  • Express-style routing (app.get, app.put, app.post, etc.)
  • Named URL parameters
  • Named routes with URL generation
  • Responds to OPTIONS requests with allowed methods
  • Support for 405 Method Not Allowed and 501 Not Implemented

Migrating to 7 / Koa 2

  • The API has changed to match the new promise-based middleware signature of koa 2. See the koa 2.x readme for more information.
  • Middleware is now always run in the order declared by .use() (or .get(), etc.), which matches Express 4 API.

Call for Maintainers

This module is forked from the original koa-router due to its lack of activity. koa-router is the most widely used router module in the Koa community and we need maintainers. If you're interested in fixing bugs or implementing new features feel free to open a pull request. We'll be adding active contributors as collaborators.

Thanks to the original authors @alexmingoia and the original team for their great work.
