Step-by-Step: How to Upgrade to Node.js 24 LTS

Follow these steps to upgrade your Node.js backend safely:

Check your current version: Run node -v to see which Node.js version you currently use.
Backup your projects and environment: Ensure you have backups of code and dependencies.
Review compatibility: Check if your dependencies and frameworks support Node.js 24 LTS. For example, if you use Express, see the How to Install Express guide for recent version notes.
Download and install Node.js 24 LTS: Visit the official Node.js website (Official site), and choose the LTS installer for your OS.
Verify installation: After installation, run node -v again to confirm you now have version 24.x installed.
Test your applications thoroughly: Run your backend project and monitor for any issues or deprecations.
