[Feature Request]Make `emitFile` tree shakingable

[alexander-akait]

For example my plugin can create robots.txt file based on assets

[alexander-akait]

Yes, expected, because other plugins can use this assets for any purpose, we can't remove it, anyway you don't have code for this import in your bundle

@evilebottnawi Thanks for your reply.

But as I said, "This will waste space of the server if we upload it when we publish every time" which is a problem

Is there any way to know whether the file be used? If so, I can write a custom emitFile

Just avoid unnecessary imports

No

I think this is not very easy just like we need tree-shaking rather than avoid unnecessary imports

No

But from "because other plugins can use this assets for any purpose, we can't remove it", seems(myabe I misunderstand) there is a way to know "whether the file be used", just because "other plugins can use this assets for any purpose", so you still "can't remove it" even you know the file not be used?

No ways, so we can't remove it

But you can write own plugin for this, but it will be not easy
