The word Mux stands for the multiplexer. gorilla/mux is a multiplexer designed to multiplex HTTP routes (URLs) to different handlers. Handlers are the functions that can handle the given requests. gorilla/mux is a wonderful package for writing beautiful routes for our API servers.
gorilla/mux provides tons of options to control how routing is done to your web application. It allows a lot of features, such as:
Path-based matching
Query-based matching
Domain-based matching
Sub-domain-based matching
Reverse URL generation
Which type of routing to use depends on the types of clients requesting the server. We first see the installation and then a basic example to understand the gorilla/mux package.
