Configuring Routers

Routers can be configured via options. Options allow things like clojure.spec validation for meta-data and fast, compiled handlers. The following options are available for the reitit.core/router:

key	description
:path	Base-path for routes
:routes	Initial resolved routes (default [])
:meta	Initial expanded route-meta vector (default [])
:expand	Function of arg opts => meta to expand route arg to route meta-data (default reitit.core/expand)
:coerce	Function of route opts => route to coerce resolved route, can throw or return nil
:compile	Function of route opts => result to compile a route handler
:conflicts	Function of {route #{route}} => side-effect to handle conflicting routes (default reitit.core/throw-on-conflicts!)
:router	Function of routes opts => router to override the actual router implementation
