LiveReload Setup#

LiveReload routing is currently supported on the magento2, pwa-studio and shopware environment types. Other environment types may utilize LiveReload via per-project compose configurations to set up the routing for LiveReload JS and WebSocket endpoints.

Configuration for Magento 2#

Magento 2 bundles an example grunt based server-side compilation workflow which includes LiveReload, and it works within the Reward shell environment. In order to use this:

  1. Rename or copy Gruntfile.js.sample file to Gruntfile.js in your project root.

  2. Rename or copy package.json.sample file to package.json in your project root.

  3. Run npm install to install the required NodeJS packages as defined in package.json.

  4. Merge the following into your project’s app/etc/env.php configuration file:

return [
    'system' => [
        'default' => [
            'design' => [
                'footer' => [
                    'absolute_footer' => '<script defer src="/livereload.js?port=443"></script>'


You can achieve this by running the following command:

$ reward shell bin/magento config:set --lock-env \
    'design/footer/absolute_footer' '<script defer src="/livereload.js?port=443"></script>'


This can be accomplished via alternative means, the important part is the browser requesting /livereload.js?port=443 when running the site on your local development environment.

  1. Run bin/magento app:config:import to load merged configuration into the application.

With the above configuration in place, you’ll first enter the FPM container via reward shell and then setup as follows:

  1. Clean and build the project theme using grunt:

$ grunt clean
$ grunt exec:blank
$ grunt less:blank
  1. Thereafter, only a single command should be needed for daily development:

$ grunt watch


Grunt should be used within the php-fpm container entered via reward shell

This setup will also be used to persist changes to your compiled CSS. When you run grunt watch, a LiveReload server will be started on ports 35729 within the php-fpm container and Traefik will take care of proxying the JavaScript tag and WebSocket requests to this listener.

On a working setup with grunt watch running within reward shell you should see something like the following in the network inspector after reloading the project in a web browser.

LiveReload Network Requests

Configuration for Shopware#

Shopware Hot Reload functionality requires an additional port on the same hostname.

To configure the additional port, you will have to configure Traefik.

Open Reward Global Configuration (default: ~/.reward.yml) and add the following line:

reward_traefik_bind_additional_https_ports: [ 9998 ]

When it’s done, restart Traefik.

reward svc down
reward svc up

If you open Traefik dashboard, you should see the new port in the entrypoints section.

Traefik Additional HTTPS Port

When it’s done you have to configure this additional port on the PHP container as well. Add the following line to the project’s .env file:


And restart the environment.

reward env down
reward env up

Now if you start the Live Reload server, the requests will be proxied to it.

reward shell
./psh.phar storefront:hot-proxy
