git-under

Basic git client in JavaScript created for educational purposes.

Supports:

• init
• add <path/to/file.txt>
• commit <message>
• cat-file <type> <hash>
• log
• branch [name]
• checkout <branch|hash>
• push <url> - pushing also requires the NDR_USERNAME and NDR_PASSWORD environment variables to hold the credentials for the remote repository
• objects-delta <descendant-hash> <ancestor-hash> - computes the difference of objects reachable from two commits. This is used to push data upstream.

See the scripts in tools for use examples.

Objects follow the git format; index and HEAD do not.

Loosely follows previous efforts like pygit and gitlet.
