Node.js is a popular open-source JavaScript runtime environment that allows developers to build scalable and high-performance web applications. One of the key strengths of Node.js is its ability to build APIs quickly and efficiently. APIs, or Application Programming Interfaces, allow different systems to communicate with each other, enabling data exchange and other operations. Building robust APIs with Node.js requires an understanding of RESTful architecture, which is a widely adopted standard for creating APIs. RESTful APIs provide a standardized way to expose data and functionality over the web using a set of HTTP methods such as GET, POST, PUT, and DELETE. To build a robust Node.js API, developers must choose an appropriate framework and set up a development environment. They should also handle errors and exceptions, implement authentication and authorization, and use middleware to enhance the functionality of the API. Writing test cases, documenting the API using tools such as Swa...
