Prerequisites

Setup requires:

Install the Edgio CLI

If you have not already done so, install the Edgio CLI.
Bash
1npm i -g @edgio/cli@^6.0.0

Create a new Preact app

If you don’t already have a Preact app, create one by running the following:
Bash
1npx preact-cli create default my-project
2cd my-project
You can verify your app works by running it locally with:
Bash
1npm run dev

Configuring your Preact app for Edgio

Initialize your project

In the root directory of your project run edgio init:
Bash
1edgio init --edgioVersion ^6.0.0
This will automatically update your package.json and add all of the required Edgio dependencies and files to your project. These include:
  • The @edgio/core package - Allows you to declare routes and deploy your application on Edgio
  • The @edgio/prefetch package - Allows you to configure a service worker to prefetch and cache pages to improve browsing speed
  • edgio.config.js - A configuration file for Edgio
  • routes.js - A default routes file that sends all requests to Preact.

Configure the routes

Update routes.js at the root of your project to the following:
JavaScript
1// This file was added by edgio init.
2// You should commit this file to source control.
3

4import { Router } from '@edgio/core/router'
5

6export default new Router()
7  // Create serveStatic route for each file in the folder build with a cache-control header of 's-maxage=315360000'
8  .static('build')
9  .fallback(({ appShell }) => {
10    appShell('build/index.html')
11  })
Refer to the CDN-as-code guide for the full syntax of the routes.js file and how to configure it for your use case.

Run the Preact app locally on Edgio

Create a production build of your app by running the following in your project’s root directory:
Bash
1npm run build
Test your app with the Sites on your local machine by running the following command in your project’s root directory:
Bash
1edgio 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:
Bash
1npm run build
Deploy your app to the Sites by running the following command in your project’s root directory:
Bash
1edgio deploy
Refer to the Deployments guide for more information on the deploy command and its options.
