Stop Losing Code: Essential Git Tips
Small, focused Git commits are the backbone of good version control. When you cram multiple unrelated changes into a single commit, you sacrifice clarity and make debugging harder. This guide covers four essential Git practices that keep your code safe, your history clean, and your peace of mind intact.
1 Commit small, focused changes
Each commit should solve one problem or add one feature. Instead of a giant commit like "update app and fix bugs," split it into "fix login button alignment" and "refactor API service." A good rule of thumb: if you need the word "and" in your commit message, you're probably bundling too much. Small commits are easier to review, easier to revert if something goes wrong, and leave a clear trail in your git log that actually makes sense six months later.
2 Always check your status first
Before you commit anything, run `git status` to see exactly what's staged, unstaged, or untracked. This simple step prevents embarrassing mistakes—like committing debug code, node_modules, or API keys you forgot to clean up. Beyond `git status`, run `git diff` to see the actual line changes in your staged files; sometimes your eyes will catch a typo or mistake the git interface hides. Make this a habit: status before every commit.
3 Isolate features with branches
Never commit directly to your main branch. Instead, create a feature branch with `git checkout -b feature-name`, do your work there, and merge back to main only when it's tested and ready. Branches let you experiment safely, work on multiple features in parallel, and keep your main branch clean and deployable at all times. Switching between branches is quick: just run `git checkout branch-name` to hop back and forth as needed.
4 Undo mistakes safely with restore
If you've edited a file but haven't committed it yet, `git restore <file>` reverts it to the last committed state. If you've already committed something you want to undo, use `git reset --soft HEAD~1` to undo the commit but keep your changes staged and ready to edit. The key difference: restore erases changes, reset keeps them. For safety, always use soft reset first—it gives you a chance to review what you're undoing.
These four practices form a safety net around your code. Small, focused commits make it easy to find and fix bugs. Branches keep main stable. Status checks and restore/reset commands let you recover gracefully when mistakes happen. Master these habits early, and you'll never again lose days of work to a bad commit or a careless git command.
