Single-bundle build was tripping vite's 500 kB warning per chunk and forcing every user to re-download the entire app on every deploy. Manual chunks split the bundle along natural library boundaries so: - Rarely-changing vendor libs (react-dom, react-router, lucide-react, asciinema-player) cache across deploys. - App code lives in its own `index-*.js` that's the only chunk that changes when we ship feature work. Split shape (manualChunks fn in vite.config.ts): - charts — recharts + d3-* - player — asciinema-player - icons — lucide-react - router — react-router / react-router-dom - react-dom, react - vendor — everything else in node_modules Resulting bundle sizes (gzip): index (app): 246 kB (gz 63) react-dom: 182 kB (gz 57) player: 176 kB (gz 65) router: 42 kB (gz 15) vendor: 36 kB (gz 14) icons: 29 kB (gz 10) Every chunk under the 600 kB ceiling we now set explicitly. The old ~705 kB single-chunk deploy is gone. No code changes — config only.
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 Oxc
- @vitejs/plugin-react-swc uses SWC
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...
},
},
])
