Multiple environments with Firebase Hosting

Cover image

More often than not, a project requires multiple environments to deploy to. What I commonly use on top of my development environment is a staging environment and of course, a production environment.

I recently started using Firebase Hosting to host my Vue.js applications and I needed to be able to configure hosting so I could easily deploy to any environment easily. Let’s see an example.

Create a Vue.js project

For this example, we are going to generate a basic Vue.js application using the Vue CLI.

To install Vue CLI, run this command:

$ npm install -g @vue/cli

Then generate a project, we’ll call this one firebase-hosting:

$ vue create firebase-hosting

Select the default preset and pick npm as a dependency manager.

The Vue CLI is going to create the project and install the dependencies, as well as initializing a Git repository.

You can now go to the firebase-hosting directory and run the project:

$ cd firebase-hosting && npm run serve

Visit http://localhost:8080 and you should see this:

A brand new Vue.js project

Setup Firebase

Note: For this example, we will simply initialize Firebase for hosting. If you would like to know how to use the other features that Firebase can offer with Vue.js, stay tuned for future posts.

To initialize Firebase Hosting within your project, you need to install the firebase-tools package globally and log in:

$ npm install -g firebase-tools
$ firebase login

To support multiple environments with Firebase Hosting, multiple options are available:

  • Use two different sites: and
  • Use two completely different projects

I prefer the second approach, as we usually want to also use the other features that Firebase offers and it’s usually a good thing to keep things separated.

Then run the initialization command within your project’s directory:

$ firebase init hosting

Then answer the following:

? Please select an option: (Use arrow keys): Create a new project
? Please specify a unique project id: firebase-hosting-vue-staging
? What would you like to call your project? (defaults to your project ID) (): use default
? What do you want to use as your public directory? (public): dist
? Configure as a single-page app (rewrite all urls to /index.html)?: y

Your project should now be configured within Firebase. You can double-check by running:

$ firebase projects:list

This will list the projects available in the command-line, where you should see your project name and (current) should be written next to it.

To create the production environment, we will use the projects:create command:

$ firebase projects:create firebase-hosting-vue

Now you that we have the staging and production environments ready, you can add them using:

$ firebase use --add

Select firebase-hosting-vue-staging and type staging as an alias.

Repeat the process for the production project, use production as an alias.

This information is stored in a .firebaserc file at the root of your project:

  "projects": {
    "default": "firebase-hosting-vue-staging",
    "staging": "firebase-hosting-vue-staging",
    "production": "firebase-hosting-vue"

Deploy to Firebase Hosting

Now to deploy, we can specify the project withing the command:

$ firebase deploy -P staging
$ firebase deploy -P production
