Git Best Practices for Teams: A Comprehensive Guide

Git Best Practices for Teams: A Comprehensive Guide
Learn essential Git practices that will help your team collaborate effectively, maintain code quality, and streamline development workflows.

Understanding Git Workflow

  1. Branching Strategy 
main
├── develop
│   ├── feature/user-auth
│   ├── feature/payment
│   └── hotfix/security-patch
└── release/v1.0.0
Enter fullscreen mode Exit fullscreen mode

Main Branches
main: Production-ready code
develop: Integration branch for features
Supporting Branches
feature/: New features
bugfix/: Bug fixes
hotfix/: Urgent production fixes
release/: Release preparation
Best Practices

  1. Commit Messages 
# Good commit message
feat(auth): implement OAuth2 authentication

- Add Google OAuth2 integration
- Implement JWT token handling
- Add user session management

# Bad commit message
fixed stuff and added things

Commit Message Structure
Type: feat, fix, docs, style, refactor, test, chore
Scope: Component or feature affected
Subject: Brief description
Body: Detailed explanation
Footer: Breaking changes, issue references

  1. Branch Naming 
# Feature branches
feature/user-authentication
feature/payment-gateway

# Bug fixes
bugfix/login-error
bugfix/payment-validation

# Hotfixes
hotfix/security-vulnerability
hotfix/critical-error
Enter fullscreen mode Exit fullscreen mode
  1. Code Review Process Before Review 
# Update your branch
git fetch origin
git rebase origin/develop

# Clean up commits
git rebase -i HEAD~3
Enter fullscreen mode Exit fullscreen mode

Review Checklist

Code follows style guide
Tests are included
Documentation is updated
No sensitive data
Performance considered

  1. Merge Strategies
  2. Merge Commits 
git checkout develop
git merge feature/new-feature
Enter fullscreen mode Exit fullscreen mode
  1. Rebase and Merge 
git checkout feature/new-feature
git rebase develop
git checkout develop
git merge feature/new-feature --ff-only
Enter fullscreen mode Exit fullscreen mode
  1. Squash and Merge 
git checkout develop
git merge --squash feature/new-feature
git commit -m "feat: implement new feature"
Enter fullscreen mode Exit fullscreen mode


Team Collaboration

  1. Pull Request Template 
## Description
[Describe your changes]

- [ ] Documentation
- [ ] Performance improvement

## Testing
- [ ] Unit tests added
- [ ] Integration tests added
- [ ] Manual testing completed

## Screenshots
[If applicable]

## Checklist
- [ ] Code follows style guide

  1. Code Review Guidelines What to Review

Code quality
Test coverage
Documentation
Security concerns
Performance impact
How to Review

Be constructive
Explain reasoning
Suggest alternatives
Check for edge cases

  1. Conflict Resolution 
# When conflicts occur
git fetch origin
git rebase origin/develop

# Resolve conflicts in files
git add <resolved-files>
git rebase --continue

# If rebase gets complicated
git rebase --abort
Enter fullscreen mode Exit fullscreen mode

Advanced Practices

  1. Git Hooks 
# pre-commit hook
#!/bin/sh
npm run lint
npm run test

# commit-msg hook
#!/bin/sh
npx commitlint --edit $1
Enter fullscreen mode Exit fullscreen mode

  1. Git Aliases 
# Add to .gitconfig
[alias]
    st = status
    co = checkout
    br = branch
    ci = commit
    unstage = reset HEAD --
    last = log -1 HEAD
Enter fullscreen mode Exit fullscreen mode
  1. Git Workflow Automation 
# .github/workflows/pr.yml
name: Pull Request Checks
on: [pull_request]
jobs:
  lint:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Run linter
        run: npm run lint
Enter fullscreen mode Exit fullscreen mode

Security Best Practices

1. Sensitive Data
# .gitignore
.env
*.pem
config/secrets.yml
Enter fullscreen mode Exit fullscreen mode
  1. Access Control Branch Protection

Require reviews
Require status checks
Require signed commits
Key Management

Use SSH keys
Rotate keys regularly
Use deploy keys
Performance Optimization

  1. Repository Size 
# Clean up repository
git gc
git prune
git repack -a -d --depth=250 --window=250
Enter fullscreen mode Exit fullscreen mode
  1. Large File Handling 
# Use Git LFS
git lfs install
git lfs track "*.psd"
git lfs track "*.zip"
Enter fullscreen mode Exit fullscreen mode

Common Issues and Solutions

  1. Accidental Commits 
# Remove last commit
git reset --soft HEAD~1

# Remove file from commit
git reset HEAD~1 <file>
git checkout -- <file>
Enter fullscreen mode Exit fullscreen mode
  1. Lost Changes 
# Recover lost commits
git reflog
git checkout <commit-hash>

# Recover stashed changes
git stash list
git stash apply stash@{0}
Enter fullscreen mode Exit fullscreen mode
