Worker threads | Node.js v21.1.0 Documentation
Source Code: lib/worker_threads.js The node:worker_threads module enables the use of threads that execute JavaScript in parallel. To access it: const worker = require('node:worker_threads'); copy Workers (threads) are useful for performing CPU-intensive JavaScript operations. They do not help much with I/O-intensive work. The Node.js built-in asynchronous I/O operations are more efficient than Wor
Backpressuring in Streams | Node.js
Backpressuring in Streams There is a general problem that occurs during data handling called backpressure and describes a buildup of data behind a buffer during data transfer. When the receiving end of the transfer has complex operations, or is slower for whatever reason, there is a tendency for data from the incoming source to accumulate, like a clog. To solve this problem, there must be a delega

Node.js — The Node.js Event Loop
The Node.js Event Loop What is the Event Loop? The event loop is what allows Node.js to perform non-blocking I/O operations — despite the fact that JavaScript is single-threaded — by offloading operations to the system kernel whenever possible. Since most modern kernels are multi-threaded, they can handle multiple operations executing in the background. When one of these operations completes, the

Source Code: lib/https.js HTTPS is the HTTP protocol over TLS/SSL. In Node.js this is implemented as a separate module. Determining if crypto support is unavailable# It is possible for Node.js to be built without including support for the node:crypto module. In such cases, attempting to import from https or calling require('node:https') will result in an error being thrown. When using CommonJS, th

Source Code: lib/cluster.js Clusters of Node.js processes can be used to run multiple instances of Node.js that can distribute workloads among their application threads. When process isolation is not needed, use the worker_threads module instead, which allows running multiple application threads within a single Node.js instance.

Node.js — About Node.js®
About Node.js® As an asynchronous event-driven JavaScript runtime, Node.js is designed to build scalable network applications. In the following "hello world" example, many connections can be handled concurrently. Upon each connection, the callback is fired, but if there is no work to be done, Node.js will sleep. const { createServer } = require('node:http'); const hostname = '127.0.0.1'; const por

Modules Node.js v0.12.18 Manual & Documentation
Modules# Stability: 5 - Locked Node has a simple module loading system. In Node, files and modules are in one-to-one correspondence. As an example, foo.js loads the module circle.js in the same directory. The contents of foo.js: var circle = require('./circle.js'); console.log( 'The area of a circle of radius 4 is ' + circle.area(4)); The contents of circle.js: var PI = Math.PI; exports.area = fun
Assert | Node.js v22.5.0 Documentation
In strict assertion mode, non-strict methods behave like their corresponding strict methods. For example, assert.deepEqual() will behave like assert.deepStrictEqual(). In strict assertion mode, error messages for objects display a diff. In legacy assertion mode, error messages for objects display the objects, often truncated. To use strict assertion mode: import { strict as assert } from 'node:ass

Modules | Node.js v10.12.0 Documentation
CommonJS modules are the original way to package JavaScript code for Node.js. Node.js also supports the ECMAScript modules standard used by browsers and other JavaScript runtimes. In Node.js, each file is treated as a separate module. For example, consider a file named foo.js: const circle = require('./circle.js'); console.log(`The area of a circle of radius 4 is ${circle.area(4)}`); copy On the f
