What is evjs?

ev = Evaluation · Evolution — evaluate across runtimes, evolve with AI tooling.

evjs is a zero-config React fullstack framework built on TanStack Router, TanStack Query, and Hono. It provides a seamless development experience for building type-safe, full-stack web applications.

Features

• Convention over Configuration — ev dev / ev build, no boilerplate needed
• Type-Safe Routing — TanStack Router with full inference
• Data Fetching — TanStack Query with built-in proxies
• Server Functions — "use server" directive, auto-discovered at build time
• Pluggable Transport — HTTP, WebSocket, or custom via ServerTransport
• Plugin System — extend builds with custom module rules (Tailwind, SVG, etc.)
• Route Handlers — Standard Request/Response REST endpoints via route()
• Typed Errors — ServerError flows structured data from server → client
• Multi-Runtime — Hono-based server with Node, Deno, Bun, Edge adapters
