Efficient handling of concurrent connections for scalable applications.
What is Node.js?
Node.js is commonly used for building backend services and APIs for websites. It allows developers to use JavaScript on the server side, which can be beneficial for teams that are already familiar with JavaScript for frontend development.
Key features and concepts of Node.js includes:
- Server-Side Logic: Node.js enables developers to write server-side logic using JavaScript, handling tasks such as database operations, authentication, and business logic.
- Scalability: Node.js is known for its scalability due to its non-blocking, event-driven architecture. This makes it suitable for handling a large number of simultaneous connections efficiently.
- Real-Time Applications: It's particularly well-suited for real-time applications like chat applications, online gaming, collaborative tools, and live streaming, where immediate communication between client and server is crucial.
- APIs: Many websites use Node.js to create RESTful APIs that frontend applications (built using frameworks like React, Angular, or Vue.js) can communicate with to fetch data and perform actions on the server.
- Microservices: Node.js is often chosen for building microservices architectures due to its lightweight nature and ability to handle asynchronous operations efficiently.
- Frameworks and Libraries: There are popular frameworks and libraries in the Node.js ecosystem like Express.js, Koa.js, and NestJS that streamline the development of web applications and APIs, providing features such as routing, middleware support, and more.
