This guide shows you how to deploy an Gatsby application on the Moovweb XDN:

Install Node.js and npm

XDN only supports Node.js version 12 and higher

If you do not have Node.js installed on your system, download and install it from the official Node.js v12.x downloads page. Select the download that matches your operating system and run the installer. Note that the installer for Node.js will also install npm.

Note that while you can use any version of Node.js >= 12 locally, your app will run in Node 12 when deployed to the XDN cloud. Therefore we highly suggest using Node 12 for all development.

Getting Started

If you don't already have a Gatsby application, you can create one using:

npm install -g gatsby-cli
gatsby new gatsby-site

You should now have a working Gatsby site. Run gatsby develop to see the application running on localhost:8000.

To deploy your Gatsby on Moovweb XDN:

  1. Install the XDN CLI globally:
npm install -g @xdn/cli
  1. Run the following in the root folder of your project. This will configure your project for the XDN.
xdn init

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

  • The @xdn/core package
  • The @xdn/gatsby package
  • The @xdn/cli package
  • xdn.config.js
  • routes.js - A default routes file that sends all requests to your Gatsby static site. Update this file to add caching or proxy some URLs to a different origin.

Running Locally

You can test the integration of the XDN router with your gatsby site locally using:

xdn run


Deploying requires an account on the Moovweb XDN. Sign up here for free. Once you have an account, you can deploy to the Moovweb XDN by running the following in the root folder of your project:

xdn deploy

See Deploying guide for more information.


The default routes.js file created by xdn init sends all requests to the Gatsby static site.

// This file was automatically added by xdn deploy.
// You should commit this file to source control.

const { Router } = require('@xdn/core/router')
const { gatsbyRoutes } = require('@xdn/gatsby')

module.exports = new Router().use(gatsbyRoutes)

Adding routes to a different origin

To proxy some URLs to a different origin, you need first to configure that origin in your xdn.config.js file.

For example:

// xdn.config.js

module.exports = {
  backends: {
    legacy: {
      domainOrIp: process.env.LEGACY_BACKEND_DOMAIN || '',
      hostHeader: process.env.LEGACY_BACKEND_HOST_HEADER || '',

Using environment variables here allows you to configure different legacy domains for each XDN environment.

Then you can add routing and caching rules to your routes.js file. Note that gatsbyRoute must be declared last as it acts as a fallback route.

For example:

// routes.js

const { Router } = require('@xdn/core/router')
const { gatsbyRoutes } = require('@xdn/gatsby')

module.exports = new Router()
  .get('/some/legacy/url/:p', ({ proxy }) => {
