What is Gin?
Gin is basically a micro-framework written in Go or Golang, used in building microservices or web applications. “Go” or as it is typically called “golang”, is a programming language designed by google. It is very similar to C but is known for its super fast compiling time, extensive standard library and high reliability and efficiency. Gin framework is mostly used for its minimalist approach, as it is very simple to build a request handling pipeline from modular, reusable pieces by writing middleware that essentially be plugged into one or more request handlers or groups of request handlers.
Why Use Gin Though?
The first and probably the most important reason to use Gin is its speed. This framework was built with a Radix tree based routing with a small memory footprint. It is built with a very simplistic approach and has only the basic features and libraries needed and is perfect for building REST APIs. It has an built in library (net/http), although not very flexible, lets you create a http server very easily. Gin also gives you easy to use routing interface, middleware support and built-in rendering in various formats like HTML, text, JSON, XML. The main advantage of Gin is that it makes writing code simpler yet you can write feature packed and high performance apps effortlessly.
Similar Frameworks From Golang
Golang or Go has other similar frameworks like Gin like Revel, Beego, Goji, Buffalo, Martini, Mango, Tiger Tonic and so on. These are all open source and feature packed frameworks. For instance, Buffalo and Revel has a Code Reload tool that lets you rebuild your projects easily with any change in files, Martini has a wide range of handlers and middleware, Goji has a Einhorn support and Beego has its own logging library and web frameworks. The Gin framework is much similar to the Martini framework while being 40 times faster.
