A useful and handy aspect of being a modern web developer is knowing how to work with APIs to facilitate communication between different software systems. In this course, youll learn how to create your own RESTful API in a Node. js environment running on an Express server and utilizing a PostgreSQL database. We will use Postman as our API client to interact with the API Server. REST stands for Representational State Transfer and defines a set of standards for web services. It is an architectural style as well as an approach for communications purposes that is often used in various web services development. An API is an interface that different software programs use to communicate with each other. RESTful API is an API that conforms to the REST architectural style and constraints. REST systems are stateless, scalable, cacheable, and have a uniform interface. RESTful APIs most commonly utilize HTTP requests. Four of the most common HTTP methods are: GET, POST, PUT, and DELETE, which are the methods by which a developer can create a CRUD system create, read, update, delete.
