Apollo server 2.0

This project is a good starting point for all the people that want to have apollo-server 2.0 ready to use. It integrates:

  • queries
  • mutations
  • subscriptions (real-time data)
  • authentication and authorisation (using google sign-on as provider server)
  • schema stitching
  • mongo db
  • logger (it will create a file error.log and write on it in case of error - to change the level edit common/util/logger.ts lines 12, 13, 14 )

Installation:

Environment

In the root folder is available a file called .env. It contains all the configuration environment for:

  1. mongodb
  2. google-sign-in as identity server for authentication and authorisation. More info available at http://www.dzurico.com/apollo-server-2-0-auth-with-google-signin/

available commands

  • test environment: npm run dev (it will automatically rerun your code all the time you save and will check for tslint errors and formatting style errors.)
  • production environment: npm run prod
