How to use httptreemux with Go's context package?

Use the UsingContext method on a router or group, or create a new router with NewContextMux, then access parameters via httptreemux.ContextParams in your handlers. This allows seamless integration with context-aware middleware.

httptreemux vs httprouter: which is better?

httptreemux offers more flexible routing with overlapping patterns but is slightly slower and not maintained. httprouter is faster and more popular but has stricter rules, so choose based on flexibility vs. performance and maintenance needs.

How to handle middleware in httptreemux?

httptreemux provides Use and UseHandler functions for custom middleware chains, but it has no built-in middleware, so you need to write or integrate third-party middleware manually, as noted in the README's middleware section.

Does httptreemux support case-insensitive routing?

Yes, set the CaseInsensitive property to true before defining routes to allow case-insensitive matching, but it must be set early to avoid side effects, as mentioned in the routing rules.

What's the deal with catch-all parameters in httptreemux?

Unlike httprouter, httptreemux does not match empty catch-alls (e.g., /images/ won't match with /images/*path); you need a separate route without the catch-all for such cases, as explained in the routing priority section.

How does trailing slash redirection work?

By default, it automatically redirects between slash and non-slash versions for cleaner URLs, but this can be disabled with RedirectTrailingSlash or adjusted for catch-alls with RemoveCatchAllTrailingSlash settings.

Is httptreemux safe for concurrent route additions?

Yes, it uses an RWMutex for safety; set SafeAddRoutesWhileRunning to true to avoid race conditions when adding routes after the server starts, as detailed in the concurrency section.

httptreemux — High-Speed Tree-Based Go Router

What is httptreemux?

httptreemux is a tree-based HTTP router for Go designed for high-speed routing with flexible pattern matching. It solves the need for efficient URL routing in web applications by allowing overlapping wildcard and static routes, making it easier to design complex routing logic without sacrificing performance.

Target Audience

Go developers building web servers or APIs that require fast and flexible URL routing, especially those who need overlapping route patterns or efficient tree-based matching.

Value Proposition

Developers choose httptreemux for its relaxed routing rules, which allow a path segment to be a wildcard in one route and static in another, combined with near-httprouter performance and built-in concurrency safety for route management.

High-speed, flexible tree-based HTTP router for Go.

Use Cases

Best For

Building high-performance REST APIs in Go
Implementing complex URL patterns with overlapping wildcards
Creating routing groups for API versioning or prefixes
Developing web servers that require efficient tree-based route matching
Handling trailing slash redirects and canonical URL management
Writing middleware-friendly routers with context support

Not Ideal For

Projects requiring the absolute fastest router performance, as benchmarks show it's slightly slower than httprouter
Teams needing built-in middleware or extensive framework integrations out-of-the-box
Applications where active maintenance and security updates are critical, since the project is explicitly not maintained
Use cases relying on specific behaviors from other routers, like automatic query string modification as in gorilla/pat

Pros & Cons

Pros

Flexible Route Patterns

Allows overlapping wildcards and static tokens in different routes, enabling complex URL designs without conflicts, as shown in the routing rules examples.

Efficient Tree-Based Matching

Uses a patricia tree for high-speed URL routing, inspired by httprouter, with performance close to it in benchmarks.

Routing Group Organization

Supports creating clusters of routes with shared prefixes via NewGroup, making API versioning or path management cleaner.

Context and Handler Support

Compatible with Go's context package and http.HandlerFunc through UsingContext or NewContextMux, facilitating modern middleware integration.

Concurrency Safety

Includes an RWMutex for safe route addition from multiple goroutines when SafeAddRoutesWhileRunning is enabled, as detailed in the concurrency section.

Cons

No Longer Maintained

The README warns that the project is not maintained, risking unpatched bugs and lack of updates for new Go versions or features.

Slightly Slower Performance

Benchmarks indicate it's close to but slower than httprouter, making it less ideal for edge cases where every nanosecond counts.

Limited Built-in Features

Light on features; lacks built-in middleware and has unexpected differences, such as no automatic query string modification like gorilla/pat.

Complex Escaped Slash Handling

Requires careful configuration with PathSource and EscapeAddedRoutes to properly handle URLs with escaped characters, adding setup complexity.
