A rollup plugin that makes sure you don't accidentally import something statically, which could have an effect on your bundle size.
Tag files you want to be in the same group by adding a comment with the group name.
// rollup-plugin-bundle-guard: group=entry
If you attempt to statically import a file that is not in the same group, your build will fail with something like:
"entry.js" statically imports "load-me-dynamically.js" which is not allowed. Should it be in "entry"?
With strict mode disabled anything that is not assigned a group will default to the group named
default, and anything is allowed to import something assigned to the
Each module can only be assigned to a single group. You can however include additional groups that are allowed to import the module with the following comment:
// rollup-plugin-bundle-guard: allowedImportFrom=<group 1 name> <group 2 name> ...
This makes it possible for separate bundles to statically import shared dependencies.
