router

HTTP router based on radix trees.

Usage

Static

We can save any type of data inside the router. Here is an example storing strings for static routes:

router := router.New[string]()

router.Add("GET", "/hello", "Hello")
router.Add("GET", "/world", "World")

Parameters

The router supports parameters:

router.Add("GET", "/users/:id", "...")
router.Add("GET", "/users/:id/comments", "...")

Wildcards

The router can also fall back to a catch-all route which is useful for file servers:

router.Add("GET", "/images/*path", "...")

Benchmarks

Requesting every single route in github.txt (≈200 requests) in each iteration:

BenchmarkLookup-12                 33210             36134 ns/op           19488 B/op        337 allocs/op
BenchmarkLookupNoAlloc-12         103437             11331 ns/op               0 B/op          0 allocs/op

Embedding

If you'd like to embed this router into your own framework, please use LookupNoAlloc because it's much faster than Lookup.

To build an http server you would of course store request handlers (functions), not strings.
