Quickly get going with a server hooked up using Google OAuth, PassportJS and a mongoDB schema.

Express Server App w/ Google OAuth

Usage: An easy to use server with google auth, ready to be wired up to any development app.

How to get setup:

1. npm install

2. create a folder -> config

3. in the config folder create a file and name it keys.js

4. in keys.js add this code

   module.exports = { googleClientID: '', googleClientSecret: '', mongoURI: '', cookieKey: 'WHATEVER_YOU_WANT_YOUR_COOKIE_TO_BE', };

5. create a google cloud project and give it a name.

   • in the menu go to APIs & Services -> OAuth Consent Screen; select external
   • give it an application name and save
   • on the left go to credentials; click create credentials at the top; select OAuth option
   • this is a web app so select web app
   • authorized javascript origins : http://localhost:5000
   • authorized redirect: http://localhost:5000/auth/google/callback
   • press create and then copy your clientID and clientSecret into the keys.js file

6. create your mongoDB

   • set up a cluster
   • name your cluster and create
   • after a minute your cluster will be up and you will click connect in the sandbox
   • click Add your current IP address
   • in the next section fill in a username and password (copy your password into keys.js) and click create mongoDB user button
   • then click choose a connection method and select connect your application
   • copy the connection string into keys.js and paste it into the mongoURI

7. You're all set! Save your keys.js file. In your terminal run npm run dev and go to http://localhost:5000/auth/google to start the authentication flow. If you get "Cannot GET auth/google/callback" then it worked! check by going to /api/current_user
