Pre-flight

Do this before the day — five minutes, once per team. Means nobody's first hour is spent debugging a Node install on a locked-down laptop.

What you need​

  • Node.js 18+ — nodejs.org
  • A terminal — Terminal/iTerm on macOS, PowerShell/cmd on Windows
  • A Cloudflare account — free is fine, sign up here if you don't have one. You'll join the event's shared account separately at Sign Up.

Nothing to install globally — everything below runs through npx.

Verify script​

Same command on every platform:

node -v
npx wrangler --version
npx wrangler login
npx wrangler whoami
  1. node -v → v18.x.x or higher
  2. npx wrangler --version → confirms npx works and you have npm access
  3. npx wrangler login → opens a browser tab to authorize. Approve it.
  4. npx wrangler whoami → prints your email. See it? You're done.
If something doesn't work

Usually a corporate laptop blocking the npm registry or the wrangler login browser pop-up. Try a personal laptop or phone hotspot, or ask a host before the day — much easier to fix with five days' notice than five minutes before the talk starts.
