitchCase` statements specify the match expressions
+     * as attributes. Include `*ngSwitchDefault` as the final case.
+     *
+     * ```
+     * <container-element [ngSwitch]="switch_expression">
+     *    <some-element *ngSwitchCase="match_expression_1">...</some-element>
+     * ...
+     *    <some-element *ngSwitchDefault>...</some-element>
+     * </container-element>
+     * ```
+     *
+     * ### Usage Examples
+     *
+     * The following example shows how to use more than one case to display the same view:
+     *
+     * ```
+     * <container-element [ngSwitch]="switch_expression">
+     *   <!-- the same view can be shown in more than one case -->
+     *   <some-element *ngSwitchCase="match_expression_1">...</some-element>
+     *   <some-element *ngSwitchCase="match_expression_2">...</some-element>
+     *   <some-other-element *ngSwitchCase="match_expression_3">...</some-other-element>
+     *   <!--default case when there are no matches -->
+     *   <some-element *ngSwitchDefault>...</some-element>
+     * </container-element>
+     * ```
+     *
+     * The following example shows how cases can be nested:
+     * ```
+     * <container-element [ngSwitch]="switch_expression">
+     *       <some-element *ngSwitchCase="match_expression_1">...</some-element>
+     *       <some-element *ngSwitchCase="match_expression_2">...</some-element>
+     *       <some-other-element *ngSwitchCase="match_expression_3">...</some-other-element>
+     *       <ng-container *ngSwitchCase="match_expression_3">
+     *         <!-- use a ng-container to group multiple root nodes -->
+     *         <inner-element></inner-element>
+     *         <inner-other-element></inner-other-element>

+     *
+     * Formats a date value according to locale rules.
+     *
+     * `DatePipe` is executed only when it detects a pure change to the input value.
+     * A pure change is either a change to a primitive input value
+     * (such as `String`, `Number`, `Boolean`, or `Symbol`),
+     * or a changed object reference (such as `Date`, `Array`, `Function`, or `Object`).
+     *
+     * Note that mutating a `Date` object does not cause the pipe to be rendered again.
+     * To ensure that the pipe is executed, you must create a new `Date` object.
+     *
+     * Only the `en-US` locale data comes with Angular. To localize dates
+     * in another language, you must import the corresponding locale data.
+     * See the [I18n guide](guide/i18n#i18n-pipes) for more information.
+     *
+     * @see `formatDate()`
+     *
+     *
+     * @usageNotes
+     *
+     * The result of this pipe is not reevaluated when the input is mutated. To avoid the need to
+     * reformat the date on every change-detection cycle, treat the date as an immutable object
+     * and change the reference when the pipe needs to run again.
+     *
+     * ### Pre-defined format options

+     * ### Format examples
+     *
+     * These examples transform a date into various formats,
+     * assuming that `dateObj` is a JavaScript `Date` object for
+     * year: 2015, month: 6, day: 15, hour: 21, minute: 43, second: 11,
+     * given in the local time for the `en-US` locale.
+     *
+     * ```
+     * {{ dateObj | date }}               // output is 'Jun 15, 2015'
+     * {{ dateObj | date:'medium' }}      // output is 'Jun 15, 2015, 9:43:11 PM'
+     * {{ dateObj | date:'shortTime' }}   // output is '9:43 PM'
+     * {{ dateObj | date:'mm:ss' }}       // output is '43:11'
+     * ```
+     *
+     * ### Usage example
+     *
+     * The following component uses a date pipe to display the current date in different formats.
+     *
+     * ```
+     * @Component({
+     *  selector: 'date-pipe',
+     *  template: `<div>
+     *    <p>Today is {{today | date}}</p>
+     *    <p>Or if you prefer, {{today | date:'fullDate'}}</p>
+     *    <p>The time is {{today | date:'h:mm a z'}}</p>
+     *  </div>`
+     * })
+     * // Get the current date and time as a date-time value.
+     * export class DatePipeComponent {
+     *   today: number = Date.now();
+     * }
+     * ```

+      discussion of the approach used to shim.
+
+      Shimmed features:
+
+      * :host, :host-context: ShadowDOM allows styling of the shadowRoot's host
+      element using the :host rule. To shim this feature, the :host styles are
+      reformatted and prefixed with a given scope name and promoted to a
+      document level stylesheet.
+      For example, given a scope name of .foo, a rule like this:
+
+        :host {
+            background: red;
+          }
+        }
+
+      becomes:
+
+        .foo {
+          background: red;
+        }
+
+      * encapsulation: Styles defined within ShadowDOM, apply only to
+      dom inside the ShadowDOM. Polymer uses one of two techniques to implement
+      this feature.
+
+      By default, rules are prefixed with the host element tag name
+      as a descendant selector. This ensures styling does not leak out of the 'top'
+      of the element's ShadowDOM. For example,
+
+      div {
+          font-weight: bold;
+        }
+
+      becomes:
+
+      x-foo div {
+          font-weight: bold;
+        }
+
+      becomes:
+
+
+      Alternatively, if WebComponents.ShadowCSS.strictStyling is set to true then
+      selectors are scoped by adding an attribute selector suffix to each
+      simple selector that contains the host element tag name. Each element
+      in the element's ShadowDOM template is also given the scope attribute.
+      Thus, these rules match only elements that have the scope attribute.
+      For example, given a scope name of x-foo, a rule like this:
+
+        div {
+          font-weight: bold;
+        }
+
+      becomes:
+
+        div[x-foo] {
+          font-weight: bold;
+        }
+
+      Note that elements that are dynamically added to a scope must have the scope
+      selector added to them manually.
+
+      * upper/lower bound encapsulation: Styles which are defined outside a
+      shadowRoot should not cross the ShadowDOM boundary and should not apply
+      inside a shadowRoot.
+
+      This styling behavior is not emulated. Some possible ways to do this that
+      were rejected due to complexity and/or performance concerns include: (1) reset
+      every possible property for every possible selector for a given scope name;
+      (2) re-implement css in javascript.
+
+      As an alternative, users should make sure to use selectors
+      specific to the scope in which they are working.
+
+      * ::distributed: This behavior is not emulated. It's often not necessary
+      to style the contents of a specific insertion point and instead, descendants
+      of the host element can be styled selectively. Users can also create an
+      extra node around an insertion point and style that node's contents
+      via descendent selectors. For example, with a shadowRoot like this:
+
+        <style>
+          ::content(div) {
+            background: red;
+          }
+        </style>
+        <content></content>
+
+      could become:
+
+        <style>
+          / *@polyfill .content-container div * /
+          ::content(div) {
+            background: red;
+          }
+        </style>
+        <div class="content-container">
+          <content></content>
+        </div>
+
+      Note the use of @polyfill in the comment above a ShadowDOM specific style
+      declaration. This is a directive to the styling shim to use the selector
+      in comments in lieu of the next selector when running under polyfill.

+     * This array represents the DOM schema. It encodes inheritance, properties, and events.
+     *
+     * ## Overview
+     *
+     * Each line represents one kind of element. The `element_inheritance` and properties are joined
+     * using `element_inheritance|properties` syntax.
+     *
+     * ## Element Inheritance
+     *
+     * The `element_inheritance` can be further subdivided as `element1,element2,...^parentElement`.
+     * Here the individual elements are separated by `,` (commas). Every element in the list
+     * has identical properties.
+     *
+     * An `element` may inherit additional properties from `parentElement` If no `^parentElement` is
+     * specified then `""` (blank) element is assumed.
+     *
+     * NOTE: The blank element inherits from root `[Element]` element, the super element of all
+     * elements.
+     *
+     * NOTE an element prefix such as `:svg:` has no special meaning to the schema.
+     *
+     * ## Properties
+     *
+     * Each element has a set of properties separated by `,` (commas). Each property can be prefixed
+     * by a special character designating its type:
+     *
+     * - (no prefix): property is a string.
+     * - `*`: property represents an event.
+     * - `!`: property is a boolean.
+     * - `#`: property is a number.
+     * - `%`: property is an object.
+     *
+     * ## Query
+     *
+     * The class creates an internal squas representation which allows to easily answer the query of
+     * if a given property exist on a given element.
+     *
+     * NOTE: We don't yet support querying for types or events.
+     * NOTE: This schema is auto extracted from `schema_extractor.ts` located in the test folder,
+     *       see dom_element_schema_registry_spec.ts

+         *
+         * ```
+         * attrs = [prop, value, prop2, value2,

+     * commonplace to use a regular expression for parsing the potential five

+     *
+     * The following line is the regular expression for breaking-down a
+     * well-formed URI reference into its components.

+     * <pre>
+     * ^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))?

+     * </pre>
+     *
+     * The numbers in the second line above are only to assist readability; they
+     * indicate the reference points for each subexpression (i.e., each paired
+     * parenthesis). We refer to the value matched for subexpression <n> as $<n>.
+     * For example, matching the above expression to
+     * <pre>
+     *     http://www.ics.uci.edu/pub/ietf/uri/#Related
+     * </pre>
+     * results in the following subexpression matches:

+     * </pre>
+     * where <undefined> indicates that the component is not present, as is the

+     * determine the value of the five components as
+     * <pre>

+     * Creates a token that can be used in a DI Provider.

+     * Use an `InjectionToken` whenever the type you are injecting is not reified (does not have a
+     * runtime representation) such as when injecting an interface, callable type, array or
+     * parameterized type.
+     *
+     * `InjectionToken` is parameterized on `T` which is the type of object which will be returned by
+     * the `Injector`. This provides additional level of type safety.
+     *
+     * ```
+     * interface MyInterface {...}
+     * var myInterface = injector.get(new InjectionToken<MyInterface>('SomeToken'));
+     * // myInterface is inferred to be MyInterface.
+     * ```
+     *
+     * When creating an `InjectionToken`, you can optionally specify a factory function which returns
+     * (possibly by creating) a default value of the parameterized type `T`. This sets up the
+     * `InjectionToken` using this factory as a provider as if it was defined explicitly in the
+     * application's root injector. If the factory function, which takes zero arguments, needs to inject
+     * dependencies, it can do so using the `inject` function. See below for an example.
+     *
+     * Additionally, if a `factory` is specified you can also specify the `providedIn` option, which
+     * overrides the above behavior and marks the token as belonging to a particular `@NgModule`. As
+     * mentioned above, `'root'` is the default value for `providedIn`.

+     * A ReflectiveDependency injection container used for instantiating objects and resolving
+     * dependencies.
+     *
+     * An `Injector` is a replacement for a `new` operator, which can automatically resolve the
+     * constructor dependencies.
+     *
+     * In typical use, application code asks for the dependencies in the constructor and they are
+     * resolved by the `Injector`.
+     *
+     * @usageNotes
+     * ### Example
+     *
+     * The following example creates an `Injector` configured to create `Engine` and `Car`.
+     *
+     * ```typescript
+     * @Injectable()
+     * class Engine {
+     * }
+     *
+     * @Injectable()
+     * class Car {

+     * var injector = ReflectiveInjector.resolveAndCreate([Car, Engine]);
+     * var car = injector.get(Car);
+     * expect(car instanceof Car).toBe(true);
+     * expect(car.engine instanceof Engine).toBe(true);
+     * ```
+     *
+     * Notice, we don't use the `new` operator because we explicitly want to have the `Injector`
+     * resolve all of the object's dependencies automatically.
+     *
+     * @deprecated from v5 - slow and brings in a lot of code, Use `Injector.create` instead.

+     * To improve performance, we want to check and update the list
+     * less often than the changes actually occur. To do that, we detach

+    // called during a pre-order traversal of the view tree (that is calling the
+    // parent hooks before the child hooks) these events are sent in using a
+    // post-order traversal of the tree (children before parents). This changes the
+    // meaning of initIndex in the view state. For ngOnInit, initIndex tracks the
+    // expected nodeIndex which a ngOnInit should be called. When sending
+    // ngAfterContentInit and ngAfterViewInit it is the expected count of
+    // ngAfterContentInit or ngAfterViewInit methods that have been called. This
+    // ensure that despite being called recursively or after picking up after an
+    // exception, the ngAfterContentInit or ngAfterViewInit will be called on the
+    // correct nodes. Consider for example, the following (where E is an element
+    // and D is a directive)
+    //  Tree:       pre-order index  post-order index
+    //    E1        0                6
+    //      E2      1                1
+    //       D3     2                0
+    //      E4      3                5
+    //       E5     4                4
+    //        E6    5                2
+    //        E7    6                3
+    // As can be seen, the post-order index has an unclear relationship to the
+    // pre-order index (postOrderIndex === preOrderIndex - parentCount +
+    // childCount). Since number of calls to ngAfterContentInit and ngAfterViewInit
+    // are stable (will be the same for the same view regardless of exceptions or
+    // recursion) we just need to count them which will roughly correspond to the
+    // post-order index (it skips elements and directives that do not have
+    // lifecycle hooks).
+    //
+    // For example, if an exception is raised in the E6.onAfterViewInit() the
+    // initIndex is left at 3 (by shouldCallLifecycleInitHook() which set it to
+    // initIndex + 1). When checkAndUpdateView() is called again D3, E2 and E6 will
+    // not have their ngAfterViewInit() called but, starting with E7, the rest of
+    // the view will begin getting ngAfterViewInit() called until a check and
+    // pass is complete.
+    //
+    // This algorthim also handles recursion. Consider if E4's ngAfterViewInit()
+    // indirectly calls E1's ChangeDetectorRef.detectChanges(). The expected
+    // initIndex is set to 6, the recusive checkAndUpdateView() starts walk again.
+    // D3, E2, E6, E7, E5 and E4 are skipped, ngAfterViewInit() is called on E1.
+    // When the recursion returns the initIndex will be 7 so E1 is skipped as it
+    // has already been called in the recursively called checkAnUpdateView().

+     * {@a is-stable-examples}
+     * ### isStable examples and caveats
+     *
+     * Note two important points about `isStable`, demonstrated in the examples below:
+     * - the application will never be stable if you start any kind
+     * of recurrent asynchronous task when the application starts
+     * (for example for a polling process, started with a `setInterval`, a `setTimeout`
+     * or using RxJS operators like `interval`);
+     * - the `isStable` Observable runs outside of the Angular zone.
+     *
+     * Let's imagine that you start a recurrent task
+     * (here incrementing a counter, using RxJS `interval`),
+     * and at the same time subscribe to `isStable`.
+     *
+     * ```
+     * constructor(appRef: ApplicationRef) {
+     *   appRef.isStable.pipe(
+     *      filter(stable => stable)
+     *   ).subscribe(() => console.log('App is stable now');
+     *   interval(1000).subscribe(counter => console.log(counter));
+     * }
+     * ```
+     * In this example, `isStable` will never emit `true`,
+     * and the trace "App is stable now" will never get logged.
+     *
+     * If you want to execute something when the app is stable,
+     * you have to wait for the application to be stable
+     * before starting your polling process.
+     *
+     * ```
+     * constructor(appRef: ApplicationRef) {
+     *   appRef.isStable.pipe(
+     *     first(stable => stable),
+     *     tap(stable => console.log('App is stable now')),
+     *     switchMap(() => interval(1000))
+     *   ).subscribe(counter => console.log(counter));
+     * }
+     * ```
+     * In this example, the trace "App is stable now" will be logged
+     * and then the counter starts incrementing every second.
+     *
+     * Note also that this Observable runs outside of the Angular zone,
+     * which means that the code in the subscription
+     * to this Observable will not trigger the change detection.
+     *
+     * Let's imagine that instead of logging the counter value,
+     * you update a field of your component
+     * and display it in its template.
+     *
+     * ```
+     * constructor(appRef: ApplicationRef) {
+     *   appRef.isStable.pipe(
+     *     first(stable => stable),
+     *     switchMap(() => interval(1000))
+     *   ).subscribe(counter => this.value = counter);
+     * }
+     * ```
+     * As the `isStable` Observable runs outside the zone,
+     * the `value` field will be updated properly,
+     * but the template will not be refreshed!
+     *
+     * You'll have to manually trigger the change detection to update the template.
+     *
+     * ```
+     * constructor(appRef: ApplicationRef, cd: ChangeDetectorRef) {
+     *   appRef.isStable.pipe(
+     *     first(stable => stable),
+     *     switchMap(() => interval(1000))
+     *   ).subscribe(counter => {
+     *     this.value = counter;
+     *     cd.detectChanges();
+     *   });
+     * }
+     * ```
+     *
+     * Or make the subscription callback run inside the zone.
+     *
+     * ```
+     * constructor(appRef: ApplicationRef, zone: NgZone) {
+     *   appRef.isStable.pipe(
+     *     first(stable => stable),

+         * Bootstrap a component onto the element identified by its selector or, optionally, to a
+         * specified element.
+         *
+         * @usageNotes
+         * ### Bootstrap process
+         *
+         * When bootstrapping a component, Angular mounts it onto a target DOM element
+         * and kicks off automatic change detection. The target DOM element can be
+         * provided using the `rootSelectorOrNode` argument.
+         *
+         * If the target DOM element is not provided, Angular tries to find one on a page
+         * using the `selector` of the component that is being bootstrapped
+         * (first matched element is used).
+         *
+         * ### Example
+         *
+         * Generally, we define the component to bootstrap in the `bootstrap` array of `NgModule`,
+         * but it requires us to know the component while writing the application code.
+         *
+         * Imagine a situation where we have to wait for an API call to decide about the component to
+         * bootstrap. We can use the `ngDoBootstrap` hook of the `NgModule` and call this method to
+         * dynamically bootstrap a component.
+         *
+         * {@example core/ts/platform/platform.ts region='componentSelector'}
+         *
+         * Optionally, a component can be mounted onto a DOM element that does not match the
+         * selector of the bootstrapped component.
+         *
+         * In the following example, we are providing a CSS selector to match the target element.
+         *
+         * {@example core/ts/platform/platform.ts region='cssSelector'}
+         *
+         * While in this example, we are providing reference to a DOM node.
+         *
+         * {@example core/ts/platform/platform.ts region='domNode'}
