2024-06-20, Version 20.15.0 'Iron' (LTS), @marco-ippolito test_runner: support test plans It is now possible to count the number of assertions and subtests that are expected to run within a test. If the number of assertions and subtests that run does not match the expected count, the test will fail. test('top level test', t => { t.plan(2); t.assert.ok('some relevant assertion here'); t.subtest('su

By now you've noticed nodejs.org's fresh new look! We've taken great care in approaching this design with a nod to the past and look to the future. The site has many converging use cases, thousands of pages, and is a daily resource to many. The whole story had some dead ends and detours. But in the end it was a collective effort; coming to life with the contributions of over three dozen contributo

We're excited to announce the release of Node.js 21! Highlights include updates of the V8 JavaScript engine to 11.8, stable fetch and WebStreams, a new experimental flag to flip module defaults (--experimental-default-type), a built-in WebSocket client, many updates to our test runner, and more! Node.js 21 will replace Node.js 20 as our ‘Current’ release line when Node.js 20 enters long-term suppo

Notable changes built-in .env file support Starting from Node.js v20.6.0, Node.js supports .env files for configuring environment variables. Your configuration file should follow the INI file format, with each line containing a key-value pair for an environment variable. To initialize your Node.js application with predefined configurations, use the following CLI command: node --env-file=config.env

Notable Changes Mock Timers The new feature allows developers to write more reliable and predictable tests for time-dependent functionality. It includes MockTimers with the ability to mock setTimeout, setInterval from globals, node:timers, and node:timers/promises. The feature provides a simple API to advance time, enable specific timers, and release all timers. import assert from 'node:assert'; i

It allows developers to restrict access to specific resources during program execution, such as file system operations, child process spawning, and worker thread creation. The API exists behind a flag --experimental-permission which when enabled will restrict access to all available permissions. B

Notable changes Add support for externally shared js builtins By default Node.js is built so that all dependencies are bundled into the Node.js binary itself. Some Node.js distributions prefer to manage dependencies externally. There are existing build options that allow dependencies with native code to be externalized. This commit adds additional options so that dependencies with JavaScript code

Changing the End-of-Life Date for Node.js 16 to September 11th, 2023 Summary We are moving the End-of-Life date of Node.js 16 by seven months to coincide with the end of support of OpenSSL 1.1.1 on September 11th, 2023. Why? When we put together Node.js 16 the hope was that we would be able to include OpenSSL 3. Unfortunately, the timing of the releases did not allow that to be possible, and we re

Notable Changes Corepack Node.js now includes Corepack, a script that acts as a bridge between Node.js projects and the package managers they are intended to be used with during development. In practical terms, Corepack will let you use Yarn and pnpm without having to install them - just like what currently happens with npm, which is shipped in Node.js by default. Please head over to the Corepack
