TODO

have expo project, want public testing url

expo has restricted loading of apps from public for ios, but here's a workaround that we use to let users test our apps when we do rapid-prototyping...

  1. create a github action to build the expo app with a unique app name for each PR, so you don't accidentally do anything to your production app and so comments are stamped to specific feature branches
  2. run npx expo publish --non-interactive
  3. look for the output url which looks like this:
    image: /uploads/ 📝 Manifest: https://exp.host/@***/***-pr-40/index.exp?sdkVersion=40.0.0 Learn more: https://expo.fyi/manifest-url
  4. Copy that url into a QR code generator like this one:
    http://goqr.me/#t=url
    Or use a cli script to do it at the end of the build process:
    https://www.npmjs.com/package/qrcode
    And then email it to the users that you want to test!
  5. Scan the code on your iPhone!
