"""Custom rollup_bundle for language service.
|
||
|
|
|
||
|
|
Overrides format to AMD and produces only umd and min, no FESM.
|
||
|
|
|
||
|
|
We do this so that we bundle all of the dependencies into the bundle
|
||
|
|
except for typescript, fs and path.
|
||
|
|
|
||
|
|
This allows editors and other tools to easily use the language service bundle
|
||
|
|
without having to provide all of the angular specific peer dependencies.
