Firebase CLI Build Status Coverage Status NPM version

These are the Firebase Command Line Interface (CLI) Tools. They can be used to:

  • Deploy code and assets to your Firebase projects
  • Run a local web server for your Firebase Hosting site
  • Interact with data in your Firebase database
  • Import/Export users into/from Firebase Auth

To get started with the Firebase CLI, read the full list of commands below or check out the hosting-specific CLI documentation.

Installation

To install the Firebase CLI, you first need to sign up for a Firebase account.

Then you need to install Node.js and npm. Note that installing Node.js should install npm as well.

Once npm is installed, get the Firebase CLI by running the following command:

npm install -g firebase-tools

This will provide you with the globally accessible firebase command.

Commands

The command firebase --help lists the available commands and firebase <command> --help shows more details for an individual command.

If a command is project-specific, you must either be inside a project directory with an active project alias or specify the Firebase project id with the -P <project_id> flag.

Below is a brief list of the available commands and their function:

Administrative Commands

Command Description
login Authenticate to your Firebase account. Requires access to a web browser.
logout Sign out of the Firebase CLI.
login:ci Generate an authentication token for use in non-interactive environments.
list Print a list of all of your Firebase projects.
setup:web Print out SDK setup information for the Firebase JS SDK.
use Set active Firebase project, manage project aliases.
open Quickly open a browser to relevant project resources.
init Setup a new Firebase project in the current directory. This command will create a firebase.json configuration file in your current directory.
help Display help information about the CLI or specific commands.

Append --no-localhost to login (i.e., firebase login --no-localhost) to copy and paste code instead of starting a local server for authentication. A use case might be if you SSH into an instance somewhere and you need to authenticate to Firebase on that machine.

Deployment and Local Development

These commands let you deploy and interact with your Firebase Hosting site.

Command Description
deploy Deploys your Firebase project. Relies on firebase.json configuration and your local project folder.
serve Start a local web server with your Firebase Hosting configuration. Relies on firebase.json.

Auth Commands

Command Description
auth:import Batch importing accounts into Firebase from data file.
auth:export Batch exporting accounts from Firebase into data file.

Detailed doc is here.

Database Commands

Command Description
database:get Fetch data from the current project's database and display it as JSON. Supports querying on indexed data.
database:set Replace all data at a specified location in the current project's database. Takes input from file, STDIN, or command-line argument.
database:push Push new data to a list at a specified location in the current project's database. Takes input from file, STDIN, or command-line argument.
database:remove Delete all data at a specified location in the current project's database.
database:update Perform a partial update at a specified location in the current project's database. Takes input from file, STDIN, or command-line argument.
database:profile Profile database usage and generate a report.

Cloud Functions Commands

Command Description
functions:log Read logs from deployed Cloud Functions.
functions:config:set Store runtime configuration values for the current project's Cloud Functions.
functions:config:get Retrieve existing configuration values for the current project's Cloud Functions.
functions:config:unset Remove values from the current project's runtime configuration.
functions:config:clone Copy runtime configuration from one project environment to another.

Hosting Commands

Command Description
hosting:disable Stop serving Firebase Hosting traffic for the active project. A "Site Not Found" message will be displayed at your project's Hosting URL after running this command.

Using with CI Systems

The Firebase CLI requires a browser to complete authentication, but is fully compatible with CI and other headless environments.

  1. On a machine with a browser, install the Firebase CLI.
  2. Run firebase login:ci to log in and print out a new access token (the current CLI session will not be affected).
  3. Store the output token in a secure but accessible way in your CI system.

There are two ways to use this token when running Firebase commands:

  1. Store the token as the environment variable FIREBASE_TOKEN and it will automatically be utilized.
  2. Run all commands with the --token <token> flag in your CI system.

The order of precedence for token loading is flag, environment variable, active project.

On any machine with the Firebase CLI, running firebase logout --token <token> will immediately revoke access for the specified token.

Using as a Module

The Firebase CLI can also be used programmatically as a standard Node module. Each command is exposed as a function that takes an options object and returns a Promise. For example:

var client = require('firebase-tools');
client.list().then(function(data) {
  console.log(data);
}).catch(function(err) {
  // handle error
});

client.deploy({
  project: 'myfirebase',
  token: process.env.FIREBASE_TOKEN,
  cwd: '/path/to/project/folder'
}).then(function() {
  console.log('Rules have been deployed!')
}).catch(function(err) {
  // handle error
});
