Hi,
I could install directly on the XSA Client the missing npm squel package.
Do I've to do something more to consume it within the WebIDE?
Even after I could install it through the client, I get the same error:
npm ERR! node v4.4.0
npm ERR! npm v2.14.20
npm ERR! code E404
XSA Client
npm install squel@4.4.1
