Sample Express app that integrates with Google Identity Platform

This is a sample app that integrates with Google Identity Platform doing a OAuth2 implicit authentication flow with the result being an Open Id Connected Id Token. The token can then be validated against a service using an Express authentication middleware.

Setup

First register a OAuth2 client:

1. Go to https://console.cloud.google.com/apis/credentials
2. Click "Create credentials"->"OAuth Client ID"
3. Select "Web application"
4. Add "Authorised JavaScript origins", fx. http://localhost:3000 for testing this app
5. Add "Authorised redirect URIs", fx. http://localhost:3000/index.html for testing this app

Run sample application

node index.js '<OAuth Client ID>'
