Bun supports .jsx and .tsx files out of the box. React just works with Bun.
Create a new React app with bun init --react. This gives you a template with a simple React app and a simple API server together in one full-stack app.
# Create a new React appbun init --react
# Run the app in development modebun dev
# Build as a static site for productionbun run build
# Run the server in productionbun startHot Reloading
Run bun dev to start the app in development mode. This will start the API server and the React app with hot reloading.
Full-Stack App
Run bun start to start the API server and frontend together in one process.
Static Site
Run bun run build to build the app as a static site. This will create a dist directory with the built app and all the assets.
