Our Ember build compiles assets into multiple chunks. In the past, we used the output from ember-auto-import-chunks-json-generator to give Rails a map of those chunks. However, that addon is specific to ember-auto-import, and is not compatible with Embroider. Instead, we can switch to parsing the html files which are output by ember-cli. These are guaranteed to have the correct JS files in the correct place. A <discourse-chunked-script> will allow us to easily identify which chunks belong to which entrypoint. In future, as we update more entrypoints to be compiled by Embroider/Webpack, we can easily introduce new wrappers. Previously applied in 2c58d45 and reverted in 24d46fd. This version has been updated for subfolder support.
