REST Developers

REST relies on using the HTTP protocol, the fundamental protocol of the World Wide Web, for all key data operations – creating, reading, updating and deleting.

There are five key constraints to the REST style of design:

• Stateless – requests themselves contain the state necessary to handle requests
• Uniform interface – anything that can be done in third party web services, can also be achieved with REST architecture
• Cacheable – caching is an important feature of the World Wide Web, and API-generated data needs to be defined as cacheable or not, in order to avoid serving old data through the API
• Client-Server – REST allows servers to be built simpler, and to scale more effectively, because the Uniform Interface separates servers from clients, meaning that server issues (like data storage) do not affect the end-point client
• Layered – it means that REST APIs should be layered in a way that the client can’t tell whether it’s connecting with the end server, or a different server layer, which can greatly enhance security

REST APIs have become a key part of web development, so knowing how to use, integrate, and develop REST APIs is a very important skills for developers to have, especially on the back-end side of your project.
