Travis CI integration

Which Google Cloud services work with Firebase? - #AskFirebase - 2.43min in

Firebase CLI, can give you a key for continuous integration like travis. See https://docs.travis-ci.com/user/deployment/firebase/

firebase login:ci

In travis config, can add ENV FIREBASE_TOKEN.

In .travis.yml

...
install
- nom install -g firebase-tooltos
after_success:
- firebase deploy --token $FIREBASE_TOKEN
...

Travis CLI

Alternatively, after you generate the Firebase token from running the login:ci command, install travis CLI and do:

travis encrypt "<FIREBASE_TOKEN>" --add
# This command may generate a warning ("If you tried to pass the name of the repository as the first argument, you probably won't get the results you wanted"). You can ignore it.

This will add the encrypted secure token to your Travis config file.

.env file with secure tokens

If you have a .env file that stores all your configuration, you should also do this:

travis encrypt-file .env --add

This will create an .env.enc file, and the step to decode is added to your Travis config file. You should commit the .env.enc to your Github repository.

Note: that there is a known bug with Travis version 1.8.11 , and you would need to install 1.8.10 instead.

Deploying specific services (hosting, functions, firestore)

If you want to deploy only to specific services - e.g. hosting or otherwise - you need to get the edge version of the dpl tool in Travis. This just means you need to add the following to your config:

deploy:
provider: firebase
edge:
branch: master
...

This would then allow you to use Firebase CLI's only option:

deploy:
provider: firebase
edge:
branch: master
project: dev # the default project will be selected from firebase.json
only: hosting:digital-paper-edit-dev
.travis.yml
language: node_js
node_js:
