chi is a lightweight, idiomatic and composable router for building Go HTTP services. It's
especially good at helping you write large REST API services that are kept maintainable as your
project grows and changes. chi is built on the new context package introduced in Go 1.7 to
handle signaling, cancelation and request-scoped values across a handler chain.
The focus of the project has been to seek out an elegant and comfortable design for writing REST API servers, written during the development of the Pressly API service that powers our public API service, which in turn powers all of our client-side applications.
The key considerations of chi's design are: project structure, maintainability, standard http
handlers (stdlib-only), developer productivity, and deconstructing a large system into many small
parts. The core router github.com/go-chi/chi is quite small (less than 1000 LOC), but we've also
included some useful/optional subpackages: middleware, render
and docgen. We hope you enjoy it too!
- Lightweight - cloc'd in ~1000 LOC for the chi router
- Fast - yes, see benchmarks
- 100% compatible with net/http - use any http or middleware pkg in the ecosystem that is also compatible with
net/http - Designed for modular/composable APIs - middlewares, inline middlewares, route groups and sub-router mounting
- Context control - built on new
contextpackage, providing value chaining, cancellations and timeouts - Robust - in production at Pressly, CloudFlare, Heroku, 99Designs, and many others (see discussion)
- Doc generation -
docgenauto-generates routing documentation from your source to JSON or Markdown - Go.mod support - as of v5, go.mod support (see CHANGELOG)
- No external dependencies - plain ol' Go stdlib + net/http
See examples for a variety of examples.
