Svelte Lexical Redesign

This repo contains a prototype of a redesigned Svelte Lexical package. The goals for this redesign are:

1. Support modern editor features, particular hover toolbars and block editing UX
2. Allow users to use their own component libraries when building editors
3. Maintain Svelte Lexical & Lexical's modular and flexible design

The direction the codebase takes may make it prudent to break it up into several packages, but currently it includes only one prototype package.

Organization

The monorepo uses bun, especially due to its support of workspaces. Fresh packages were set up using bunx sv create, with the library option. Typescript, ESLint and Prettier. It is structured as follows:

*
├── apps/
│   └── docs/     - a static(ish) docs site using Starlight
├── pkgs/
│   ├── core/     - core reactive Svelte API to `lexical`
│   ├── float/    - hover toolbar API using `floating-ui`
│   └── modules/  - extension plugins & themes to `@lexical/{module}`
├── bun.lockb
├── package.json
└── README.md

Developing

1. Ensure you have bun installed
2. Go to project root and install: cd ./slexy and bun install
3. Run bun dev in the project root

This will run the website Astro dev server while executing svelte-package -w for each of the packages, ensure HMR for everything.

Docs

A skeleton docs site is added via Starlight, an Astro based static site builder designed specifically for docs.

This docs site is currently basically empty: the goal was to validate that its easy to develop the package with the docs, and to provide a place to test the package. Once the API has stabilized, I will start to document it here.

Example

A usage example is found in app/docs/src/lib/modern. It demostrates what I would consider idiomatic editor code structure for the new API. To view it in action, go to the docs folder and run bun dev, and browse to localhost:4321. Then open the 'Getting Started' page (big button in the frontpage splash).
