[RRFC] Share Dependencies source in one folder across all projects

Share Dependencies source in one folder like Maven, instead of repetitive node modules folder in all projects.

Maven has ./m2/repository/ directory which has all maven dependencies sources which downloaded from maven repo website classified by package name and version.

Maven has pom.xml file which equivalent to package.json file in node, If any project depending on any dependency during build or development phase, it will be collected from the shared local repo folder otherwise it will be pulled from website to local repo .

so it would be better if NPM support that instead of installing same dependencies sources in local folder node_modules for all projects !!

there are many dependencies which has large size like angular and electron , why should I duplicate the same dependencies sources in all projects which I have , also why should I download all files each time I run npm install !! .

Shared repo folder will save time and resources for us as a developers.

Start by reviewing how npm currently installs dependencies into each project's node_modules directory and how package.json expresses those dependencies. Compare the requested behavior with Maven's shared m2/repository model. Done should mean dependencies can be reused across projects without repeated downloads or duplicated local sources.
