Magento_Baler module introduces functionality to preload theme JS bundles configuration (core-bundle.js & requirejs-bundle-config.js) generated by Baler - tool for static analysis of Javascript dependencies.
This functionality is disabled by default and it can be enabled on the configuration page (Stores -> Configuration -> Advanced -> Developer -> Javascript Settings).
Developer settings is not displayed in production mode. To enable this feature in production mode, the CLI command bin/magento config:set dev/js/enable_baler_js_bundling 1 can be used.

1. The following features should be disabled when Magento_Baler is enabled:
   • JS Bundling
   • JS Minification

mkdir app/code/Magento
git clone https://github.com/magento/m2-baler.git app/code/Magento/Baler
bin/magento setup:upgrade

Open you composer.json and change "minimum-stability": "stable" to "minimum-stability": "dev" and add "prefer-stable": true.

This means that composer will always use stable package unless there is one. If there is no stable package it will use dev version, then run:

composer config repositories.magento-baler vcs [email protected]:magento/m2-baler.git
composer require magento/module-baler:dev-master
bin/magento module:enable Magento_Baler
bin/magento setup:upgrade
