Using npm behind firewall using Visual Studio 2015

I try to utilize the new npm support in Visual Studio 2015, but are hitting some problems. I'm located behind a corporate firewall.

I have tried to add "grunt" from the package.json file, and can see this output related to npm.

I have seen some posts where you can configure node to ignore SSL, but don't know how to do this in Visual Studio 2015.

Please help Best regards, Thomas

Following steps will work for VS 2015

1- Run command prompt as Administrator

2- go to Path of External tools for VS 2015 in your case it is " C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\Microsoft\Web Tools\Editors

3- npm config set ca=""

4- npm config set strict-ssl false

5- npm install npm -g --ca=null

In my case the above solution did not work. It worked after updating .npmrc file and when running npm with a help of Fiddler. Here are the steps that worked for me:

After installed npm, update .npmrc file located in C:\Users\'username' directory:

registry=http://registry.npmjs.org

proxy=http://127.0.0.1:8888

https-proxy=http://127.0.0.1:8888

http-proxy=http://127.0.0.1:8888

strict-ssl=false

Open Fiddler, and under 'Rules' tab select 'Authomatically Authenticate'. Lets not forget Fiddler listens on port 8888
While having Fiddler open, the npm command shouwl work just fine within Visual Studio

This should work behind corporate firewall, with domain joined systems.
