# Project coding standards
## Generic Communication Guidelines
- Be succint and be aware that expansive generative AI answers are costly and slow
- Avoid providing explanations, trying to teach unless asked for, your chat partner is an expert
- Stop apologising if corrected, just provide the correct information or code
- Prefer code unless asked for explanation
- Stop summarizing what you've changed after modifications unless asked for
## TypeScript Guidelines
- Use TypeScript for all new code
- Where possible, prefer implementations without allocation
- When there is an option, opt for more performant solutions and trade RAM usage for less CPU cycles
- Prefer immutable data (const, readonly)
- Use optional chaining (?.) and nullish coalescing (??) operators
## React Guidelines
- Use functional components with hooks
- Follow the React hooks rules (no conditional hooks)
- Keep components small and focused
- Use CSS modules for component styling
## Naming Conventions
- Use PascalCase for component names, interfaces, and type aliases
- Use camelCase for variables, functions, and methods
- Use ALL_CAPS for constants
## Error Handling
- Use try/catch blocks for async operations
- Implement proper error boundaries in React components
- Always log errors with contextual information
## Testing
- Always attempt to fix #problems
- Always offer to run `yarn test:app` in the project root after modifications are complete and attempt fixing the issues reported
## Types
- Always include `packages/math/src/types.ts` in the context when your write math related code and always use the Point type instead of { x, y}

# CLAUDE.md
## Project Structure
Excalidraw is a **monorepo** with a clear separation between the core library and the application:
- **`packages/excalidraw/`** - Main React component library published to npm as `@excalidraw/excalidraw`
- **`excalidraw-app/`** - Full-featured web application (excalidraw.com) that uses the library
- **`packages/`** - Core packages: `@excalidraw/common`, `@excalidraw/element`, `@excalidraw/math`, `@excalidraw/utils`
- **`examples/`** - Integration examples (NextJS, browser script)
## Development Workflow
1. **Package Development**: Work in `packages/*` for editor features
2. **App Development**: Work in `excalidraw-app/` for app-specific features
3. **Testing**: Always run `yarn test:update` before committing
4. **Type Safety**: Use `yarn test:typecheck` to verify TypeScript
## Development Commands
```bash
yarn test:typecheck # TypeScript type checking
yarn test:update # Run all tests (with snapshot updates)
yarn fix # Auto-fix formatting and linting issues
```
## Architecture Notes
### Package System
- Uses Yarn workspaces for monorepo management
- Internal packages use path aliases (see `vitest.config.mts`)
- Build system uses esbuild for packages, Vite for the app
- TypeScript throughout with strict configuration

## Releasing
### Create a test release
You can create a test release by posting the below comment in your pull request:
```bash
@excalibot trigger release
```
Once the version is released `@excalibot` will post a comment with the release version.
### Creating a production release
To release the next stable version follow the below steps:
```bash
yarn release --tag=latest --version=0.19.0
yarn prerelease:excalidraw
```
You will need to pass the `latest` tag with `version` for which you want to create the release. This will make the changes needed before publishing the packages into NPM, like updating dependencies of all `@excalidraw/*` packages, generating new entries in `CHANGELOG.md` and more.
You need to pass the `version` for which you want to create the release. This will make the changes needed before making the release like updating `package.json`, `changelog` and more.
The next step is to run the `release` script:
```bash
yarn release:excalidraw
```
This will publish the package.
Right now there are two steps to create a production release but once this works fine these scripts will be combined and more automation will be done.

### Self-hosting fonts
### Static assets
By default, Excalidraw will try to download all the used fonts from the [CDN](https://esm.run/@excalidraw/excalidraw/dist/prod).
Excalidraw depends on assets such as localization files (if you opt to use them), fonts, and others.
For self-hosting purposes, you'll have to copy the content of the folder `node_modules/@excalidraw/excalidraw/dist/prod/fonts` to the path where your assets should be served from (i.e. `public/` directory in your project). In that case, you should also set `window.EXCALIDRAW_ASSET_PATH` to the very same path, i.e. `/` in case it's in the root:
By default these assets are loaded from a public CDN [`https://unpkg.com/@excalidraw/excalidraw/dist/prod/`](https://unpkg.com/@excalidraw/excalidraw/dist/prod/), so you don't need to do anything on your end.
However, if you want to host these files yourself, you can find them in your `node_modules/@excalidraw/excalidraw/dist` directory, in folders `excalidraw-assets` (for production) and `excalidraw-assets-dev` (for development).
Copy these folders to your static assets directory, and add a `window.EXCALIDRAW_ASSET_PATH` variable in your `index.html` or `index.js` entry file pointing to your public assets path (relative). For example, if you serve your assets from the root of your hostname, you would do:
