![]() It allows for the separation of front-end code (representation and possible UI-related processing of the information) from the server-side code, which should take care of storage and server-side processing of the data. This offers a great deal of flexibility when developing both systems without them affecting each other.Īccording to Fernando Doglio in REST API Development with Node.js: The main principle behind this constraint is the separation of concerns. The client on the other hand knows about the API endpoints and calls them in order to get a service done and gets the response. The API endpoints are usually published in an API documentation, using tools like Swagger. The server contains the server code and exposes the endpoints to the public via URL. The server should not rely on the client to function, and the client should not depend on the server. This constraint requires that the client and server must function independently. A resource represents a single state in the server and it can be accessed via a common interface, it can then be fetched or manipulated through the HTTP verbs: GET, POST, DELETE and PUT.Ī system is deemed RESTful if it meets the following constraints: Client-Server REST APIs provide these web services in what is called a resource. REST simply provides guidelines for high-level architecture implementation on how the backend data will be available to the client via JSON/XML messaging format.Īn API uses the REST guidelines to provide web services that are ready for consumption. REST uses HTTP protocol for communication and it is widely used in web applications. It all began with Fielding in 2000, who sort to develop a unique way of standardizing client-server communication. ![]() REST (short for REpresentational State Transfer) is an architectural style defined to help create and organize distributed systems. So we will bring both REST and gRPC to light in this post to explain the benefits and how they work. gRPC is rarely ever used or brought up, so gRPC becomes unknown and it is dug up when devs begin to delve deep into HTTP communication. Most tutorials on programming languages or frameworks like Reactjs, Angular, PHP, etc use HTTP when teaching about client-server communication. So by default, new devs become acquainted with REST. Most developers are very familiar with REST, this is because REST is majorly used in the world, and also it is used in beginner tutorials when teaching about HTTP programming. In this article, we will look at a high-level approach between two HTTP communication protocols and API design gRPC and REST. ![]() Learn when it's best to use REST and when you should go for gRPC. I think you should choose the one according to your use-case.
