Node.js runs the prototypes and web apps you'll build with Claude Code. (The native installer means Claude Code itself doesn't need it, but your projects will.) If you've never installed it before, that's fine, most designers haven't. You'll either confirm it's already there or grab it in two minutes.
Check if You Already Have Node.js
1
On Mac
- Press Command + Space, type "Terminal", and hit Enter
- Paste this and press Enter: node --version
- If you see a version number, you're done with this section!
2
On Windows
- Click the Windows logo, type "Command Prompt", and hit Enter
- Paste this and press Enter: node --version
- If you see a version number, skip to the next lesson!
Install Node.js (If You Need It)
1
Go to nodejs.org
Visit the official Node.js website
2
Download the "LTS" version
This is the stable, recommended version for production use
3
Run the installer and follow the instructions
Just click "Next" on everything - the defaults are perfect for you
4
Verify the installation
Open Terminal/Command Prompt again and run node --version to confirm it worked
Node.js is in place
- Checked whether Node.js was already installed
- Downloaded the LTS version from nodejs.org if needed
- Verified the install with node --version
One more install and your environment is ready. Next: Claude Code itself.
