Chi
Chi is a lightweight, idiomatic router and middleware framework for building web services in Go. It is designed to integrate directly with the standard library, providing a set of utilities for managing HTTP request routing, context propagation, and modular service composition.
The project distinguishes itself through a radix-tree-based routing system that supports recursive nesting, allowing developers to mount independent sub-routers onto specific path prefixes. This hierarchical structure enables the creation of organized, modular applications where request handlers are grouped and managed through consistent middleware chains.
The framework provides a comprehensive toolkit for API development, including capabilities for request context management, URL parameter extraction, and role-based access control. It includes built-in utilities for common request processing tasks such as logging, compression, and authentication, which can be composed into sequences to ensure consistent behavior across an entire application.
