Login with GitLab

To enable GitLab Auth for your project, you need to set up a GitLab OAuth application and add the application credentials to your Supabase Dashboard.

Overview#

Setting up GitLab logins for your application consists of 3 parts:

The next step requires a callback URL, which looks like this:

https://<project-ref>.supabase.co/auth/v1/callback

Go to your Supabase Project Dashboard
Click on the Authentication icon in the left sidebar
Click on Providers under the Configuration section
Click on GitLab from the accordion list to expand and you'll find your Redirect URL, you can click Copy to copy it to the clipboard

Click on your profile logo (avatar) in the top-right corner.
Select Edit profile.
In the left sidebar, select Applications.
Enter the name of the application.
In the Redirect URI box, type the callback URL of your app.
Check the box next to Confidential (make sure it is checked).
Check the scope named read_user (this is the only required scope).
Click Save Application at the bottom.
Copy and save your Application ID (client_id) and Secret (client_secret) which you'll need later.

Go to your Supabase Project Dashboard
In the left sidebar, click the Authentication icon (near the top)
Click on Providers under the Configuration section
Click on GitLab from the accordion list to expand and turn GitLab Enabled to ON
Enter your GitLab Client ID and GitLab Client Secret saved in the previous step
Click Save

When your user signs in, call signInWithOAuth() with gitlab as the provider:

async function signInWithGitLab() {
  const { data, error } = await supabase.auth.signInWithOAuth({
    provider: 'gitlab',
  })
}

When your user signs out, call signOut() to remove them from the browser session and any objects from localStorage:

async function signout() {
  const { error } = await supabase.auth.signOut()
}
