Flask App accessed by Vue App OAuth Demo

Server side code running an authenticated API and a browser based client. In practice these will be two separate repositories. They are presented together here for convenience.

Flask App (API)

The flask app has resources that require auth.

• Authenticates user via oauth2
• Tracks logged in user via session
• Runs on localhost:5000

Vue App (UI)

The Vue client has visualizations for the protected resources.

• Has callback route that handles talking to api callback endpoint.
• Displays logged in status
• Runs on localhost:8080

Configure

1. Create project in Google Cloud Platform
2. Configure Web application credentials
   • Authorized JavaScript origins:
     • http://127.0.0.1:8080
     • http://localhost:8080
     • http://127.0.0.1:5000
   • Authorized redirect URIs:
     • http://127.0.0.1:5000/auth_callback
3. Download client_secret json, move to client_secret.json in flaskapp dir.
4. Create client_config.js containing client_id in vue_ui/src dir.

Run

1. Start flask app
2. Start serving Vue app
3. Open Vue app in browser

Notes

• Server side API has endpoints for both web server application flow and server-side flow.
• Browsing API uses web server application flow similar to existing work.
• Vue UI uses server-side flow by initiating auth and passing one-time code to API.
