npm install from bare git file repo

Question

how can I install an npm module from a bare git repo folder?

So I have a folder that contains a git repo. It was created with git init --bare. Now I want npm to fetch the latest version of the master branch, and there a package.json file is avaliable.

What is the right way to do this?

I tried stuff like:

npm install git+file:///W:/my/git/repo/ -g
npm install git+file:///W:/my/git/repo/#master -g
npm install file:///W:/my/git/repo/ -g --from-git

Is it even possible?

Answer 1

I have a hacky answer, which might be better than no answer at all. Use Git's URL rewriting feature:

git config --global url.file://.insteadOf git+file://
npm install git+file:///c:\dev\code\mymod

It generates warnings about not being able to fetch remotes, etc., but it installs the module and npm exits with a success code.

This works because the git+ prefix makes NPM pass the whole path to Git, and then the URL rewrite rule turns git+file:// (an invalid Git protocol string) into file:// (a valid Git protocol string).
