An Introduction to REST

Explore the fundamental principles of RESTful service architecture, including client-server design, statelessness, and HTTP methods like GET, POST, PUT, PATCH, and DELETE. Understand key HTTP status codes and learn how to build a RESTful client in Go that interacts with APIs and integrates with a MySQL database to handle data effectively.

Principles of RESTful service architecture

Most modern web applications work by exposing their APIs and allowing clients to use these APIs to interact and communicate with them. Although REST is not tied to HTTP, most web services use HTTP as their underlying protocol. Additionally, although REST can work with any data format, usually REST means JSON over HTTP because most of the time, data is exchanged in JSON format in RESTful services. There are also times when data is exchanged in plain text format, usually when the exchanged data is simple, and there is no need for using JSON records.

Due to the way a RESTful service works, it should have an architecture that follows the following principles:

  • Client-server design

  • Stateless implementation—this means that each interaction does not depend on others

  • Cacheable ...
