I want to do something like this, so npm install also installs the package.json of ../somelocallib or more importantly its dependencie
This is how you will add local dependencies:
npm install file:src/assets/js/FILE_NAME
Add it to package.json from NPM:
npm install --save file:src/assets/js/FILE_NAME
Directly add to package.json like this:
....
"angular2-autosize": "1.0.1",
"angular2-text-mask": "8.0.2",
"animate.css": "3.5.2",
"LIBRARY_NAME": "file:src/assets/js/FILE_NAME"
....
