Httprouter
httprouter is a high-performance HTTP request router for Go that maps incoming network requests to specific handler functions using a radix tree. It functions as a request dispatcher and path parameter parser, organizing URL paths in a tree structure to ensure efficient lookups.
The router specializes in capturing dynamic segments and catch-all wildcards from URL paths to pass directly into request handlers. It implements method-specific routing and automatically manages responses for unsupported HTTP methods.
The library covers broader capabilities including request normalization through trailing-slash redirects, static asset serving by mapping paths to the file system, and middleware integration for recovering from request panics.
Features
- HTTP Routers - Implements a high-performance system for mapping network requests to handler functions based on URL patterns.
- Radix Tree Routers - Uses a high-performance radix tree structure to map URL paths to handlers with constant-time lookup.
- Path Variable Extractors - Maps requests to handlers using named parameters and catch-all wildcards within the URL path.
- Resource Path Matching - Supports catch-all wildcard patterns to capture all remaining segments of a URL path.
- HTTP Request Handlers - Efficiently routes URL paths to specific handler functions using a radix tree.
- High-Performance HTTP Servers - Provides high-performance HTTP routing using a fast radix tree for low latency and high throughput.
- Request Parameter Parsers - Extracts dynamic path segments and catch-all wildcards from URLs to pass as parameters to handlers.
- RESTful API Frameworks - Maps dynamic URL segments and named parameters to controllers for building scalable REST API endpoints.
- HTTP Routing - Maps incoming requests to specific handlers based on path matching and HTTP methods using a search tree.
- Dynamic Segment Extraction - Captures dynamic path segments using named wildcards to pass specific values directly into request handlers.
- Zero-Allocation Path Parsing - Parses path variables directly from the request URI slice to minimize memory allocations during routing.
- Method-Specific Trees - Implements separate routing trees for each HTTP method to avoid unnecessary checks during path traversal.
- Path Normalization - Redirects requests to correct URLs by removing trailing slashes and redundant path elements.
- Request Middleware - Includes middleware for intercepting requests to handle panics and manage custom error responses.
- URL Normalization Utilities - Redirects clients to correct paths by fixing trailing slashes and performing case-insensitive lookups.
- URL Redirections - Automatically normalizes request paths by issuing redirects when trailing slash mismatches occur.
- HTTP Routing - High-performance HTTP router.
- राउटिंग और मिडलवेयर - High-performance request router that scales efficiently.
- Web Frameworks - High-performance HTTP request router.
