How does Prettier work in team collaboration and what are the best practices?

Prettier Application in Team Collaboration

Prettier plays an important role in team collaboration. By enforcing unified code style, it can effectively reduce format disputes during code reviews and improve team development efficiency.

Value in Team Collaboration

1. Eliminate Style Debates

• Unify code format, avoiding style preference debates among team members
• Reduce format-related comments during code reviews
• Let developers focus on code logic rather than format

2. Improve Code Readability

• Unified format makes code easier to read and understand
• New members can adapt to project code style faster
• Reduce code maintenance costs

3. Automated Processes

• Automatically format code through Git hooks
• Enforce code format checking in CI/CD
• Reduce manual formatting workload

Team Configuration Strategy

1. Unified Configuration File

json
// .prettierrc - Team unified configuration
{
  "semi": true,
  "singleQuote": true,
  "tabWidth": 2,
  "trailingComma": "es5",
  "printWidth": 80,
  "bracketSpacing": true
}

2. Configuration File Version Control

• Commit .prettierrc and .prettierignore to version control
• Ensure all team members use the same configuration
• Document Prettier configuration in README

3. Unified Editor Configuration

json
// .vscode/settings.json - VS Code team configuration
{
  "editor.defaultFormatter": "esbenp.prettier-vscode",
  "editor.formatOnSave": true,
  "editor.codeActionsOnSave": {
    "source.fixAll.eslint": true
  }
}

Workflow Integration

1. Git Hooks Integration

bash
# Use Husky and lint-staged
npm install --save-dev husky lint-staged prettier

# Configure pre-commit hook
npx husky add .husky/pre-commit "npx lint-staged"

2. CI/CD Checking

yaml
# GitHub Actions
- name: Check code format
  run: npx prettier --check "**/*.{js,jsx,ts,tsx,json,css,md}"

3. Pull Request Template Remind developers to format code in PR template:

markdown
## Pre-submission Checklist
- [ ] Code has been formatted with Prettier
- [ ] Run `npm run format:check` to confirm format is correct

Team Best Practices

1. New Member Onboarding

• Document Prettier usage in onboarding materials
• Provide editor configuration guide
• Install necessary dependencies and plugins

2. Code Review Process

• Use Prettier auto-formatting to reduce format discussions in reviews
• Enforce format checking in CI,不合格的 PR cannot merge
• Provide clear formatting error messages

3. Regular Updates

• Regularly update Prettier version
• Evaluate new configuration options
• Document configuration change history

4. Documentation Maintenance

• Document Prettier configuration in README
• Provide FAQ
• Record team-agreed format standards

Solving Common Problems

1. Configuration Inconsistency

• Use unified configuration files
• Regularly sync team member configurations
• Enforce project configuration in CI

2. Performance Issues

• Use lint-staged to only format staged files
• Configure .prettierignore to ignore unnecessary files
• Use caching mechanism to improve performance

3. Legacy Code Formatting

• Gradually format legacy code to avoid massive changes
• Use --write option for batch formatting
• Perform formatting in separate PRs

With proper configuration and usage, Prettier can significantly improve team collaboration efficiency, allowing the team to focus on code quality rather than format issues.
