routing

The router component provides us a way to define routes that are mapped to handlers that process the request. Crema uses [[ https://github.com/gorilla/mux | Gorilla Mux ]]-based HTTP router and it works almost the same way. Crema uses method **server.AddRoutes()** to register new endpoints. The method requires three parameters: - HTTP Method - URL - Handler Function Let's start writing a sample endpoint: ``` server.AddRoutes(http.MethodGet, "/hello", helloHandler) ``` From the example above, we register a route mapping an URL path “**///hello//**” to a handler “**//helloHandler//**” which is requested using **//HTTP GET//**. Like Gorilla Mux, paths can have variables too. The variables are defined using the format **//{var}//**. For example: ``` server.AddRoutes(http.MethodGet, “/users/{id}”, userHandler) server.AddRoutes(http.MethodGet, “/users/{name}”, userHandler) ``` That's it!
