Setting up Git Credential Manager (Windows) with OAuth2 client secret

To set up GCM for Windows with remote repo generic OAuth2/OIDC authentication, you can follow these steps:

1. Install the Google Cloud Messaging (GCM) libraries:

   npm install --save @google-cloud/gcm
   

2. Set up a service account on Google Cloud Platform (GCP) with the necessary permissions:

   • Go to the GCP Console (https://console.cloud.google.com/)
   • Navigate to IAM & Admin > Service Accounts
   • Create a new service account and grant it the "Cloud Messaging Sender" role
   • Download the JSON key file for the service account

3. Import the JSON key file into your Node.js project:

   const {Client} = require('@google-cloud/gcm');
   const client = new Client({keyFilename: 'path/to/your-service-account-key.json'});
   

4. Configure OAuth2/OIDC authentication:

   • Set up an OAuth2/OIDC provider (e.g., Auth0, Okta, or Google) and obtain the necessary client ID, client secret, and authorization URLs
   • Implement the authentication flow in your application, exchanging authorization codes for access tokens

5. Use the access token to send messages with GCM:

   async function sendMessage(registrationTokens, message) {
     const response = await client.send(registrationTokens, message);
     console.log(`Successfully sent message: ${response.result.length} messages sent!`);
   }
   
   // Example usage
   const registrationTokens = ['registration_token_1', 'registration_token_2'];
   const message = {
     notification: {
       title: 'Title of your notification',
       body: 'Body of your notification',
     },
   };
   sendMessage(registrationTokens, message);
