How to Write Better Commits and Pull Requests for Clean and Scalable Projects

How to Write Better Commits and Pull Requests for Clean and Scalable Projects

When a team’s Git history is chaotic, collaboration becomes painful, code reviews get slower, and releases are harder to manage.

On the other hand, clear commits and well-structured pull requests build trust, speed up teamwork, and prepare your project for real scalability.

This article explains how to write better commits and pull requests — with concrete examples, professional practices, and real reasoning behind every rule.

If you want your projects to be clean, scalable, and contributor-friendly, this guide is for you.

Why It Matters: Beyond “Just Following Rules”

Understandable history: Good commits act as a living documentation.
Efficient teamwork: Pull requests are easier to review and merge.
Reliable automation: Changelogs, releases, and CI/CD pipelines depend on well-structured commits and PRs.
Professional image: Whether you work in open-source, freelancing, startups, or corporations, a clean workflow reflects your engineering standards.

Good commits and pull requests are not bureaucracy.

They are an investment in the long-term quality and speed of your project.

1. How to Write Effective Commit Messages

The Structure You Should Use

Follow the Conventional Commits format:

type(scope): [module] short description

Where:

type: The type of change (feat, fix, docs, etc.).
(scope): The part of the project (optional but recommended) like api, web, auth, dashboard.
[module]: The feature or topic touched by the change.
short description: A simple, imperative sentence starting with a verb ("add", "fix", "improve", "refactor", …) — no period at the end.

Good Examples:

feat(web): [authentication] add login form validation
fix(api): [user-service] resolve user timezone conversion

Bad Examples (too vague and useless for your future self or teammates):

update code
fix
working on something

Standard Types You Should Use

Type	Meaning
`feat`	Adding a new feature
`fix`	Fixing a bug
`docs`	Documentation changes only
`style`	Formatting changes (no logic change)
`refactor`	Code restructuring without behavior change
`test`	Adding or updating tests
`chore`	Maintenance tasks (builds, tooling)
`ci`	Changes to CI/CD pipelines
`build`	Build system or dependency changes
`perf`	Code changes that improve performance
`revert`	Revert a previous commit
`deps`	Updating dependencies

These types make your Git history easier to filter, automate, and understand.

Practical Commit Writing Tips

Start with a verb: “add”, “fix”, “improve”, “refactor”, “remove”, “update”.
Make each commit focused: One change = One commit.
No WIP commits in main branches (main, develop).
Explain why if necessary: Small clarification in the body of the commit is okay.
Use clear, neutral English — avoid slang or jokes.

Example with a body:

refactor(api): [user-service] simplify timezone handling

Remove duplicated timezone conversion logic.  
Use built-in Date API instead of manual parsing.

2. How to Write Effective Pull Requests

A pull request is not just code. It is a conversation and a story.

Treat it seriously, and you will speed up reviews, avoid misunderstandings, and improve team velocity.

Pull Request Title Structure

Follow this format:

[Type]-APP-#Issue short description

[Type]: Type of change (capitalized) [Feat], [Fix], [Docs], etc.
APP: Major part of the project: WEB, API, MOBILE, DESKTOP, etc.
#Issue: The issue number related to this PR.
short description: Simple, clear, action-driven sentence.

Examples:

[Feat]-WEB-#1234 add user profile editing page
[Fix]-API-#1250 fix incorrect password reset tokens

Pull Request Description Template

Always fill your PR description properly:

### What was done
- Implemented user profile editing page
- Added form validation and error handling

### Related issue
Closes #1234

### How to test
- Go to `/profile/edit`
- Try updating your name and profile picture
- Submit invalid data to see validation errors

### Additional notes
- No database migrations needed

3. Best Practices for Commits and PRs

1. Small, Focused Commits

Each commit should represent one logical change.

Split your work if necessary. This makes reviewing, reverting, or debugging much easier.

2. Small and Clear Pull Requests

Ideal pull request size: ~300–500 lines changed.

Big PRs are harder to review and more prone to bugs.

If your PR is getting too big:

Split into smaller PRs.
Clearly explain why if you must keep it big.

3. Link Related Issues

Always link your PR to its related issues using keywords like Closes #1234 or Fixes #1250.

This keeps tracking automatic in GitHub, GitLab, Bitbucket, etc.

4. Keep Descriptions Professional and Practical

No jokes or vague comments in commit or PR descriptions.

Assume that someone you don’t know — your future teammates or even future you — will read these commits and PRs.

Stay clear, neutral, and professional.

5. Use Tools That Enforce Good Practices

Commitlint + Husky: Force commit message conventions.
Conventional Commits: Standardize commit types.
Semantic Release: Automate versioning based on commits.
Prettier, ESLint: Keep code clean before even pushing it.

Good tools make good practices automatic.

Discipline = Speed + Quality

Writing good commits and pull requests is not a waste of time —

it’s what makes professional software development faster, safer, and more scalable.

If you want to:

Be a developer people enjoy working with
Maintain clean codebases without fear
Ship faster with fewer bugs
Contribute easily to serious open-source projects

Start today: Write every commit and pull request as if you were reviewing it 6 months from now.
