Fusion.js is Uber's open-source universal web framework for building React applications with server-side rendering out of the box. It uses a plugin-driven architecture that encapsulates frontend and backend logic, with built-in support for code splitting, hot module reloading, and testing utilities.

Use cases

• build server-side rendered react apps
• universal javascript framework with shared client and server code
• react framework with plugin architecture
• code splitting and bundle splitting for react
• full-stack react app with rpc data fetching
• react app with redux and ssr setup
• integrated testing setup for react apps

When to choose

• you want SSR React apps with minimal configuration
• you prefer a plugin-based architecture to encapsulate cross-cutting concerns
• you need universal code sharing between server and browser
• you want built-in testing, code splitting, and hot reloading out of the box

When to avoid

• you prefer mainstream ecosystems like Next.js or Remix with larger communities
• you need a framework with frequent updates and active development
• your project is a simple static site without server rendering needs
• you rely on a broad ecosystem of third-party integrations
