What are the core modules of nodejs

Node.js provides a variety of core modules for handling common tasks such as: HTTP processing (http) File system operations (fs) Path operations (path) Operating system interaction (os) Encryption and hashing (crypto) Child process management (child_process) Time management (timers) Utility functions (util) Event monitoring (events) Stream management (stream)

The core module of Node.js

Node.js is an event-driven server-side JavaScript runtime environment. It provides a set of built-in core modules that provide basic functionality for handling various tasks.

The most commonly used core modules:

• http: Handle HTTP requests and responses.
• fs: Interact with the file system.
• path: Operation file and directory paths.
• os: Interact with the operating system.
• crypto: Provides encryption and hashing functions.
• child_process: Create and manage child processes.
• timers: Plan and control time.
• util: Provides various utility functions.
• events: Create and manage event listeners.
• stream: Manage data stream.

Other core modules:

In addition to the most commonly used modules mentioned above, Node.js also provides many other core modules, including:

• async_hooks: Track asynchronous operations.
• buffer: Process binary data.
• cluster: Create and manage multi-process applications.
• console: Provides simple output and debugging tools.
• dgram: Send and receive UDP datagrams.
• dns: Resolve domain name.
• domain: Error handling and event management.
• fs/promises: Provides an asynchronous version of the fs module.
• inspector: Used for remote debugging and analysis.
• module: Interact with the module system.
• net: Create and manage TCP and UDP servers and clients.
• readline: Read data from the input stream.
• repl: An interactive JavaScript shell.
• tls: Handles encrypted TLS/SSL connections.
• tty: Manage terminal input and output.
• url: Parse and manipulate URLs.
• v8: Interact with the V8 JavaScript engine.
• worker_threads: Create and manage multi-threaded applications.

These core modules provide the basic functionality of a Node.js application and can be easily extended to meet various needs.
