What is firebase-tools?
The firebase-tools npm package provides a command-line interface (CLI) for managing Firebase projects and their resources. It allows developers to deploy, configure, and manage Firebase services such as Firestore, Realtime Database, Authentication, Hosting, Cloud Functions, and more.
What are firebase-tools's main functionalities?
Deploying Firebase Hosting
This command deploys your web app to Firebase Hosting. It uploads your local files to Firebase and makes them available on your Firebase project's web URL.
firebase deploy --only hosting
Deploying Cloud Functions
This command deploys your Cloud Functions to Firebase. It uploads your function code to Firebase and makes it available to be triggered by events.
firebase deploy --only functions
Deploying Firestore Rules
This command deploys your Firestore security rules. It uploads your rules to Firebase, ensuring that your Firestore database is protected according to your specifications.
firebase deploy --only firestore:rules
Emulating Firebase Services
This command starts the Firebase emulators for local development. It allows you to test your Firebase app locally without interacting with the live Firebase services.
firebase emulators:start
Initializing a Firebase Project
This command initializes a new Firebase project in your local directory. It sets up the necessary configuration files and allows you to select which Firebase services you want to use.
firebase init
Other packages similar to firebase-tools
aws-cli
The AWS CLI is a unified tool to manage your AWS services. It provides similar functionalities to firebase-tools but for AWS services. It allows you to control multiple AWS services from the command line and automate them through scripts.
gcloud
The gcloud CLI is a command-line tool for interacting with Google Cloud Platform services. It offers functionalities similar to firebase-tools but for a broader range of Google Cloud services. It allows you to deploy, manage, and configure Google Cloud resources.
netlify-cli
The Netlify CLI provides a command-line interface for interacting with Netlify services. It offers functionalities similar to Firebase Hosting, allowing you to deploy and manage web projects on the Netlify platform.
firebase-tools
These are the Firebase Command Line (CLI) Tools. They can be used to:
- Administer your Firebase account
- Run a local web server for your Firebase Hosting site
- Interact with data in your Firebase database
- Deploy your site to Firebase Hosting
- Deploy Security Rules for your database
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 a
firebase.json
configuration file or specify the Firebase project name with the -f <project>
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. |
list | Print a list of all of your Firebase projects. |
open | Open the deployed Firebase Hosting site or various dashboard panels for the current Firebase project. |
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. |
prefs:token | Print out your authenticated access token for use in CI/headless systems. |
Deploy and Hosting Commands
These commands let you deploy and interact with your Firebase Hosting site.
Command | Description |
---|
deploy | Deploys all components (both hosting and security rules) of your Firebase project. Relies on firebase.json configuration. |
deploy:hosting | Deploy only the Firebase Hosting site assets to your Firebase project. Relies on firebase.json configuration. |
deploy:rules | Deploy only the Firebase Security Rules to your Firebase project. Relies on firebase.json configuration. |
disable:hosting | Stop serving Firebase Hosting traffic for the current project. A "Site Not Found" message will be displayed at your URL after running this command. |
serve | Start a local web server with your Firebase Hosting configuration. Relies on firebase.json. |
Data Commands
Command | Description |
---|
data:get | Fetch data from the current project's database and display it as JSON. Supports querying on indexed data. |
data:set | Replace all data at a specified location in the current project's database. Takes input from file, STDIN, or command-line argument. |
data:update | Perform a partial update at a specified location in the current project's database. Takes input from file, STDIN, or command-line argument. |
data: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. |
data:remove | Delete all data at a specified location in the current project's database. |
Using with CI Systems
The Firebase CLI requires a browser to complete authentication, but is fully
compatible with CI and other headless environments.
- On a machine with a browser, install the Firebase CLI and login.
- Run
firebase prefs:token
to print out the access token once you've logged in. - Store the output token in a secure but accessible way in your CI system.
- Run all commands with the
--token <token>
parameter in your CI system. For
example, if I had my token stored as the environment variable FIREBASE_TOKEN
I could run firebase deploy --token $FIREBASE_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) {
});
client.deploy.rules({
firebase: 'myfirebase',
token: process.env.FIREBASE_TOKEN,
cwd: '/path/to/project/folder'
}).then(function() {
console.log('Rules have been deployed!')
}).catch(function(err) {
});
