{@a payload-size-debugging}
### Payload size debugging
If you notice that the size of your application's main bundle has increased with Ivy, you may want to check the following:
1. Verify that the components and `NgModules` that you want to be lazy loaded are only imported in lazy modules.
Anything that you import outside lazy modules can end up in the main bundle.
See more details in the original issue [here](https://github.com/angular/angular-cli/issues/16146#issuecomment-557559287).
1. Check that imported libraries have been marked side-effect-free.
If your app imports from shared libraries that are meant to be free from side effects, add "sideEffects": false to their `package.json`.
This will ensure that the libraries will be properly tree-shaken if they are imported but not directly referenced.
See more details in the original issue [here](https://github.com/angular/angular-cli/issues/16799#issuecomment-580912090).
