template-registry warning Generated an empty chunk while rollup

[mkszepp]

I have seen that there will exported template-registry as empty file:

Last test run:
https://github.com/adopted-ember-addons/ember-file-upload/actions/runs/7606502732/job/20712414961#step:4:40

Edit: found this issue on addon blueprint embroider-build/addon-blueprint#195 (comment)

Edit 2: While working on a other addon i have found out, that line is not necessary and generates the empty file. we can remove it:
https://github.com/adopted-ember-addons/ember-file-upload/blob/master/ember-file-upload/rollup.config.mjs#L27

Ah nice find. I think you're right.

I was under the impression that only publicEntrypoints entries could be imported by a consuming app. But it doesn't seem to affect the build output except for removing that empty file.

This isn't actually covered by the test suite though – since the template registry is only used by Glint's "loose mode" and the test-app is now in "strict mode". I don't really want to add a whole test app just to cover that 🤔

Do you have an Ember app running Glint in "loose" mode that you can test this with?

Would prefer we check it now than find out through a bug report 😅

Unfortunately I don't have an app that has loose mode active... i have discoverd this only while other addon migration.
In ember-page-title they do not export it in publicEntrypoint (the file is only present in declaration folder)...

I have seen that the addon-blueprint brings this line... so maybe this is a bug from blueprint.. i have for now created a issue in addon-blueprint (embroider-build/addon-blueprint#252)... maybe we wait for feedback and than we go on
