Eleventy

This guide shows you how to deploy a Eleventy application on Layer0.

Example

System Requirements

Sign up for Layer0

Deploying requires an account on Layer0. Sign up here for free.

Install the Layer0 CLI

If you have not already done so, install the Layer0 CLI

Terminal
npm i -g @layer0/cli

Create a new Eleventy app

If you don’t already have a Eleventy app, create one by running the following:

Terminal
npm install -g @11ty/eleventy

mkdir project-name
cd project-name

echo '# Page header' > README.md

You can verify your app works by running it locally with:

Terminal
eleventy --serve

Configuring your Eleventy app for Layer0

Create a package.json at the root of your project with the following:

JavaScript
{
  "name": "eleventy",
  "version": "1.0.0",
  "scripts": {
    "build": "eleventy",
    "deploy": "layer0 deploy"
  },
  "dependencies": {},
  "devDependencies": {}
}

Initialize your project

In the root directory of your project run 0 init:

Terminal
0 init

This will automatically update your package.json and add all of the required Layer0 dependencies and files to your project. These include:

  • The @layer0/core package - Allows you to declare routes and deploy your application on Layer0
  • The @layer0/prefetch package - Allows you to configure a service worker to prefetch and cache pages to improve browsing speed
  • layer0.config.js - A configuration file for Layer0
  • routes.js - A default routes file that sends all requests to Eleventy.

Configure the routes

Update routes.js at the root of your project to the following:

JavaScript
// This file was added by layer0 init.
// You should commit this file to source control.

import {Router} from '@layer0/core/router';

export default new Router().static('_site', ({cache}) => {
  cache({
    edge: {
      maxAgeSeconds: 60 * 60 * 60 * 365,
      forcePrivateCaching: true,
    },
    browser: {
      maxAgeSeconds: 0,
      serviceWorkerSeconds: 60 * 60 * 24,
    },
  });
});

Refer to the Routing guide for the full syntax of the routes.js file and how to configure it for your use case.

Run the Eleventy app locally on Layer0

Create a production build of your app by running the following in your project’s root directory:

Terminal
npm run build

Run Layer0 on your local machine:

Terminal
0 dev

Load the site http://127.0.0.1:3000

Deploying

Create a production build of your app by running the following in your project’s root directory:

Terminal
npm run build

Next, deploy the build to Layer0 by running the 0 deploy command:

Terminal
0 deploy

Refer to the Deploying guide for more information on the deploy command and its options.
