xterm-the-terminal-emulator and its three addons (fit, search, serialize) used to be imported at module scope by Terminal.tsx, BashExecModal.tsx, and HostConsole.tsx along with xterm's CSS. Even though only Terminal.tsx is rendered eagerly inside the editor layout, the static imports forced the ~660 KB xterm chunk plus the xterm.css bytes into every cold app start regardless of whether a user ever opened a terminal. Move the bootstrap into a new frontend/src/lib/xtermLoader.ts module. loadXtermModules() Promise.alls the four addon imports plus the CSS, caches the result on a shared promise, and returns the constructors. On rejection the cache is cleared so the next mount can retry instead of rethrowing the same failed promise. Three consumers (Terminal, BashExecModal, HostConsole) swap their value imports for type-only InstanceType aliases from the loader, then call loadXtermModules() inside their existing useEffect. A mounted/cancelled flag in each effect closure prevents initialisation if the component unmounts during the load. The vite.config.ts manualChunks group from #823 already groups all @xterm/* packages into the xterm chunk, so it now loads on demand instead of being bundled into the entry chunk.
React + TypeScript + Vite
This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
Currently, two official plugins are available:
- @vitejs/plugin-react uses Babel (or oxc when used in rolldown-vite) for Fast Refresh
- @vitejs/plugin-react-swc uses SWC for Fast Refresh
React Compiler
The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see this documentation.
Expanding the ESLint configuration
If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
export default defineConfig([
globalIgnores(['dist']),
{
files: ['**/*.{ts,tsx}'],
extends: [
// Other configs...
// Remove tseslint.configs.recommended and replace with this
tseslint.configs.recommendedTypeChecked,
// Alternatively, use this for stricter rules
tseslint.configs.strictTypeChecked,
// Optionally, add this for stylistic rules
tseslint.configs.stylisticTypeChecked,
// Other configs...
],
languageOptions: {
parserOptions: {
project: ['./tsconfig.node.json', './tsconfig.app.json'],
tsconfigRootDir: import.meta.dirname,
},
// other options...
},
},
])
You can also install eslint-plugin-react-x and eslint-plugin-react-dom for React-specific lint rules:
// eslint.config.js
import reactX from 'eslint-plugin-react-x'
import reactDom from 'eslint-plugin-react-dom'
export default defineConfig([
globalIgnores(['dist']),
{
files: ['**/*.{ts,tsx}'],
extends: [
// Other configs...
// Enable lint rules for React
reactX.configs['recommended-typescript'],
// Enable lint rules for React DOM
reactDom.configs.recommended,
],
languageOptions: {
parserOptions: {
project: ['./tsconfig.node.json', './tsconfig.app.json'],
tsconfigRootDir: import.meta.dirname,
},
// other options...
},
},
])
