How to deploy Nuxt to Firebase Hosting with Nuxt Nitro

• Support for serverless SSR build
• Minimal configuration required

Setup

Nitro supports Firebase Hosting with Cloud Functions out of the box.

Note: You will need to be on the Blaze plan in order to use Nitro with Cloud Functions.

Using Nitro

If you don't already have a firebase.json in your root directory, Nitro will create one the first time you run it. All you will need to do is edit this to replace <your_project_id> with the project ID that you have chosen on Firebase.

This file should then be committed to version control. You can also create a .firebaserc file if you don't want to manually pass your project ID to your firebase commands (with `--project <your_project_id>):

{
  "projects": {
    "default": "<your_project_id>"
  }
}

Then, just add Firebase dependencies to your project:

yarn add --dev firebase-admin firebase-functions firebase-functions-test

Using Firebase CLI

You may instead prefer to set up your project with the firebase CLI, which will fetch your project ID for you, add required dependencies (see above) and even set up automated deployments via GitHub Actions.

# Install firebase CLI globally
yarn global install firebase-tools
# Initialize your firebase project
firebase login
firebase init hosting

When prompted, you can enter .output/public as the public directory. Don't select that this will be a single-page app.

Once complete, add the following to your firebase.json to enable server rendering in Cloud Functions:

{
  "functions": { "source": ".output/server" },
  "hosting": [
    {
      "site": "<your_project_id>",
      "public": ".output/public",
      "cleanUrls": true,
      "rewrites": [{ "source": "**", "function": "server" }]
    }
  ]
}

You can find more details in the Firebase documentation.

Local preview

You can preview a local version of your site if you need to test things out without deploying.

NITRO_PRESET=firebase yarn build
firebase emulators:start

Deploy to Firebase Hosting via CLI

Deploying to Firebase Hosting is a simple matter of just running the firebase deploy command.

NITRO_PRESET=firebase yarn build
firebase deploy
