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:

• Create and configure a GitLab Application on GitLab
• Add your GitLab Application keys to your Supabase Project
• Add the login code to your Supabase JS Client App

Access your GitLab account#

• Go to gitlab.com.
• Click on Login at the top right to log in.

Find your callback URL#

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

Create your GitLab Application#

• 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.

Add your GitLab credentials into your Supabase Project#

• 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

Add login code to your client app#

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()
}
