React Static

This guide shows you how to deploy a React Static application on 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

npm i -g @layer0/cli # yarn global add @layer0/cli

Create a new React Static app

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

npm i -g react-static
react-static create
cd project-name # The root directory of your project

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

yarn start

Configuring your React Static app for Layer0

Initialize your project

In the root directory of your project run 0 init:

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 React Static.

Configure the routes

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

// 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('dist', ({ 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 React Static app locally on Layer0

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

npm run build

Run Layer0 on your local machine:

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:

npm run build

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

0 deploy

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