REST APIs

REST stands for REpresentational State Transfer, and API means Application Programming Interface

REpresentational State Transfer, or REST, is a set of constraints that ensure a scalable, fault-tolerant and easily extendible system

An Overview

• It fits in microservice architecture for connecting them together

• Every microservice has an endpoint, which can be accessed by other services

• Generally response is shared in json format (most commonly used, XML is another format)

• It uses HTTP as the standard protocal for sharing resource between client and server

"Microservices - also known as the microservice architecture - is an architectural style that structures an application as a collection of services that are. Highly maintainable and testable. Loosely coupled. Independently deployable. Organized around business capabilities."

Properties

• Uniform Interface: service is resource based (different endpoint for each resource), self descriptive, and manipulation of data is allowed through representation

• Stateless: no need to explicitly store state, everything should be handled through links or input variables

• Cachable: web-driver stores it

• Client server: client code and back-end server could be separate
