A quick guide to creating a RESTful API with the Golang (Go) programming language. This is a quick course for those interested in learning the Golang (Go) programming language and creating the REST API using the Golang language and other third-party packages.

You will create a RESTful API using Golang (Go), which will perform CRUD or CREATE, READ, UPDATE and DELETE operations for the data that you save in the PostgreSQL database.
You will work with structures and slices to create your model, store and transfer data. You will create a router to register your endpoints and api handler functions. You will also learn how to reorganize your code and create a modular file structure.

You will use technologies such as PostgreSQL database for permanent records, Postman for creating API requests and third-party packages such as gorilla / mux for routing, and other packages for loading environment variables, creating HTTP requests, encoding and decoding JSON, string conversions and validation types.
The programming language Go (Golang) has become very popular among startups and the developer community as a whole. Golang is an excellent language, designed with simplicity, maintainability and performance. Now is the best time to learn Go.
