Question 1

How do I add middleware to fasthttprouter?

Accepted Answer

Middleware can be chained before the router by using fasthttp.RequestHandler functions. The README provides examples like auth and multi-hosts middleware, and links to writing custom middleware, making it flexible but manual.

Question 2

Is fasthttprouter faster than httprouter?

Accepted Answer

Yes, according to benchmarks in the README, fasthttprouter is shown to be even faster than httprouter when used with fasthttp, due to optimizations specific to the fasthttp framework for high performance.

Question 3

Can I use fasthttprouter with net/http?

Accepted Answer

No, fasthttprouter is specifically designed for fasthttp and does not work with net/http. The README explains that fasthttp uses a different handler interface (RequestHandler), so it's incompatible with standard library tools.

Question 4

How to handle static files with fasthttprouter?

Accepted Answer

Static files can be served using the NotFound handler or by setting up a route with a catch-all parameter. The README suggests using paths like /static/*filepath for cleaner routing and to avoid sidestepping core rules.

Question 5

Does fasthttprouter support nested routes or groups?

Accepted Answer

The router supports hierarchical RESTful APIs through its tree structure, but for route grouping, you need to manage patterns manually as it doesn't have built-in group syntax like some frameworks (e.g., Gin).

Question 6

fasthttprouter or gin: which is better for high performance?

Accepted Answer

Fasthttprouter is optimized for fasthttp and likely faster in that context, while Gin is built on net/http. Choose fasthttprouter if you're committed to fasthttp for extreme speed; otherwise, Gin offers more features and net/http compatibility.

Question 7

What are the performance benchmarks for fasthttprouter?

Accepted Answer

The README includes benchmark graphs showing it handles 5000 concurrent clients with low latency, and it's cited as processing 17 million requests per day in production, validating its stability and speed.
