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.

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.
