node_modules slows down PhpStorm IDE terribly

Hello,

Despite the fact that node_module folder is excluded automatically in project, it terrible slows down the development. Each time I type "this." statement the IDE freezes for about 2-3 second! Once I removed this folder form project it works fine... or when I simply switch highlighting level to none but in that case PhpStrom is just like any other text editor.

I tried PhpStorm before for developing simple JS programs and it was fine... seems like it is trying to go deep in node_modules folder and searching for appropriate hint every time when I am typing the code. Is there any way to fix that?

Thanks in advance
