Egg Core Framework

egg-core, at version 5.5.1, is the foundational module of the Egg.js framework, a highly extensible web framework for Node.js built upon Koa. It provides the core loading mechanisms, plugin system, and application context management essential for enterprise-grade web applications. While the unscoped `egg-core` package saw its last update to 5.5.1 in January 2025, active development has since transitioned to its successor, `@eggjs/core`. The `@eggjs/core` package, with `v6.5.0` as its current stable release, continues to evolve the framework with features like enhanced TypeScript support, Vitest integration, and refined lifecycle management. Both `egg-core` and `@eggjs/core` adhere to a convention-over-configuration philosophy, offering a powerful plugin system and environment-aware configurations for extensible and maintainable server-side applications. This package is typically consumed as a dependency by the main `egg` framework, rather than being directly integrated into end-user applications.
