github.com/fasthttp/router (go): Package router is a trie based high performance HTTP request router.  A trivial example is:  The router matches incoming requests by the request method and the path. If a handler is registered for this path and method, the router delegates the request to that function. For the methods GET, POST, PUT, PATCH, DELETE and OPTIONS shortcut functions exist to register handles, for all other methods router.Handle can be used.  The registered path, against which the router matches incoming requests, can contain two types of parameters:  Named parameters are dynamic path segments. They match anything until the next '/' or the path end:  Catch-all parameters match anything until the path end, including the directory index (the '/' before the catch-all). Since they match anything until the end, catch-all parameters must always be the final path element.  The value of parameters is saved in ctx.UserValue(<key>), consisting each of a key and a value. The slice is passed to the Handle func as a third parameter. To retrieve the value of a parameter,gets by the name of the parameter
