This guide will help you set up Google OAuth authentication for your DataSpace application.

Prerequisites

• A Google Cloud Platform account

• Access to the Google Cloud Console

1

Create a Google Cloud Project

• Go to the Google Cloud Console

• Create a new project or select an existing one

• Note down your project ID

2

Enable Google+ API

• In the Google Cloud Console, go to "APIs & Services" > "Library"

• Search for "Google+ API" and enable it

• Alternatively, you can use the newer Google Identity API

3

Create OAuth 2.0 Credentials

• Go to "APIs & Services" > "Credentials"

• Click "Create Credentials" > "OAuth 2.0 Client IDs"

• Choose "Web application" as the application type

• Configure the OAuth consent screen if prompted

4

Configure OAuth Client

• Authorized JavaScript origins:

  • Add your frontend URL (e.g., https://yourdomain.com)

• Authorized redirect URIs:

  • Add your backend callback URL: https://yourdomain.com/api/auth/google-callback

5

Get Your Credentials

After creating the OAuth client, you'll get:

• Client ID (looks like: 123456789-abcdefg.apps.googleusercontent.com)

• Client Secret (looks like: GOCSPX-abcdefghijklmnopqrstuvwxyz)

6

Configure Environment Variables

Add the following environment variables to your application:

.env

GOOGLE_CLIENT_ID=your_google_client_id_here
GOOGLE_CLIENT_SECRET=your_google_client_secret_here
