Autocomplete in webstorm express?

Question

Node.js

Many expresss routing methods like put(),delete(),post() etc output: unresolved function even though it works just fine when compiled, it means there is a problem with the webshtorm.
I tried to download express from github but nothing changed.
I'm using the EAP version.
How to fix it?

Answer 1

Settings -> Languages ​​& Framework -> Javascript -> Libraries -> Download
There you find express (and much more that you need)
And enable Node.js and NPM
