Perhaps the most important feature for development workflows was the introduction of the native test runner. Before Node.js 18, setting up a testing environment required installing and configuring third-party libraries like Jest, Mocha, or Ava. The node:test module changed that.
Node.js 18 (codenamed "Hydrogen") was a watershed release in the Node.js ecosystem. Released in April 2022, it served as the Long Term Support (LTS) backbone for many applications through its active life.
As of today, Node.js 18 is in its , meaning it receives only critical bug fixes, security patches, and documentation updates—no new features. The “full” LTS cycle gave developers 3 years of stable support, making Node 18 one of the most enduring versions for production systems.

Alongside fetch, FormData is available globally, simplifying multi-part file uploads. Experimental support for the Web Streams API allows processing of data streams sequentially using modern web standards rather than the traditional, Node-specific streams module. 2. Built-In Test Runner Module

Maya thought of the sticker on her server rack. DO NOT RESTART. It felt less like instruction and more like a prayer. The “full” LTS cycle gave developers 3 years
If you are considering long-term support solutions for Node.js 18 or any other legacy version, the time to act is now. Post-EOL support options exist through partners of the OpenJS Foundation to ensure your legacy applications remain secure while you plan your full migration to a modern, supported version like Node.js 22 LTS. Review your infrastructure, plan your upgrade path, and move your projects to a secure and supported foundation.
If you’re moving to , you must check compatibility with your dependencies and native addons.
fetch() , Request , Response , and Headers are available globally.
To achieve a "full" setup of Node.js 18, developers had several reliable options:
