Best Practices for Git and Git Workflow

Git is the backbone of modern software development. Whether you work solo or in a large team, understanding how to structure your Git workflow can mean the difference between effortless collaboration and daily merge conflicts.

This guide covers Git workflows, branching strategies, merge vs rebase, and best practices for maintaining clean, reliable repositories.

🔧 Why a Good Git Workflow Matters

A well-structured Git workflow provides:

Consistency — Everyone follows the same conventions.
Traceability — Every change is easy to understand and revert.
Collaboration — Merging, reviewing, and deploying code is frictionless.
Stability — Production code remains stable while development moves fast.

🧭 Common Git Workflows

Different teams adopt different workflows depending on project scale and CI/CD maturity.

Feature Branch Workflow

Ideal for small to medium projects.

# create a new branch for your feature
git checkout -b feature/user-auth

Once your feature is complete:

git push origin feature/user-auth
# open a pull request to main/develop branch

Pros	Cons
Clean, isolated work.	Requires discipline to delete merged branches.
Easy code reviews.

Gitflow Workflow

A structured approach with dedicated branches:

main — production-ready code
develop — integration branch for new features
feature/* — new features
release/* — pre-production testing
hotfix/* — emergency fixes

gitGraph
    commit id: "Init"
    branch develop
    commit id: "Feature A"
    branch feature/login
    commit id: "Work on login"
    checkout develop
    merge feature/login
    branch release/1.0
    commit id: "Prep release"
    checkout main
    merge release/1.0
    commit id: "Hotfix"
    branch hotfix/1.0.1
    commit id: "Fix issue"
    checkout main
    merge hotfix/1.0.1

Pros	Cons
Great for larger teams or staged deployments.	Can feel heavy for smaller teams.
Clear separation of production and development work.	Requires discipline to delete merged branches.

Trunk-Based Development

A modern, CI/CD-friendly approach.

Developers branch off main (short-lived branches)
Frequent commits and merges (often daily)
Automated tests ensure stability

git checkout -b feat/add-search
# work fast, commit often, merge quickly

Pros	Cons
Encourages fast iteration and continuous delivery.	Requires robust testing and CI pipelines.
Reduces long-lived branch drift.

⚔️ Merge vs Rebase

Two powerful ways to integrate changes — each with tradeoffs.

🔹 `git merge`

Merges one branch into another, preserving history.

git checkout main
git merge feature/auth

Creates a merge commit, which explicitly records branch history.

🔹 `git rebase`

Moves (or “replays”) commits on top of another branch.

git checkout feature/auth
git rebase main

This rewrites history, making it look like all work happened sequentially.

When to use merge vs rebase

When to use merge	When to use rebase
Working in teams	Working solo
Keep branch history visible	You want a linear commit history
You want accurate audit trail	You prefer linear, simplified history

🧠 Best Practices for Git Excellence

Category	Recommendation
Commit Messages	Write concise, meaningful messages (e.g., `fix: handle null user` or `feat: add search filters`).
Branch Naming	Use clear, consistent names like `feature/`, `fix/`, `chore/`, `docs/`.
Pull Requests	Keep PRs small and focused — easier to review and test.
Reviews	Use PR templates to enforce consistency and quality.
Releases	Tag versions (e.g., `v1.0.3`) and use `CHANGELOG.md`.
Automation	Add pre-commit hooks (e.g., lint, test) using Husky or Lefthook.
Clean-up	Delete merged branches regularly.

🪄 Pro Tips from Real Projects

Squash commits before merging: Keeps history clean and meaningful.
```
git rebase -i HEAD~3
```
Use git stash wisely: To save uncommitted work temporarily.
```
git stash push -m "WIP: login refactor"
```

Leverage Git aliases: Speed up your workflow. Example in ~/.gitconfig:

[alias]
  st = status
  co = checkout
  cm = commit -m
  lg = log --oneline --graph --decorate

Protect your main branch: Enforce PR reviews and passing CI checks before merge.

🧩 Final Thoughts

There’s no one-size-fits-all Git workflow. Your ideal setup depends on your team size, release cadence, and deployment process.

Small teams → Feature branch or Trunk-based
Large teams → Gitflow
Fast CI/CD setups → Trunk-based with frequent merges

The goal is clarity, collaboration, and stability — not just fancy branching.
