Breaking Change#

Atomic Commits#

Atomic commits contain a single logical change to your codebase. This practice makes it easier to understand changes, revert if needed, and maintain a clean history.

Good Practices#

            - ✓

                One logical change per commit
            - ✓

                All tests pass with each commit
            - ✓

                Clear, focused commit messages

Bad Practices#

            - ✗

                Multiple unrelated changes
            - ✗

                Mixing refactoring with features
            - ✗

                Vague commit messages

Commit Organization Tips#

            - 1.

Use Interactive Staging#

Use git add -p to stage specific parts of files, enabling more granular commits.

$ git add -p

            - 2.

Review Changes Before Committing#

Always review staged changes before committing.

$ git diff --staged

            - 3.

Fix Up Commits During Development#

Use --fixup to mark commits as fixes to previous ones.

$ git commit --fixup=HEAD~1
