Deploy a Hydrogen app

You're using the most recent version of Hydrogen. The latest release gives you the benefits of performance enhancements, new components, and other best practices.

Oxygen is Shopify's recommended deployment platform for Hydrogen apps.

You can deploy your Hydrogen app to Node.js, an open-source JavaScript runtime environment.

1. Check the port ($PORT) that's specified in the server.js file.

2. Run your Hydrogen app on the port specified by executing the following commands:

   If you're using the default port, then the production version of your app will be running at http://localhost:8080.

If you're using the default server entry point in the build:server script (@shopify/hydrogen/platforms/node), then the generated server bundle (dist/server/index.js) consists of a simple Node.js server that uses Connect middleware.

This bundle also exports the createServer function, which you can call programmatically to apply extra middleware:

If you want to use a different Node.js framework like Express or Fastify, then complete the following steps:

1. Create a new server entry point (for example, server.js) and import hydrogenMiddleware:

2. Update the scripts in package.json to specify your new entry point. If the scripts are located in <root>/server.js, then the changes would look like the following:

3. Run the server bundle:

If your server isn't compatible with Connect middleware or you're deploying to a serverless platform, then you can directly use the App.server.jsx file as the server entry point.

Update the scripts in package.json to specify your new entry point:

This exposes a handleRequest function that can be imported in your server or serverless function:

You can deploy your project to any platform that supports Docker-based hosting, like Google Cloud Run, Fly.io, and Heroku. If you've generated a Node.js server, then you can run it inside a Docker container.

1. Install Docker.

2. Add a Docker file to the root of your project:

3. Run Docker inside your app directory by executing the following commands:

   The production version of your app will be running at http://localhost:8080.

You can deploy your Hydrogen app to Cloudflare Workers, a serverless application platform. For the Cloudflare Workers' Cache API to work, you need to meet the following requirements:

• You have a Cloudflare domain. The domain can't be worker.dev, because Cloudflare owns this domain.
• You have a DNS record for the Cloudflare domain. For example, A example.dev 192.0.2.1 Proxied.
• You have a worker route that points to the Cloudflare domain.

1. Create a Hydrogen app locally.

2. Create a wrangler.toml file in the root of your project.

   For more information about the configurable properties in the wrangler.toml file, refer to Cloudflare's configuration and compatibility dates documentation.

   Your static files are now uploaded to Workers KV.

3. Install Cloudflare's KV asset handler:

4. Create a new Worker entry file (for example, worker.js) in your project:

5. Update package.json to specify the new Worker entry point. If the entry point is in <root>/worker.js, then the changes look like the following:

6. Deploy your project with Wrangler:
