Git Commit Message Convention


Status: decay

Conventional Commits is a convention for adding human and machine readable meaning to commit messages.


  • Improves a team's shared understanding of a codebase by better communicating what a commit did through:
    • structure,
    • clarity (through use of keywords) and
    • consistency.
  • Makes it easier to write automated tools on top of:
    • automatically generating CHANGELOGs,
    • automatically determining a semantic version bump (based on the types of commits landed) and
    • triggering build and publish processes based on commit type.


The convention structures a commit with 2 mandatory fields and 3 optional.

> <type>[scope]: <description>
> [body]
> [footer(s)]_

> git commit -m "fix: broken home link"_
