Reach your computer from anywhere with Tailscale
  1. Install Tailscale on both devices, signed in to the same account.
  2. On your computer, run npm start -- --expose. It prints a pairing link and the computer's Tailscale address.
  3. Open that link here or scan its QR code — or type the address, like mymac.tailnet.ts.net, with the pairing code above.
