GRRT (Go Request RouTer)

GRRT (Go Request RouTer) is a direct replacement for the archived gorilla/mux. It has built-in CORS and Method based routing.

Replaces gorilla/mux with one line of code

Features

• Request Routing
• Method Based Routing
• CORS

Package GolangToolKits/grrt implements a request router and dispatcher for handling incoming requests to their associated handler.

The name mux stands for "HTTP request multiplexer". Like the standard http.ServeMux, grrt.Router matches incoming requests against a list of registered routes and calls a handler for the route that matches the URL. The main features are:

• Replaces gorilla/mux with one line of code
• It implements the http.Handler interface so it is compatible with the standard http.ServeMux.
• URL hosts, paths and query values can be handled.
• Path variable can be used instead of query parameters with ease.
• Method base routing is easy
• CORS is built in with no need for additional modules.
