Firebase Hosting gives you a fast, secure, and reliable way to host your app's static assets (HTML, CSS, JavaScript, media files, etc.) as well as to serve dynamic content and host microservices.
Our production-grade hosting is backed by a global content delivery network
(CDN). Hosting serves your content over SSL, by default, and can be used
with your own custom domain or on your project's
subdomains at no cost on web.app and firebaseapp.com.
Before you can set up Firebase Hosting, you need to create a Firebase project.
Visit the Firebase CLI documentation to learn how to install the CLI or update to its latest version.
To connect your local project files to your Firebase project, run the following command from the root of your local project directory:
firebase init hosting
During project initialization, from the Firebase CLI prompts:
Select a Firebase project to connect to your local project directory.
The selected Firebase project is your "default" Firebase project for your local project directory. To connect additional Firebase projects to your local project directory, set up project aliases.
Specify a directory to use as your public root directory.
This directory contains all your publicly served static files, including your
index.html file and any other assets that you want to deploy to
Firebase Hosting.
Static apps: If you are deploying a static app:
The default for the public root directory is called public.
You can specify your public root directory now or you can
specify it later in your
firebase.json configuration file.
If you select the default and don't already have a directory called
public, Firebase creates it for you.
If you don't already have a valid index.html file or 404.html file in
your public root directory, Firebase creates them for you.
Opt into App Hosting: If the CLI detects features of an SSR web framework like Next.js or Angular Universal, it may recommend initializing Firebase App Hosting instead. App Hosting is the recommended deployment solution for full-stack framework apps. You can proceed with App Hosting setup or continue with Hosting (classic) for static-only deploys.
Choose a configuration for your site.
If you select to make a one-page app, then Firebase automatically adds rewrite configurations for you.
At the end of initialization, Firebase automatically creates and adds two files to the root of your local app directory:
A firebase.json configuration file that lists your project configuration.
Learn more about this file on the
configure hosting behavior page.
A .firebaserc file that stores your
project aliases.
To deploy to your site, run the following command from the root of your local project directory:
firebase deploy --only hosting
This command deploys your Hosting content and config to the following Firebase-provisioned subdomains:
PROJECT_ID.web.appPROJECT_ID.firebaseapp.comLearn more about deploys and even locally testing your site.
Now your site is ready to share with the world!
Continue to improve your site. Test locally, share changes at a temporary preview URL, then deploy to your live site. Follow this step-by-step guide.
