DP-Koa Framework Core

dp-koa-framework-core is a v2 upgrade of the DP-Koa framework core at version 0.1.8, a lightweight, decorator-driven Node.js web framework built on Koa. It enables class-based controllers with decorators for routing (@Get, @Post, @Put, @Del, @All), parameter injection (@Body, @Query, @Params, @State, @Session, @Headers), DTO validation using class-validator, response control (@ResponseCode, @ResponseHeader), HTTP redirects, and an extensible annotation processor system for cross-cutting concerns like logging, authentication, and rate limiting. It supports both legacy and new annotation execution modes switchable via environment variable (USE_NEW_ANNOTATION_SYSTEM=1). Ships TypeScript types. Release cadence is irregular; actively maintained.
