Why my node_modules folder is excluded in my phpStorm? - node.js

Question

[Hello guys! every time i run the npm installcommand, it creates the node_modules folder, but the folder is excluded! Also i have some warnings as you can see, but i think that npm install is done successfully.
the Warnings that i get are the following:
npm WARN deprecated minimatch#2.0.10: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue
npm WARN deprecated minimatch#0.2.14: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue
npm WARN deprecated graceful-fs#1.2.3: graceful-fs v3.0.0 and before will fail on node releases >= v7.0. Please update to graceful-fs#^4.0.0 as soon as possible. Use 'npm ls graceful-fs' to find it in the tree.
npm WARN prefer global marked#0.3.6 should be installed with -g
npm WARN prefer global node-gyp#3.4.0 should be installed with -g
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents#^1.0.0 (node_modules\chokidar\node_modules\fsevents):
npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents#1.0.15: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})
The first 3 warnings are from the gulp depentency. and the last 2 i can pass them by, if i type the following code in the package.json:
*"optionalDependencies": {
"fsevents": "*"
},*
and then type into the terminal the command npm install --no-optional.
But i can't understand why my node_modules folder is excluded and PhpStorm(2016.2.2) doesn't allow me to unexcluded it.
Thank you!]1

I believe they're not considered source files, as the contents of the node_modules folder are imported dependencies.
Having that folder excluded helps to to speed up searching in your project; as PhpStorm doesn't need to search through all the external modules.
This is what the JetBrains documentation has to say:
Excluded folders are not involved in indexing and therefore they are ignored while searching, parsing, watching etc.,
So there's nothing wrong with having a folder marked as 'excluded'.
However, should you want to un-exclude the node_modules folder, have a look at this thread on JetBrains support. This thread was started by someone with the same problem. One of the suggestions there:
Please open "Settings | Languages & Frameworks | JavaScript | Libraries" and locate "/lib/node_modules" library. Is it enabled? If no, just enable it. Will it bring expected code completion and navigation in your main application for modules imported from lib/node_modules?
