Description:

Configuration Structure

1. ibexa.webpack.all.configs.js – The main file that aggregates all configuration files.
2. ibexa.webpack.ibexa.configs.js – Configuration for Ibexa core components (previously in ./ibexa.webpack.config.js).
3. ibexa.webpack.libs.configs.js – Configuration for libraries. This file currently includes two configurations:
   1. React – previously defined in admin-ui/src/bundle/Resources/encore/ibexa.webpack.custom.config.js
   2. ReactDOM – previously defined in admin-ui/src/bundle/Resources/encore/ibexa.webpack.custom.config.js
4. ibexa.webpack.richtext.configs.js – Configuration for the Rich Text editor, previously defined in fieldtype-richtext/src/bundle/Resources/encore/ibexa.webpack.custom.config.js.
5. ibexa.webpack.internals.configs.js – Configuration for internal modules, replacing the former <bundle>/src/bundle/Resources/encore/ibexa.webpack.custom.config.js files for internal use.

Custom configuration files located at <bundle>/src/bundle/Resources/encore/ibexa.webpack.custom.config.js are intended for client-side customization and are loaded in the main ./webpack.config.js.
For internal purposes, these have been replaced by <bundle>/src/bundle/Resources/encore/ibexa.webpack.internals.config.js.

Summary:

• Files named <bundle>/src/bundle/Resources/encore/ibexa.webpack.custom.config.js are intended for client customization and are loaded via webpack.config.js.
• For internal custom configurations, use <bundle>/src/bundle/Resources/encore/ibexa.webpack.internals.config.js.
