Question 1

How do I add middleware like logging or auth to HttpRouter?

Accepted Answer

HttpRouter is minimalistic; you chain middleware by wrapping handlers or using adapter functions. The README provides an example for basic authentication by creating a custom wrapper function that intercepts requests.

Question 2

HttpRouter vs Gin: which is better for building APIs in Go?

Accepted Answer

HttpRouter offers raw routing speed and explicit matches, ideal for performance-critical APIs. Gin is a full framework built on HttpRouter with built-in middleware and features, but adds overhead. Choose HttpRouter for control and speed, Gin for convenience.

Question 3

How to serve static files with HttpRouter without breaking routes?

Accepted Answer

Use the ServeFiles method for specific catch-all routes like /static/*filepath, or set the NotFound handler to a http.FileServer for fallback serving, as shown in the README with examples for clean separation from dynamic routes.

Question 4

Can HttpRouter handle CORS preflight requests properly?

Accepted Answer

Yes, by customizing the GlobalOPTIONS handler to set CORS headers and adjust status codes for OPTIONS requests, as detailed in the documentation to support cross-origin resource sharing.

Question 5

How to recover from panics in HttpRouter handlers?

Accepted Answer

Set a PanicHandler function on the router to log errors and return HTTP error responses, preventing server crashes. The README explains this with configurable options for graceful error handling.

Question 6

Is HttpRouter good for large-scale microservices with many routes?

Accepted Answer

Yes, its radix tree scales efficiently with long paths and numerous routes, and low memory usage suits microservices. However, you'll need to implement cross-cutting concerns like monitoring or rate limiting externally.
