React is a frontend library for building user interfaces out of components. This workspace pairs it with Vite, so you get a dev server with instant hot reload and a built-in browser preview the moment the workspace boots.
Run npm run dev and Vite serves your app on port 3000. Edits show up instantly through hot module replacement, so the page updates as you save.
The full cloud editor with an integrated terminal, extensions and a .vscode folder that's already wired up for the workspace.
Clone, commit and push from the terminal, or connect a GitHub repo whenever you're ready.
Boots in about a minute, with dependencies already installed so you can start editing right away.
React is an open-source JavaScript library for building user interfaces. You describe your UI as small, reusable components, and React keeps the screen in sync with your data as it changes. It's one of the most widely used ways to build web apps today, and the skills carry over to React Native for mobile.
This workspace uses Vite as the build tool. Vite starts a dev server almost instantly and reloads only the parts of the page that changed, so the feedback loop while you code stays quick even as the app grows.
It's a Vite project set up for React with JSX. The entry point is src/main.jsx, which mounts the App component from src/App.jsx, and there's a small starter page you can edit straight away. An ESLint config and an index.html shell come included.
Anything you need beyond the basics, like a router, a state library or a UI kit, installs from the terminal as a normal npm package. There's no separate environment to configure.
Run npm run dev to start the Vite dev server on port 3000, and Studio opens your app in a built-in browser preview. As you edit files in src, the preview hot-reloads without a full refresh. When you're ready to ship, npm run build produces an optimized static bundle you can host anywhere.
Single-page apps, dashboards, marketing sites, internal tools or the front end of a larger product. Anything where you want a component-based UI with a fast dev loop and a build step that outputs plain static files.
It uses Vite. The dev server starts almost instantly and hot reload is fast. If you'd rather use Create React App, you can swap the dependencies and update the scripts, but most new React projects start with Vite now.
No, it ships as plain JavaScript with JSX files. If you prefer TypeScript, install it along with the React type packages and rename your files to .tsx.
Port 3000. Running npm run dev starts Vite there, and Studio opens it in the built-in browser preview automatically.
Install what you need from the terminal. For example, React Router for navigation, or a store like Redux or Zustand. They're all just npm packages, and Vite picks them up without extra config.
Run npm run build. Vite bundles your app into a static dist folder that you can deploy to any static host or CDN.
Yes. The React workspace runs on the free tier with no credit card required, so you can launch it and start building right away.
