Login with Twitch

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

Overview

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

• Create and configure a Twitch Application Twitch Developer Console
• Add your Twitch OAuth Consumer keys to your Supabase Project
• Add the login code to your Supabase JS Client App

Access your Twitch Developer account

• Go to dev.twitch.tv.
• Click on Log in with Twitch at the top right to log in.
• If you have not already enabled 2-Factor Authentication for your Twitch Account, you will need to do that at Twitch Security Settings before you can continue.

• Once logged in, go to the Twitch Developer Console.

Find your callback URL

<$Partial path="social_provider_setup.mdx" variables={{ "provider": "Twitch" }} />

Create a Twitch application

• Click on + Register Your Application at the top right.

• Enter the name of your application.
• Type or paste your OAuth Redirect URL (the callback URL from the previous step.)
• Select a category for your app.
• Check the CAPTCHA box and click Create.

Retrieve your Twitch OAuth client ID and client secret

• Click Manage at the right of your application entry in the list.

• Copy your Client ID.
• Click New Secret to create a new Client Secret.
• Copy your Client Secret.

Add your Twitch credentials into your Supabase project

<$Partial path="social_provider_settings_supabase.mdx" variables={{ "provider": "Twitch" }} />

Add login code to your client app

<Tabs scrollable size="small" type="underlined" defaultActiveId="js" queryGroup="language"

<$Partial path="create_client_snippet.mdx" />

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

import { createClient } from '@supabase/supabase-js'
const supabase = createClient('<your-project-url>', '<sb_publishable_... or anon key>')

// ---cut---
async function signInWithTwitch() {
  const { data, error } = await supabase.auth.signInWithOAuth({
    provider: 'twitch',
  })
}

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

Future<void> signInWithTwitch() async {
  await supabase.auth.signInWithOAuth(
    OAuthProvider.twitch,
    redirectTo: kIsWeb ? null : 'my.scheme://my-host', // Optionally set the redirect link to bring back the user via deeplink.
    authScreenLaunchMode:
        kIsWeb ? LaunchMode.platformDefault : LaunchMode.externalApplication, // Launch the auth screen in a new webview on mobile.
  );
}

When your user signs in, call signInWith(Provider) with Twitch as the Provider:

suspend fun signInWithTwitch() {
	supabase.auth.signInWith(Twitch)
}

<$Partial path="oauth_pkce_flow.mdx" />

<Tabs scrollable size="small" type="underlined" defaultActiveId="js" queryGroup="language"

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

import { createClient } from '@supabase/supabase-js'
const supabase = createClient('<your-project-url>', '<sb_publishable_... or anon key>')

// ---cut---
async function signOut() {
  const { error } = await supabase.auth.signOut()
}

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

Future<void> signOut() async {
  await supabase.auth.signOut();
}

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

suspend fun signOut() {
	supabase.auth.signOut()
}
