RESTful web services RESTful is a popular architectural style for designing networked applications, particularly the Web services. REST is an acronym of Representational State Transfer, a paradigm described by Roy Fielding in his PhD dissertation in 2000. RESTful is a design of principles and constraints to be used for communicating between the client-side and server-side in a simple, scalable, stateless way. The reason RESTful services provide the foundation for contemporary web, mobile and cloud applications is because they are lightweight, versatile, and can be mashed up with a variety of technologies. https://gitea.mpc-web.jp/gurpreet5688/bdfsfs/issues/1

At heart, RESTful architecture is about resources (as opposed to methods). Resource can be anything including the user, product, order or a document which can be accessed through the web. Every resource has a unique URI for its identification. Instead of calling methods, clients access these resources with standard HTTP methods. This is a good approach for communication and it enables systems written in different programming languages to connect with one another without problems.

Origins and Importance of REST

REST was created to solve the problems associated with these earlier web service models including “heavyweight” SOAP that was (and is) slow, and difficult to use. REST, on the contrary, is a simpler approach to web services — it’s easier because it builds on existing Web standards like HTTP and URLs and MIME types. RESTful design promotes loose coupling between the client and server components of a system, such that changes made to one part of the system do not generate additional work for another.

The power of REST architecture is its scalability and performance. As REST services are stateless, servers will not require client session state. This can help to minimize the server load and applications can easily scale; particularly with distributed/multi cloud environment. Nowadays, REST is the most popular way to develop APIs that are consumed by social media applications, e-commerce websites and in house enterprises systems.

Core Principles of RESTful Architecture

RESTful design is based on a series of constraints about the way systems are suppose to be designed. These aren't optional; they are what it means for a service to truly be RESTful. There is a number of basic principles, such as the one about separation of client-server. In this pattern, the client takes care of the user interface and the server manages data processing and storage, as well as business logic. This implies that each party can evolve independently.

Another key principle is statelessness. In RESTful design a client request should include all necessary data the server needs to fulfill it. No client state is maintained server side between requests. It also makes the system more reliable and simpler to scale since no server instance needs to remember anything when it interacts with a client. full stack developer training

RESTful architecture also emphasizes cacheability. The server’s answer should clearly indicate whether it is cacheable or not. Good caching will help you deliver better performance, time to response and less unnecessary arsenal. At its best, caching makes RESTful services very efficient.
