Project history

Richard Kotze published the Git Mob repository in February 2018. The repository is organized as a workspace, with the Git Mob CLI package and a shared git-mob-core package for reusable co-author logic.

The changelog shows the CLI growing from a simple co-author helper into a TypeScript and Node-based toolchain. The 2.x line integrated git-mob-core for core features; 3.0.0 moved to ESM and Node 16; 4.0.0 completed a TypeScript migration for main files and removed lower-value edit/delete commands.

Adoption history

Git Mob follows the adoption of GitHub's `Co-authored-by` commit trailers, which make commits visible as co-authored on GitHub. The tool packages that convention for teams that pair or mob frequently, reducing the friction of remembering names, emails, and trailer formatting.

Its distribution is centered on npm and Homebrew, with a related Visual Studio Code extension and a reusable core package. That makes it especially relevant to JavaScript-heavy teams and collaborative coding shops that switch between terminal and editor workflows.

How it is used

Users configure their primary Git author normally, store teammates in `.git-coauthors`, then run commands such as `git mob ad bd` to select co-authors by initials. Subsequent commits include `Co-authored-by` trailers; `git solo` returns to a solo author flow.

The CLI can add co-authors, suggest co-authors from repository history, print the active mob, fetch GitHub no-reply author details when enabled, and support commit-message hooks for users who commit with `git commit -m`.

Why package nerds care

Git Mob is package-nerd interesting because it turns a social collaboration convention into a Git subcommand and a tiny local data file. It also shows how a CLI can bridge Git config, commit templates, npm packaging, Homebrew packaging, and editor extensions without needing a server.
