What is Node.js?
Node.js is a powerful JavaScript runtime built on Chrome’s V8 JavaScript engine. It allows you to run JavaScript code on the server side, enabling you to build scalable network applications with ease. Node.js uses an event-driven, non-blocking I/O model which makes it lightweight and efficient.
Features of Node.js:
- Fast and efficient: Node.js is known for its speed and efficiency, making it a great choice for building real-time applications such as chat applications, online gaming, and collaboration tools.
- Scalable: Node.js is designed to handle a large number of concurrent connections, making it a great choice for building scalable network applications.
- Extensive library: Node.js has a rich library of modules that can be easily integrated into your application, making it easy to build complex functionality without reinventing the wheel.
- Asynchronous and event-driven: Node.js uses an asynchronous, event-driven programming model which allows for handling a large number of requests without blocking the execution of code.
Use Cases for Node.js:
Node.js is commonly used for building:
- APIs and backend services
- Real-time web applications
- Streaming applications
- Microservices architecture
- IoT applications
