@WebStormIDE Have you thought about releasing 2 versions of webstorm (both paid), 1 would be the current one and the other a kind of PRO version that would include database plugins. NodeJS has support for databases you know :-)
If you have All Products Pack, then you can simply install this plugin: http://plugins.jetbrains.com/plugin/10925-database-tools-and-sql …. It will let you use all the DataGrip features inside WebStorm. We hope this helps
