What changes between Create React App and Vite?

  • react-scripts replaced by vite and @vitejs/plugin-react; package.json scripts rewritten
  • Environment variables prefix changes from REACT_APP_ to VITE_ across all files
  • index.html moves from public/ to project root and adds <script type="module" src> entry point
  • Proxy configuration moves from package.json proxy field to vite.config.ts server.proxy
  • Jest replaced by Vitest for testing (optional but recommended); test config migration
  • SVG imports change: react-scripts inline SVGs via SVGR by default; Vite needs explicit plugin
  • Absolute imports using jsconfig/tsconfig paths need alias configuration in vite.config.ts
  • CSS Modules, SASS, and PostCSS configurations carry over but may need plugin adjustments

Frequently Asked Questions

Why should I migrate from Create React App to Vite?

CRA is no longer maintained and its Webpack-based build is significantly slower than Vite's ESM-powered dev server. Vite offers sub-second hot module replacement, faster builds, and an active ecosystem. The React team now recommends frameworks or Vite over CRA.

Is migrating from CRA to Vite safe for production apps?

Yes. Nivo handles the full migration: config files, environment variables, import paths, proxy setup, and build scripts. Your React components and business logic remain untouched.

How long does a CRA to Vite migration take?

Most projects complete in under 10 minutes. The migration involves config generation, environment variable renaming, and index.html restructuring. Nivo handles all of these automatically.

Do I need to rewrite my tests?

Your test files remain the same, but the test runner changes. Nivo optionally migrates from Jest to Vitest, which has a Jest-compatible API. Most tests work with minimal or zero changes to assertions and mocks.

What about CRACO or react-app-rewired customizations?

Nivo detects CRACO and react-app-rewired configs, extracts your customizations (Webpack aliases, Babel plugins, PostCSS config), and translates them into the equivalent vite.config.ts settings.

Will my CI/CD pipeline need changes?

Yes, the build command changes from 'react-scripts build' to 'vite build' and the output directory changes from build/ to dist/. Nivo updates your package.json scripts; you may need to update CI config paths manually.
