WHAT

What Are Branches and Commits?

Think of your codebase as a story being written by multiple authors simultaneously. Commits are the individual sentences that capture each meaningful change, while branches are parallel storylines that let you experiment without affecting the main narrative. Together, they form the foundation of modern software development.

According to the official Pro Git Book, every time you perform a commit, you’re recording a snapshot of your project that you can revert to or compare to later. A commit message is descriptive text added to the commit object by the developer who made the commit, providing context for what changed and why.
COMMITS
Your Project's Checkpoints

Understanding Commits

A commit in Git is essentially a snapshot of your repository at a specific point in time. According to Nile Bits’ development workflow guide, each commit represents a set of changes made to files in the repository, with a unique identifier (SHA-1 hash), author information, timestamp, and commit message. Commits serve as an archive of changes—they can become an ancient manuscript to help us decipher the past and make reasoned decisions in the future.

Key components of a commit:

  • Hash (ID): A unique 40-character SHA-1 identifier (e.g., `a3c7f12`)
  • Author: Who made the changes
  • Date/Time: When the commit was created
  • Message: Description of what changed and why
  • Content: The actual file changes (diff)
BRANCH
Parallel Development Paths

Understanding Branches

According to Shreyas Matade’s analysis on Git branching, branching refers to the creation of separate lines of development within a code repository. The creation of a branch essentially takes a snapshot of your project’s current state, allowing you to explore new features, fix bugs, or test experimental ideas without disrupting the main codebase.

As described in Nile Bits’ guide, a branch is a separate line of development within a repository that allows multiple developers to work on different features or fixes simultaneously without interfering with each other’s changes. Each branch exists as an independent workspace where developers can make changes, commit new code, and monitor the progress of specific tasks or features.

The Business Case

Why Branches and Commits Matter

For Business Leaders

Understanding branches and commits isn’t just technical jargon—it directly impacts your bottom line and product quality. According to GitKraken’s branching strategy guide, Git helps developers collaborate on code with teammates, and combining powerful features like commits and branches with specific principles and strategies helps teams organize code and reduce the time needed to manage versioning.
 
Business benefits
  • Risk Mitigation
    Branches provide a safety net—production code remains stable while new features are developed
  • Faster Time-to-Market
    Multiple teams can work simultaneously without blocking each other
  • Quality Assurance
    Every change is tracked and can be reviewed before deployment
  • Audit Trail
    Complete history of who changed what and when, crucial for compliance
  • Cost Savings
    Bugs can be traced to specific commits, dramatically reducing debugging time

For Development Teams

According to daily.dev’s Git best practices guide, commit messages are helpful because they record the changes made to a project and explain why these changes were needed. This not only makes troubleshooting easier but also helps team members stay updated on each other’s work.
 
Technical benefits
  • Parallel Development
    Team members work independently without conflicts
  • Experimentation
    Try new approaches without risk to stable code
  • Code Review
    Changes can be reviewed before integration
  • Rollback Capability
    Instantly revert to any previous state
  • Context Preservation
    Future developers understand the reasoning behind changes
WHEN
Strategic Timing

When to Create Branches

Feature Development
Every new feature should live on its own branch. According to Eduonix’s version control best practices, by creating a new branch for each task or feature, you can work independently without interfering with others’ work. A branch should ideally represent a single logical change.
 
When to branch for features
  • Adding new functionality that takes more than a few hours
  • When multiple related commits will be needed
  • Before starting work that might be experimental
  • When you need code review before merging
Bug Fixes
According to DEV Community’s Git branch best practices, you can create topic branches for each bugfix you are working on. It works the same way as making a branch for a feature, except that these branches usually have a smaller number of commits.
Hotfixes for Production
According to Vincent Driessen’s successful Git branching model, hotfix branches are very much like release branches in that they are also meant to prepare for a new production release, albeit unplanned. They arise from the necessity to act immediately upon an undesired state of a live production version.
Experimental Work
Create experimental branches when testing risky refactoring, trying new architectural approaches, or exploring alternative solutions—if the experiment succeeds you can merge it, and if it fails you simply delete the branch without affecting your stable codebase.
WHEN
The Art of Meaningful Snapshots

When to Commit

Commit Frequency: Finding the Balance
According to GitLab’s best practices guide, committing code in small batches decreases the likelihood of integration conflicts and makes testing easier. Each commit should represent one logical change—whether a feature addition, bug fix, or improvement.
When to commit
  • After completing a discrete unit of work (function, fix, feature component)
  • Before switching to a different task
  • At the end of your work session
  • After making code that compiles and passes tests
  • When you want to save a checkpoint before trying something risky
When NOT to commit
  • Broken or incomplete code on shared branches
  • Code that doesn't compile
  • Untested changes to critical systems
  • Multiple unrelated changes together

Commit Messages: Writing for Humans and Machines

Conventional Commits is a lightweight convention for commit messages. It provides a set of rules for adding human-and machine-readable meaning to commit messages, making it easier to create automated tools on top of commit messages.
The Conventional Commits format
💻 
<type>[optional scope]: <description>

[optional body]

[optional footer(s)]
Common commit types
According to Graphite’s commit message guide and multiple sources, the most common commit types are:
  • feat: A new feature for the user
  • fix: A bug fix for the user
  • docs: Documentation changes only
  • style: Code style changes (formatting, missing semicolons)
  • refactor: Code restructuring without changing behavior
  • test: Adding or updating tests
  • chore: Maintenance tasks (dependencies, build configs)
  • perf: Performance improvements
  • build: Changes affecting the build system
  • ci: CI/CD pipeline changes
The Conventional Commits format
💻 
// Excellent commit message examples

// 1. Simple feature addition
git commit -m "feat(auth): Add two-factor authentication support"

// 2. Bug fix with context
git commit -m "fix(api): Resolve rate limiting causing 429 errors

The rate limiter was counting requests per IP instead of per user,
causing mobile users sharing IPs to hit limits prematurely.

Changed to user-based rate limiting with Redis cache.

Closes #456"

// 3. Breaking change
git commit -m "feat(api)!: Change authentication endpoint to use JWT

BREAKING CHANGE: The /api/auth endpoint now returns JWT tokens
instead of session cookies. Clients must update to include
Authorization: Bearer <token> header in all API requests.

Migration guide: docs/migration/v2-auth.md"

// 4. Performance improvement
git commit -m "perf(db): Add indexes to frequently queried columns

Added composite index on (user_id, created_at) for posts table.
Reduced query time from 2.3s to 45ms on posts listing endpoint.

Benchmark results in PR #567"

// 5. Refactoring
git commit -m "refactor(payment): Extract validation logic into separate module

No functional changes. Moved payment validation from controller
to dedicated validator class for better testability and reuse."

The 50/72 Rule

According to Baeldung’s Git commit best practices and freeCodeCamp’s commit guide, commit message formatting follows the 50/72 rule:
  • Subject line: Maximum 50 characters
  • Body lines: Wrapped at 72 characters
  • Imperative mood: Write as if giving a command (e.g., "Add" not "Added")
The Conventional Commits format
💻 
# Good structure
git commit -m "feat(payment): Add Stripe webhook handler" \
           -m "Implements webhook endpoint to process payment events
from Stripe. Handles successful payments, failures, and
refunds with appropriate status updates in database.

Validates webhook signatures using Stripe secret key.
Adds retry logic for failed database updates.

Related to #234"
Why these rules matter
According to Initial Commit’s best practices guide, these limits were established based on analyzing good practices in relevant projects. For example, commit messages in the Linux kernel have titles that summarize changes well, usually using around 50 characters. The widely accepted standard for readable line length is 80 characters, contributing to the 72-character body limit.

Branch Naming Conventions

According to Medium’s Git Good guide by Shinjith P R, descriptive branch names give immediate context for their purpose. Prefixing branches helps to organize them according to their purpose, improving clarity and helping to automate workflows.
Standard Branch Naming Patterns
💻 
# Feature branches
feature/user-authentication
feature/JIRA-123-payment-integration
feature/dark-mode-support

# Bug fix branches
bugfix/login-timeout
bugfix/PROJ-456-memory-leak
fix/email-validation-regex

# Hotfix branches
hotfix/critical-security-patch
hotfix/production-crash-fix

# Release branches
release/v1.2.0
release/2024-Q1

# Experimental branches
experiment/react-migration
experiment/new-caching-strategy
Branch naming best practices:
According to DEV Community and Medium’s guides:
  • Use separators
    Use hyphens (`-`) or slashes (`/`) for readability
  • Include ticket numbers
    Reference issue trackers (e.g., `feature/JIRA-123-description`)
  • Be descriptive
    Name should indicate purpose at a glance
  • Keep it concise
    Short but meaningful (avoid excessive length)
  • Use lowercase
    Consistency across team members
  • Avoid special characters
    Stick to alphanumeric and hyphens

Building Better Software Through Better Practices

Branches and commits are not just technical features of Git—they’re fundamental practices that separate professional software development from chaotic coding. According to the Pro Git Book, commits serve as checkpoints that you can revert to or compare to later, while branches enable parallel development without interference.

The key takeaways for 2026:
  • For commits
    Write clear, conventional messages that explain what changed and why. Commit frequently but meaningfully. Each commit should tell a story that future developers (including yourself) will understand.
  • For branches
    Use them liberally for every feature, fix, and experiment. Choose a branching strategy that fits your team's size and deployment frequency. Keep branches short-lived and focused.
  • For teams
    Establish clear conventions and stick to them. Use pull requests for code review. Automate checks with CI/CD. Communicate about overlapping work to prevent conflicts.
Remember the words from the Conventional Commits specification: the goal is to make commit messages human-and machine-readable, enabling automated tools while maintaining clarity for developers. Whether you choose Git Flow’s structure, GitHub Flow’s simplicity, or Trunk-Based Development’s speed, the important thing is consistency and clear communication.

Start small—improve your commit messages today, create a branch for your next feature tomorrow, and gradually adopt more advanced practices as your team grows. The investment in learning these practices pays exponential dividends in code quality, team productivity, and project maintainability.

Commits serve as an archive of changes. They can become an ancient manuscript to help us decipher the past, and make reasoned decisions in the future.

FAQ's

Frequently Asked Questions

According to GitLab's best practices and Eduonix's version control guide, commit early and commit often, but ensure each commit represents one logical change. Commit after completing a discrete unit of work such as a function, a fix, or a test. According to the Enlume blog on Conventional Commits, each commit should represent a single, focused change—breaking down complex tasks into smaller, atomic commits makes it easier to understand the history of the codebase, isolate issues, and perform effective code reviews. However, avoid committing broken or incomplete code to shared branches. If working alone on a feature branch, commit frequently even for work-in-progress to save your progress.

The choice depends on your deployment frequency and team structure. According to Graphite's branching strategies guide, consider team size (smaller teams benefit from GitHub Flow or Trunk-Based Development, while larger teams might prefer Git Flow), deployment frequency (frequent releases align well with GitHub Flow, while infrequent releases suit Git Flow), and project complexity (simple projects thrive on GitHub Flow, while complex projects may require Git Flow). GitKraken notes that there is not a one-size-fits-all Git branch strategy—you should choose based on your team's environment, product, and specific development needs, and you can optimize it with further modifications.

According to Eduonix's guide, rebasing your feature branch onto the latest main branch can help create a cleaner, linear history compared to using git merge. Rebasing re-applies your commits on top of the latest changes, avoiding unnecessary merge commits. Merge preserves the complete history including when branches diverged and converged, creating merge commits that show the integration points. Rebase rewrites history by replaying your commits on top of another branch, creating a linear history. However, never rebase commits that you've already shared with others, as it rewrites history and can cause confusion for collaborators. Use merge for shared branches and public history; use rebase for cleaning up local branches before pushing.

According to the Conventional Commits specification and multiple best practice guides, focus on using simple, clear language with the standard format. The Conventional Commits format helps by providing structure: `<type>(<scope>): <description>`. Use imperative mood (Add, Fix, Update) rather than past tense. Keep the subject line short and factual (what changed). Use translation tools if needed, but prioritize clarity over perfect grammar. Your team will appreciate consistent formatting and clear descriptions of what changed more than perfect English. Many successful open-source projects have contributors from around the world writing clear, effective commit messages in simple English.

According to GitKraken and GitHub Flow principles, delete branches immediately after they're successfully merged to keep your repository clean. The general rule is to delete a branch when it has served its purpose and its commits are safely integrated into the main branch. For feature branches, delete after merging to main or develop. For release branches in Git Flow, delete after merging to both main and develop. For hotfix branches, delete after deploying the fix and merging back to necessary branches. For experimental branches, delete if the experiment was unsuccessful or after merging if successful. You can always recover deleted branches using git reflog if needed, so don't worry about losing work. Most platforms like GitHub and GitLab offer options to automatically delete branches after pull request merges.
