Runtime Briefing — Node.js 22.0.0 Release

Executive briefing: The Node.js project promoted Node.js 22.0.0 on 23 April 2024, starting the current release phase that will graduate to LTS later in the year.

Feature overview

• V8 12.4. Ships JavaScript updates such as RegExp v flag support and performance improvements, affecting runtime behaviour.
• Stable WebSocket client. The built-in WebSocket API exits experimental status, enabling native realtime clients without external dependencies.
• Permission model. Ongoing work on --allow-fs-read and related flags advances the experimental security boundary story.

Adoption steps

• Extend CI matrices to exercise Node 22, monitoring for behaviour changes tied to the upgraded V8 engine.
• Evaluate WebSocket usage to determine whether native APIs can replace third-party clients and reduce supply-chain risk.
• Track the Node.js release schedule to plan the October 2024 LTS uplift and communicate timelines to product stakeholders.
