Retrieve the Git SHA of the latest commit that touched any number of files. Useful in particular with bundling, when you want to identify a collection of files by something like a hash, but tied to something more real (like a Git history.)
Install using npm:
npm install git-bundle-sha
And then require:
var gitsha = ;
Don't read any values from cache (some things, like the submodule list, are cached for performance.) Default =
Trim the resulting SHA to a specified length. Default =
null (no trimming.)
This works by sub-shelling out to a Git process, so your node process must be able to access git. This also means that it is tied to your project directory at the moment.
Yes. If you are using submodules, any file nested under that submodule directory will have a last-modified SHA that corresponds to the commit that last updated the submodule in the parent project.
