In LaunchYourApp, we use Magic Link with Supabase and Expo. Follow these steps to configure Magic Link:
1

Configure app.json

Ensure your app.json has the slug and scheme configured. LaunchYourApp includes this by default, but remember to change it to the name of your application:
"slug": "launch-your-app",
"scheme": "exp+launch-your-app",
2

Supabase Setup

  1. Open your Supabase project.
  2. Go to the “Authentication” tab.
  3. Click on the “URL Configuration” tab.
You should see a screen like this:
  1. In the Site Url field, enter the scheme of your application that we configured in the previous step, and include :// at the end.
  2. In the Redirect URLs field, include these three URLs:
  • http://192.168.0.3:8081 - This is the URL that your application usually runs in development mode, but you can change it to your local IP.
  • http://localhost:8081 - This is another URL that your application usually runs in development mode. Again, you can change it to your localhost Port and IP.
  • exp+launch-your-app://confirm-magic-link - This is the URL that your application will open when the user clicks on the Magic Link. Change launch-your-app to the scheme of your application.
