egg

Egg is an open-source Node.js framework designed for building enterprise applications and frameworks, built on top of Koa. According to its README, it emphasizes four core features: built-in process management, a plugin system, framework customization, and a large ecosystem of community plugins. The project is organized as a monorepo. The main framework lives in `packages/egg`, alongside CommonJS and TypeScript example applications and a documentation site. Dependency management uses a catalog mode for consistent versions across packages, and the README documents development commands for installing, building, and testing all packages or individual ones. For local development, the README notes that some data-access, ORM, Redis, and benchmark test paths require local MySQL and Redis services. It provides commands to start, check, stop, and reset repository-aligned Docker services, defaulting to MySQL 8 and Redis 7 on standard host ports, with environment variables available to override ports and images. It also lists specific fixtures and test files that assume those default ports. The quickstart requires Node.js 22.18.0 or newer and walks through creating, installing, and running a project, then opening it in a browser. Documentation, plugin and framework listings, and examples are linked from the README, which also covers contribution guidelines, sponsors, and an MIT license.
