Formatting Standards

Tools

This repository uses:

• ESLint for code quality (extends GTS)
• Prettier for formatting (extends GTS)
• GTS (Google TypeScript Style) for TypeScript style

Configuration Files

• .eslintrc.json - ESLint configuration (extends GTS)
• .prettierrc.js - Prettier configuration (extends GTS)
• .eslintignore - Files to ignore for linting
• .prettierignore - Files to ignore for formatting

Formatting Rules

Based on GTS and project configuration:

• Indentation: 4 spaces (not tabs)
• Line Width: 160 characters
• Import Spacing: Spaces around braces: { Item } not {Item}
• Function Signatures: Multi-line when they exceed print width
• Arrow Functions: Parentheses around single parameters: (x) => not x =>
• Quotes: Single quotes (from GTS)
• Semicolons: Required (from GTS)
• Trailing Commas: ES5 style (from GTS)

Running Formatting

# Format all files
npm run format

# Check formatting without writing
npm run format:check

# Format and fix linting issues
npm run format:fix

VS Code Integration

Format on save is configured in .vscode/settings.json:

• Prettier is the default formatter
• ESLint auto-fix on save
• Format on save enabled for TypeScript, JavaScript, JSON

Before Committing

Always run:

npm run format:fix

This ensures:

• Code is formatted according to GTS/Prettier rules
• Linting issues are automatically fixed
• Consistent code style across the repository
