 Not every plugin can be used here. `output.plugins` is limited to plugins that only use hooks that run during `bundle.generate()` or `bundle.write()`, i.e. after Rollup's main analysis is complete. If you are a plugin author, see [output generation hooks](guide/en/#output-generation-hooks) to find out which hooks can be used.
