Integrated Google OAuth 2.0

Rishi Raj Jain

LaunchFa.st comes with baked-in Google OAuth 2.0 APIs to help you authenticate your users using Google.

Google OAuth 2.0 Authentication method uses Google APIs to communicate (all server-side) and creates a cookie with a signed session, ensuring that your user data is secure and only present for the logged in sessions.

Here’s the whole flow:

  • The /api/auth/google built-in endpoint creates an authorization URL using Google APIs.
  • The users authenticate with their Google account.
  • The /api/auth/callback/google built-in endpoint takes care of retrieving the user information using Google APIs.
  • The user information is then encoded into a cookie and set on the root path making it available on each outgoing request from the session.

With the SignInWithGoogle component, here’s what you just need to do with LaunchFa.st to authentication users with Google:

random.astro
---
import SignInWithGoogle from '@/components/Sign-In-With-Google.astro' // [!code ++] // [!code focus]
// ...
---
<SignInWithGoogle /> // [!code ++] // [!code focus]

But you do not even need to do that, as the signin.astro contains all the UI that you need for accepting sign in from your users with all the methods: Google, Twitter and Credentials.
