What it is

chi is a lightweight HTTP router library for Go (under 1000 LOC) that composes handlers using the standard net/http interface and Go's context package. It enables building modular, maintainable REST APIs by organizing routes into middleware chains, route groups, and sub-routers without external dependencies. Single-package monolith with chi.go as the main router, middleware/ subdirectory containing optional handlers (e.g., basic_auth.go), context.go for request-scoped values, and chain.go for handler composition. The _examples/ directory contains 11+ runnable reference implementations (hello-world, rest, todos-resource, versions, etc.) demonstrating patterns.

Start here

Open these first:

• chi.go — Core router interface and public API entry point; defines the Router type and essential routing methods.
• mux.go — Implements the multiplexer that handles request routing, pattern matching, and handler dispatch.
• tree.go — Implements the radix tree data structure for efficient route matching and pattern traversal.
• context.go — Manages request-scoped context values and signals passed through the middleware chain.
• chain.go — Implements middleware chaining and composition logic for handler wrapping.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

git clone https://github.com/go-chi/chi.git
cd chi
go mod download
cd _examples/hello-world
go run main.go

Daily commands:

From Makefile (invocation not specified in data), or run examples directly: go run _examples/hello-world/main.go starts an HTTP server on :3000. Each _examples/ subdirectory is standalone with its own go.mod.

Key cautions & unknowns

• No evidence of test suite provided in the file list (no *_test.go files shown except context_test.go), so test coverage details are unknown. Middleware subpackages (render, docgen) are separate repos…
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
