Description
A RESTful API (Representational State Transfer) is a type of API that uses HTTP requests to access and manipulate data. It is designed to be stateless and follows a set of architectural principles, including:
Client-server architecture: The client and server are separated and communicate through a uniform interface.
Statelessness: The server does not store any client context, which allows for better scalability and reliability.
Cacheability: Responses from the server can be cached to improve performance.
Layered system: A client may not be aware of all the layers in the system, which allows for better encapsulation and modularity.
Uniform interface: The API should have a consistent interface that is easy to understand and use.
RESTful APIs typically use HTTP methods such as GET, POST, PUT, and DELETE to interact with resources, and they use URIs (Uniform Resource Identifiers) to identify resources.
Node.js is an open-source, cross-platform, runtime environment that allows developers to use JavaScript to build server-side applications. It uses an event-driven, non-blocking I/O model, which makes it lightweight and efficient.
Express.js is a web application framework for Node.js that provides a set of features for building web applications and APIs, such as routing, middleware, and error handling.
PostgreSQL is a powerful, open-source relational database management system that supports advanced SQL features, transactions, and concurrency control.
