Firenotes: Firebase Authentication on Google App Engine

A simple note-taking application that stores users' notes in their own personal notebooks separated by a unique user ID generated by Firebase. Uses Firebase Authentication, Google App Engine, and Google Cloud Datastore.

This sample is used on the following documentation page:

https://cloud.google.com/appengine/docs/python/authenticating-users-firebase-appengine/

You'll need to have Python 2.7 and the Google Cloud SDK installed and initialized to an App Engine project before running the code in this sample.

Setup

1. Clone this repo:

    git clone https://github.com/GoogleCloudPlatform/python-docs-samples.git
   

2. Navigate to the directory that contains the sample code:

    cd python-docs-samples/appengine/standard/firebase/firenotes
   

3. Within a virtualenv, install the dependencies to the backend service:

    pip install -r requirements.txt -t lib
   

4. Add Firebase to your app.

5. Add your Firebase project ID to the backend’s app.yaml file as an environment variable.

6. Select which providers you want to enable. Delete the providers from main.js that you do no want to offer. Enable the providers you chose to keep in the Firebase console under Auth > Sign-in Method > Sign-in providers.

7. In the Firebase console, under OAuth redirect domains, click Add Domain and enter the domain of your app on App Engine: [PROJECT_ID].appspot.com. Do not include "http://" before the domain name.

Run Locally

1. Add the backend host URL to main.js: http://localhost:8081.

2. Navigate to the root directory of the application and start the development server with the following command:

    dev_appserver.py frontend/app.yaml backend/app.yaml
   

3. Visit http://locahost:8080/ in a web browser.

Deploy

1. Change the backend host URL in main.js to https://backend-dot-[PROJECT_ID].appspot.com.

2. Deploy the application using the Cloud SDK command-line interface:

    gcloud app deploy backend/index.yaml frontend/app.yaml backend/app.yaml
   

   The Cloud Datastore indexes can take a while to update, so the application might not be fully functional immediately after deployment.

3. View the application live at https://[PROJECT_ID].appspot.com.
