• Convential commits

  Conventional Commit is a formatting convention that provides a set of rules to formulate a consistent commit message structure.

  Structure:

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

  The commit type can include the following:

  • feat – a new feature is introduced with the changes
  • fix – a bug fix has occurred
  • chore – changes that do not relate to a fix or feature and don’t modify src or test files (for example updating dependencies)
  • refactor – refactored code that neither fixes a bug nor adds a feature
  • docs – updates to documentation such as a the README or other markdown files
  • style – changes that do not affect the meaning of the code, likely related to code formatting such as white-space, missing semi-colons, and so on.
  • test – including new or correcting previous tests
  • perf – performance improvements
  • ci – continuous integration related
  • build – changes that affect the build system or external dependencies
  • revert – reverts a previous commit
