The command saber build creates a public directory with a production build of your app. Set up your favorite HTTP server to properly serve static .html files and other static assets.

Built-in Static Server

You can use the built-in static server via the saber serve command, it automatically serves the public directory:

cd my-site
yarn saber build
yarn saber serve

This is great for previewing the production build locally.

Other Solutions

You don't need the built-in static server in order to serve a Saber application, it works just fine with most static servers, for example you can use sirv-cli:

npx sirv-cli public

Or serve:

npx serve public

Building for Relative Paths

By default, Saber produces a build assuming your app is hosted at the server root. To override this, specify the build.publicUrl in your Saber config file, for example:

// saber.config.js
module.exports = {
  build: {
    publicUrl: '/blog/'


To setup continuous delivery:

With this setup Netlify will build and deploy when you push to git or open a pull request:

  1. Start a new netlify project
  2. Pick your Git hosting service and select your repository
  3. Click Build your site

Since Netlify automatically rewrites routes like /foo to /foo.html when /foo doesn't exist, you may need saber-plugin-netlify-redirect to fix this.

GitHub Pages

Step 1: Install gh-pages and add deploy to scripts in package.json

npm i -D gh-pages

Alternatively you may use yarn:

yarn add gh-pages --dev

Add the following scripts in your package.json:

  "scripts": {
+   "predeploy": "npm run build",
+   "deploy": "gh-pages -d public -t",
    "dev": "saber",
    "build": "saber build",

Step 2: Add .nojekyll to turn off Jekyll

Adding a file .nojekyll (with empty content) to the static/ folder to turn off Jekyll integration of GitHub Pages.

Step 3: Optionally, configure the domain or repository path

If you are using a custom domain, you can configure it with GitHub Pages by adding a CNAME file to the static/ folder.

Your CNAME file should look like this:

If you are using a repository-level gh-pages deployment ([username][repository name]), set the publicUrl property in the Saber configuration file. This is not required for account-level gh-pages deployments ([username]

Step 4: Deploy the site by running npm run deploy

Then run:

npm run deploy

Step 5: For a project page, ensure your project’s settings use gh-pages

Finally, make sure GitHub Pages option in your GitHub project settings is set to use the gh-pages branch:



Vercel is a cloud platform that enables developers to host Jamstack websites and web services that deploy instantly, scale automatically, and requires no supervision, all with zero configuration. They provide a global edge network, SSL encryption, asset compression, cache invalidation, and more.

Step 1: Deploying your Saber Website to Vercel

To deploy your Saber app with a Vercel for Git Integration, make sure it has been pushed to a Git repository.

Import the project into Vercel using the Import Flow. During the import, you will find all relevant options preconfigured for you; however, you can choose to change any of these options, a list of which can be found here.

After your project has been imported, all subsequent pushes to branches will generate Preview Deployments, and all changes made to the Production Branch (commonly "main") will result in a Production Deployment.

Once deployed, you will get a URL to see your app live, such as the following:


To host and deploy your site to Firebase.

Step 1: Create a new web app and select "Also setup Firebase Hosting for this app"

Step 2: Add the required Firebase scripts to the body of your site

// saber.browser.js
export default ({
}) => {
      script: [{
        src: '/__/firebase/6.6.1/firebase-app.js',
        body: true
        src: '/__/firebase/init.js',
        body: true

Step 3: Install the Firebase CLI, login and create a firebase config in the root of your project.

npm install -g firebase-tools # Install the CLI
firebase login # This will open a new browser window follow the instructions
firebase init # Follow the instructions, choose the hosting option

Step 4: Add the following script in your package.json:

  "scripts": {
    "dev": "saber",
    "build": "saber build",
+   "deploy": "npm run build && firebase deploy"

Deploy your site

npm run deploy

Step 5: To configure firebase to strip trailing slash (Optional)

Add "trailingSlash: false to your firebase.json config.

// firebase.json example
  "hosting": {
    "public": "public",
    "cleanUrls": true,
    "trailingSlash": false,
    "ignore": [
