Deploying to Firebase Hosting using CircleCI

Question

I'm trying to figure out how to deploy to Firebase Hosting using CircleCI. As far as I know, there is no way to setup deployment with an SSH key, so I'm trying to find a way of logging into Firebase during deployment and push the code. What I have tried so far is the following in my circle.yml:

// circle.yml
deployment:
  production:
    branch: circle-deploy
    commands:
      - npm install -g firebase-tools
      - firebase login | echo -e "${FIREBASE_EMAIL}\n${FIREBASE_PASSWORD}"
      - firebase deploy

However, I keep getting the following error and I'm not sure how to remedy it.

stream.js:94
      throw er; // Unhandled stream error in pipe.
            ^
Error: write EPIPE
    at errnoException (net.js:904:11)
at Object.afterWrite (net.js:720:19)

A small addition to the other answers above...

In order to avoid installing firebase-tools globally in circle ci on every build:

Modify your package.json file to include firebase-tools as a dev dependency like so:

npm install --save-dev firebase-tools

Then in your circle.yml file:

deployment:
  production:
    branch: master
    commands:
      - ./node_modules/.bin/firebase deploy --token=$FIREBASE_TOKEN --non-interactive

I just had to do this and there is a easier way

1. On your machine, you can get your access token by typing

   firebase login:ci
   

2. Save that token as an environment variable in circleci, $FIREBASE_TOKEN

3. For your deploy step, you can skip the login:

   deployment:
     production:
       branch: master
       commands:
         - firebase deploy --token=$FIREBASE_TOKEN --non-interactive
