Go originated as a systems programming language. It takes the best of compiled statically typed languages like C and combine it with garbage collection. Go has some elegant features baked in for concurrency such as goroutines and channels.

As a high performance systems language supporting concurrency, Go is popular with high volume HTTP proxies and gateways along with lower level code like Docker and Kubernetes. While not popular with application programming and APIs yet, it’s usage is growing, especially as new frameworks mature. As a systems language, Go is not suited for data manipulation problems in data oriented applications due to limited constructs.

Background on Go

You can develop RESTful APIs without using frameworks, usually use one of the frameworks can make it a lot easier.

Go-Lang have several frameworks of varying popularity.

  • Beego - an open source framework to build and develop your applications in the Go way.
  • Buffalo - rapid web development with Go.
  • Echo - a minimalistic Go Web Framework.
  • Gin - featuring a Martini-like API.
  • Iris - claim to be the fastest web framework for Go, supporting MVC.
  • Revel - a full-stack web framework for Go-Lang.

Tutorials for Creating RESTFul APIs

Like most web pages, you usually build APIs on tops of an existing framework. The most popular frameworks in PHP are Laravel and CodeIgniter.

Tutorials for Creating GraphQL APIs

GraphQL is promoted as an alternative to RESTful API, you can read more about the background on GraphQL, and other types of APIs here.

Tutorials for Deployment

Azure seems to ended official support for Go according to announcement here.
