Setup Instructions

1. Update the value of application in appengine-web.xml to the app ID you have registered in the App Engine admin console and would like to use to host your instance of this sample.

2. Optional step: These sub steps are not required but you need this if you want to have auth protected methods.

   1. Update the values:

      1. SERVICE_ACCOUNT_CLIENT_ID | (From a Service Acc on GCP)
      2. WEB_CLIENT_ID | (Create an OAuth acc on GCP to get credentials)

      in src/main/java/${packageInPathFormat}/Constants.java to reflect the respective client IDs you have registered in the [APIs Console][6].

   2. Update the values:

      1. CLIENT_ID | same used in WEB_CLIENT_ID

      in src/main/webapp/modules/auth/index.js to reflect the respective client IDs you have registered in the [APIs Console][6].

   3. You also need to supply the web client ID you have registered in the APIs Console to your client of choice (web, Android, iOS).

3. Run the application with mvn appengine:run, and ensure it's running by visiting your local server's api explorer's address (by default localhost:8080/_ah/api/explorer.)

4. Deploy your application to Google App Engine with

   $ mvn appengine:deploy
