Building RESTful Web services with Go

Introducing httprouter, a lightweight HTTP router

httprouter, as the name suggests, routes the HTTP requests to particular handlers. Compared to the basic router, it has the following features:

• Allows variables in the route paths
• It matches the REST methods (GET, POST, PUT, and so on)
• No compromising on performance

We are going to discuss these qualities in more detail in the following section. Before that, there are a few noteworthy points that make httprouter an even better URL router:

• httprouter plays well with the inbuilt http.Handler
• httprouter explicitly says that a request can only match to one route or none
• The router's design encourages building sensible, hierarchical RESTful APIs
•  You can build efficient static file servers
