Cloudflare has launched a new Vite plugin (v1.0), which streamlines the process of developing web applications on Cloudflare Workers by directly integrating the Workers runtime into the Vite build process and adding official support for React Router v7.
This plugin leverages Vite 6's environment API, enabling developers to run Worker code within the workerd runtime, ensuring consistency between development and production environments. Senior front-end engineer Michal Kuncio noted on X platform: By utilizing the @vite_js environment API, you can now simulate production environment behavior on the development server using Cloudflare Workers. Moreover, this integration capitalizes on the popularity of Vite as a fast build tool. Developer Shivani Sharma praised it on
for outperforming Create React App in terms of speed, bundling, and configuration flexibility, while also offering efficient hot module replacement and a robust plugin ecosystem. Vite 6 introduced the
environment API, a significant architectural change that allows the Vite development server to interact with various custom runtime environments, including workers. Cloudflare collaborated with the Vite team to develop this API.
The Cloudflare Vite plugin supports single-page applications (SPAs) built with frameworks like React, Vue, and Svelte. Developers can use the create-cloudflare CLI to create a new React SPA, which handles create-vite and configures the Cloudflare Vite plugin. Existing Vite SPA projects can be updated by adding the @cloudflare/vite-plugin dependency and wrangler.jsonc configuration file. The plugin integrates the Vite development server with Workers Assets for front-end applications. Additionally, the plugin simplifies the development and deployment workflow for applications with a Worker backend. The Vite development server runs the Worker in the Cloudflare Workers runtime. Developers can modify Worker code (e.g., in api/index.ts) and view changes without losing UI state. The plugin also streamlines the build and deployment process: vite build outputs client and server code, vite preview allows previewing the build within the Workers runtime, and wrangler deploys the application directly.
The Cloudflare Vite plugin also supports
React Router v7. Developers can use the create-cloudflare CLI to create new React Router applications. Software engineer Ardizanki, who focuses on the React ecosystem, tweeted: React Router is the best bridge from React 18 to 19. It can be used as a complete framework or as a library within your own architecture.
This plugin simplifies Worker configuration, giving developers more control.
Finally, the plugin supports the full Cloudflare developer platform, including
KV, D1, service bindings, RPC, durable objects, workflows, and Workers AI. Existing Workers can be adapted by installing the @cloudflare/vite-plugin dependency and adding Vite configuration.
