Create a new project

Get project configs

Update firebase.config.js with what your project gave you

vi src/firebase.config.js

It should look something like this

export default {

  authDomain: 'your-app-domain.firebaseapp.io',
  databaseURL: 'https://your-firebase-database-url.firebaseio.com',
}

firebase login
firebase init

• select project name that you created
• select default for other options

Get an admin credential file

• Go to "Project Setting" on firebase console.
• Select "SERVICE ACCOUNTS" tab
• Click on "GENERATE NEW PRIVATE KEY" at the bottom
• It will download a creds json file
• Copy that file to root folder of your project and rename it as 'firebase-admin.json'

For Mac user

cp ~/Downloads/[downloaded file name].json ./firebase-admin.json

Apply new rules for firebase database

Update ./database.rules.json as you needed

And deploy it

firebase deploy --only database

Run tests

Run test once

yarn test-once

Run tests any time *.js file updates (watch and run tests)

yarn test

Run tests as an authenticated user

Pick a UID from firebase console > Authentication > USERS

Put the UID to the test

vi src/auth.test.js

describe('Authenticated firebase', () => {
  let authedFirebase
  const UID = 'vl7GjxgIRre1sD0ftesttesttesttest'
...
...

Default tests will be successful, if your database has /user/joshua available
