Choo is a tiny 4kb JavaScript frontend framework for building sturdy single-page applications using vanilla JS and HTML. It combines an event-based state system (stores), a router, and DOM rendering with optional server-side rendering in Node.

Use cases

• build a tiny single-page app with minimal bundle size
• frontend framework with unidirectional data flow
• server-side render a JavaScript app in Node
• simple routing and state management without heavy tooling
• learn a minimal alternative to React or Vue
• build UI with vanilla JS and tagged template HTML

When to choose

• you need a very small bundle (~4kb) and simple API
• you prefer vanilla JS/HTML over framework-specific DSLs
• you want event-based stores and built-in routing
• you need lightweight server-side rendering

When to avoid

• you need a large ecosystem, tooling, and community support
• you rely on JSX, hooks, or React-compatible libraries
• you need long-term active development guarantees
• you want TypeScript-first ergonomics
