Node.js is an open source server-side JavaScript runtime environment for building scalable and maintainable high-concurrency applications.
Main uses:
-
Web applications: Node.js is a popular choice for building dynamic, responsive web applications.
-
Backend Services: Node.js can be used to create backend services that handle logic and data storage to power mobile applications and websites.
-
Real-time applications: Node.js is ideal for building real-time applications, such as chat applications and game servers, because its asynchronous and non-blocking nature can handle a large number of concurrent connections.
-
Data stream processing: Node.js has excellent data stream processing capabilities, making it ideal for processing large amounts of data, such as log analysis and sensor data processing.
-
Microservices: Due to its lightweight and modularity, Node.js is ideal for building microservices, which are small, independently deployable, reusable components.
Main features:
-
Asynchronous and non-blocking: Node.js adopts an asynchronous and non-blocking programming model, allowing The application continues processing other tasks while waiting for I/O operations (such as network requests or database queries) to complete.
-
Single-threaded event loop: Node.js runs on a single thread and has an event loop, which can handle multiple concurrent operations at the same time, improving application performance.
-
Modularity: Node.js uses a modular architecture that allows developers to create and reuse pluggable code components.
-
Extensive ecosystem: Node.js has a large number of open source libraries and modules covering various functions such as database connections, authentication and web frameworks.
