Question 1

how does xmux compare to httprouter in terms of performance?

Accepted Answer

Xmux is a fork of httprouter with added context support, introducing a small overhead due to context allocation—benchmarks show it's slightly slower for parameterized routes but still faster than many alternatives like Chi. However, it maintains zero garbage allocation for static routes.

Question 2

how to implement authentication middleware with xmux?

Accepted Answer

You can chain middleware using xhandler.Chain or write custom handlers that implement xhandler.HandlerC. The README provides a detailed example of Basic Authentication middleware that wraps the next handler and checks credentials.

Question 3

does xmux support nested routes or sub-routers?

Accepted Answer

Xmux supports RouteGroups for grouping routes without overhead, but it lacks built-in nested routing or sub-router features; you must define paths explicitly or use separate mux instances, as shown in the multi-domain example.

Question 4

xmux or chi for building REST APIs?

Accepted Answer

Choose Xmux for raw speed and minimal memory footprint, as it outperforms Chi in benchmarks. Opt for Chi if you need more built-in features like middleware and easier setup, but accept higher overhead.

Question 5

how to handle custom 404 pages in xmux?

Accepted Answer

Set a custom NotFound handler on the muxer instance to define specific responses for missing routes, similar to the PanicHandler and MethodNotAllowed handlers documented in the README's features section.

Question 6

can i use xmux with standard net/http middleware?

Accepted Answer

Yes, but with limitations: adapters are provided for http.Handler, but parameters won't be accessible via context. For full functionality, use xhandler-compatible middleware or wrap handlers accordingly.
