Team collaboration standards and commit message standards are indispensable parts of front-end development. Good collaboration standards can improve team efficiency and reduce communication costs, while standardized commit messages facilitate code review, issue tracking, and version management. The following content will delve into these two aspects in detail.

Team Collaboration Standards

Unified Code Style

Team members should adhere to a unified code style, including indentation, naming, comments, etc. Tools like ESLint and Prettier can be used for automatic code formatting.

// Bad example
function getUserInfo(userId){return fetch(`/api/users/${userId}`).then(res=>res.json())}

// Good example
function getUserInfo(userId) {
  return fetch(`/api/users/${userId}`)
    .then((res) => res.json());
}

Branch Management Strategy

Adopt Git Flow or a similar branch management strategy:

main/master: Production code
develop: Development branch
feature/xxx: Feature branch
hotfix/xxx: Hotfix branch

# Example of creating a feature branch
git checkout -b feature/user-authentication develop

Code Review Process

All code changes must go through a Pull Request review:

Developers complete work on a feature branch.
Create a PR to the target branch (usually develop).
At least one team member must approve before merging.
Resolve review comments before merging the branch.

Documentation Standards

Each project should include:

README.md: Project overview, environment setup, startup commands.
CHANGELOG.md: Version change history.
API.md: API documentation (if backend interaction exists).

Commit Message Standards

Commit Message Structure

Follow the Conventional Commits specification:

<type>(<scope>): <subject>
<blank line>
<body>
<blank line>
<footer>

Commit Types (type)

Common types include:

feat: New feature.
fix: Bug fix.
docs: Documentation changes.
style: Code style adjustments.
refactor: Code refactoring.
test: Test-related changes.
chore: Build process or auxiliary tool changes.

Examples

# Feature commit example
git commit -m "feat(user): add login functionality

- implement email/password login
- add form validation
- setup auth store

Closes #123"

# Bug fix example
git commit -m "fix(api): handle null response in user profile

When the API returns null for user profile, the app was crashing.
Now it shows a proper error message.

Fixes #456"

Commit Message Best Practices

Keep the title under 50 characters.
Limit body lines to 72 characters.
Use present tense ("add" instead of "added").
Do not capitalize the first letter.
Do not end the title with a period.
Reference issue numbers (e.g., Fixes #123).

Automated Validation

Use husky + commitlint for automatic commit message validation:

// package.json
{
  "husky": {
    "hooks": {
      "commit-msg": "commitlint -E HUSKY_GIT_PARAMS"
    }
  }
}

Tools and Configurations

ESLint Configuration Example

// .eslintrc.js
module.exports = {
  extends: ['airbnb', 'prettier'],
  plugins: ['prettier'],
  rules: {
    'prettier/prettier': 'error',
    'react/jsx-filename-extension': [1, { extensions: ['.js', '.jsx'] }],
    'import/prefer-default-export': 'off'
  }
};

Prettier Configuration Example

// .prettierrc
{
  "printWidth": 80,
  "tabWidth": 2,
  "useTabs": false,
  "semi": true,
  "singleQuote": true,
  "trailingComma": "es5",
  "bracketSpacing": true,
  "jsxBracketSameLine": false,
  "arrowParens": "avoid"
}

Git Hook Configuration

# Install husky
npm install husky --save-dev

# Install commitlint
npm install @commitlint/{config-conventional,cli} --save-dev

# Create commitlint config file
echo "module.exports = {extends: ['@commitlint/config-conventional']}" > commitlint.config.js

Common Issues and Solutions

Handling Code Conflicts

When multiple people modify the same file:

Frequently pull the latest code.
Use git rebase instead of git merge.
Make small, incremental commits to avoid large-scale changes.

# Conflict resolution example
git fetch origin
git rebase origin/develop
# After resolving conflicts
git add .
git rebase --continue

Modifying Commit Messages

If a commit message does not meet standards:

# Amend the last commit
git commit --amend

# Modify historical commits (use with caution)
git rebase -i HEAD~3

Large File Commits

Avoid committing large files to the repository:

Use .gitignore to exclude build artifacts.
For already committed large files, use git filter-branch or BFG to clean up.

# Example of removing large files from history
git filter-branch --force --index-filter \
  "git rm --cached --ignore-unmatch path/to/large/file" \
  --prune-empty --tag-name-filter cat -- --all

Continuous Integration and Automation

CI/CD Integration

Add standards checks to the CI pipeline:

# .github/workflows/ci.yml example
name: CI
on: [push, pull_request]
jobs:
  lint:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - run: npm install
      - run: npm run lint
      - run: npm run test

Automated Version Releases

Use semantic-release to automate versioning and changelog generation:

// package.json
{
  "release": {
    "branches": ["main"],
    "plugins": [
      "@semantic-release/commit-analyzer",
      "@semantic-release/release-notes-generator",
      "@semantic-release/changelog",
      "@semantic-release/npm",
      "@semantic-release/git",
      "@semantic-release/github"
    ]
  }
}

Team Collaboration Tools

Project Management

Recommended tools:

Jira: Comprehensive project management.
Trello: Lightweight Kanban management.
GitHub Projects: Integrated with code repositories.

Code Collaboration Platforms

GitHub: The most popular code hosting platform.
GitLab: Built-in CI/CD functionality.
Bitbucket: Suitable for small teams.

Communication Tools

Slack: Team instant messaging.
Discord: Community communication.
Lark/DingTalk: Commonly used by domestic teams.

Code Quality Assurance

Unit Testing Standards

Test files should have the same name as the tested file, with a .test suffix:

src/
  components/
    Button/
      Button.js
      Button.test.js

Testing example:

// Button.test.js
import React from 'react';
import { render, screen } from '@testing-library/react';
import Button from './Button';

test('renders button with text', () => {
  render(<Button>Click me</Button>);
  expect(screen.getByText('Click me')).toBeInTheDocument();
});

E2E Testing

Use Cypress for end-to-end testing:

// cypress/integration/login.spec.js
describe('Login', () => {
  it('should login with valid credentials', () => {
    cy.visit('/login');
    cy.get('#email').type('user@example.com');
    cy.get('#password').type('password123');
    cy.get('button[type="submit"]').click();
    cy.url().should('include', '/dashboard');
  });
});

Performance Optimization Collaboration

Performance Checklist

Teams should share performance optimization knowledge:

Image compression (use WebP format).
Code splitting (React.lazy, dynamic import).
Avoid unnecessary re-renders.
Use memoization.

// Code splitting example
const LazyComponent = React.lazy(() => import('./LazyComponent'));

function MyComponent() {
  return (
    <Suspense fallback={<div>Loading...</div>}>
      <LazyComponent />
    </Suspense>
  );
}

Performance Monitoring

Integrate monitoring tools:

Lighthouse CI.
Web Vitals.
Sentry.

// Monitor Web Vitals
import { getCLS, getFID, getLCP } from 'web-vitals';

getCLS(console.log);
getFID(console.log);
getLCP(console.log);
