I'm working on a project that uses Firebase Cloud Firestore as its data back-end.
The work on the Security Rules file has now come to a stage where I simply cannot edit it in WebStorm, due to lack of syntax highlight.
There is an issue about this, since 2 years back - only 27 votes.
I'm trying to find other IntelliJ customers hurt by this, or alternatively someone used to making syntax highlighting plugins for IntelliJ IDEs.
My work-arounds are either to use the Firebase online editor, and copy-paste the changes back-forth to the local file (sucks), or the Visual Code IDE which has highlighting but I'm otherwise unaccustomed to work with.
