• Semantic Commit Messages See how a minor change to your commit message style can make you a better programmer.

  Format: ():

  is optional

  • Example

              feat: add hat wobble
      ^--^  ^------------^
      |     |
      |     +-> Summary in present tense.
      |
      +-------> Type: chore, docs, feat, fix, refactor, style, or test.
  

• More Examples:

  • feat: (new feature for the user, not a new feature for build script)
  • fix: (bug fix for the user, not a fix to a build script)
  • docs: (changes to the documentation)
  • style: (formatting, missing semi colons, etc; no production code change)
  • refactor: (refactoring production code, eg. renaming a variable)
  • test: (adding missing tests, refactoring tests; no production code change)
  • chore: (updating grunt tasks etc; no production code change)
