Routing

NanoPhoto uses TanStack Router with a file-based routing system. Routes are managed as files in the src/routes directory.

Adding A Route

To add a new route to NanoPhoto, create a new file in the ./src/routes directory.

TanStack will automatically generate the content of the route file for you.

Now that you have two routes you can use a Link component to navigate between them.

Adding Links

To use SPA (Single Page Application) navigation you will need to import the Link component from @tanstack/react-router.

import { Link } from "@tanstack/react-router";

Then anywhere in your JSX you can use it like so:

<Link to="/about">About</Link>

This will create a link that will navigate to the /about route.

More information on the Link component can be found in the Link documentation.

Using A Layout

In the File Based Routing setup the layout is located in src/routes/__root.tsx. Anything you add to the root route will appear in all the routes. The route content will appear in the JSX where you use the <Outlet /> component.

Here is an example layout that includes a header:

import { Outlet, createRootRoute } from "@tanstack/react-router";
import { TanStackRouterDevtools } from "@tanstack/react-router-devtools";

import { Link } from "@tanstack/react-router";

export const Route = createRootRoute({
  component: () => (
    <>
      <header>
        <nav>
          <Link to="/">Home</Link>
          <Link to="/about">About</Link>
        </nav>
      </header>
      <Outlet />
      <TanStackRouterDevtools />
    </>
  ),
});

The <TanStackRouterDevtools /> component is not required so you can remove it if you don't want it in your layout.

More information on layouts can be found in the Layouts documentation.

Data Fetching

There are multiple ways to fetch data in your application. You can use TanStack Query to fetch data from a server. But you can also use the loader functionality built into TanStack Router to load the data for a route before it's rendered.

For example:

const peopleRoute = createRoute({
  getParentRoute: () => rootRoute,
  path: "/people",
  loader: async () => {
    const response = await fetch("https://swapi.dev/api/people");
    return response.json() as Promise<{
      results: {
        name: string;
      }[];
    }>;
  },
  component: () => {
    const data = peopleRoute.useLoaderData();
    return (
      <ul>
        {data.results.map((person) => (
          <li key={person.name}>{person.name}</li>
        ))}
      </ul>
    );
  },
});

Loaders simplify your data fetching logic dramatically. Check out more information in the Loader documentation.

React-Query

React-Query is an excellent addition or alternative to route loading and integrating it into you application is a breeze.

First add your dependencies:

pnpm add @tanstack/react-query @tanstack/react-query-devtools

Next we'll need to create a query client and provider. We recommend putting those in main.tsx.

import { QueryClient, QueryClientProvider } from "@tanstack/react-query";

// ...

const queryClient = new QueryClient();

// ...

if (!rootElement.innerHTML) {
  const root = ReactDOM.createRoot(rootElement);

  root.render(
    <QueryClientProvider client={queryClient}>
      <RouterProvider router={router} />
    </QueryClientProvider>
  );
}

You can also add TanStack Query Devtools to the root route (optional).

import { ReactQueryDevtools } from "@tanstack/react-query-devtools";

const rootRoute = createRootRoute({
  component: () => (
    <>
      <Outlet />
      <ReactQueryDevtools buttonPosition="top-right" />
      <TanStackRouterDevtools />
    </>
  ),
});

Now you can use useQuery to fetch your data.

import { useQuery } from "@tanstack/react-query";

import "./App.css";

function App() {
  const { data } = useQuery({
    queryKey: ["people"],
    queryFn: () =>
      fetch("https://swapi.dev/api/people")
        .then((res) => res.json())
        .then((data) => data.results as { name: string }[]),
    initialData: [],
  });

  return (
    <div>
      <ul>
        {data.map((person) => (
          <li key={person.name}>{person.name}</li>
        ))}
      </ul>
    </div>
  );
}

export default App;

State Management

Another common requirement for React applications is state management. There are many options for state management in React. TanStack Store provides a great starting point for your project.

First you need to add TanStack Store as a dependency:

pnpm add @tanstack/store

Now let's create a simple counter in the src/App.tsx file as a demonstration.

import { useStore } from "@tanstack/react-store";
import { Store } from "@tanstack/store";
import "./App.css";

const countStore = new Store(0);

function App() {
  const count = useStore(countStore);
  return (
    <div>
      <button onClick={() => countStore.setState((n) => n + 1)}>
        Increment - {count}
      </button>
    </div>
  );
}

export default App;

One of the many nice features of TanStack Store is the ability to derive state from other state. That derived state will update when the base state updates.

Let's check this out by doubling the count using derived state.

import { useStore } from "@tanstack/react-store";
import { Store, Derived } from "@tanstack/store";
import "./App.css";

const countStore = new Store(0);

const doubledStore = new Derived({
  fn: () => countStore.state * 2,
  deps: [countStore],
});
doubledStore.mount();

function App() {
  const count = useStore(countStore);
  const doubledCount = useStore(doubledStore);

  return (
    <div>
      <button onClick={() => countStore.setState((n) => n + 1)}>
        Increment - {count}
      </button>
      <div>Doubled - {doubledCount}</div>
    </div>
  );
}

export default App;

We use the Derived class to create a new store that is derived from another store. The Derived class has a mount method that will start the derived store updating.

Once we've created the derived store we can use it in the App component just like we would any other store using the useStore hook.

You can find out everything you need to know on how to use TanStack Store in the TanStack Store documentation.
