Different Routers

Reitit ships with several different implementations for the Router protocol, originally based on the Pedestal implementation. router selects the most suitable implementation by inspecting the expanded routes. The implementation can be set manually using :router option, see configuring routers.

router	description
:linear-router	Matches the routes one-by-one starting from the top until a match is found. Works with any kind of routes.
:lookup-router	Fast router, uses hash-lookup to resolve the route. Valid if no paths have path or catch-all parameters.
:mixed-router	Creates internally a :linear-router and a :lookup-router and used them to effectively get best-of-both-worlds. Valid if there are no Route conflicts.
::single-static-path-router	Fastest possible router: valid only if there is one static route.
:prefix-tree-router	TODO: https://github.com/julienschmidt/httprouter#how-does-it-work

The router name can be asked from the router

(r/router-name router)
