@crewspace/prettier-config

Shareable Prettier config for Crewspace projects. Enforces consistent formatting across agent orchestration codebases — single quotes, trailing commas, 2-space indentation, and 100-char line width.

Installation

npm install --save-dev @crewspace/prettier-config prettier

Quick Start

Reference the package directly in your package.json:

{
  "prettier": "@crewspace/prettier-config"
}

Or create a .prettierrc.mjs file:

import config from '@crewspace/prettier-config';

export default config;

Customization

Use createConfig() to override specific options while keeping Crewspace defaults:

// .prettierrc.mjs
import { createConfig } from '@crewspace/prettier-config';

export default createConfig({
  printWidth: 120,
  tabWidth: 4,
});

Options

| Option | Type | Default | Description | |--------|------|---------|-------------| | semi | boolean | true | Print semicolons at ends of statements | | singleQuote | boolean | true | Use single quotes instead of double | | trailingComma | "all" \| "es5" \| "none" | "all" | Trailing commas in multi-line structures | | printWidth | number | 100 | Line width before wrapping | | tabWidth | number | 2 | Spaces per indentation level | | useTabs | boolean | false | Indent with tabs | | bracketSpacing | boolean | true | Spaces in object literal braces | | arrowParens | "always" \| "avoid" | "always" | Parens around sole arrow function param | | endOfLine | "lf" \| "crlf" \| "cr" \| "auto" | "lf" | Line ending style | | overrides | Partial<Options> | — | Additional Prettier options (for plugins etc.) |

Ignore Patterns

The package also exports recommended ignore patterns:

import { DEFAULT_IGNORE_PATTERNS } from '@crewspace/prettier-config';

// ['dist', 'node_modules', 'coverage', 'package-lock.json', '*.md']
console.log(DEFAULT_IGNORE_PATTERNS);

Use these in your .prettierignore file or pass to Prettier's CLI.

What's Configured

The Crewspace Prettier config enforces:

• Single quotes — consistent with TypeScript ecosystem conventions
• Trailing commas (all) — cleaner git diffs when adding items
• 100-char line width — readable without excessive wrapping
• 2-space indentation — TypeScript community standard
• LF line endings — cross-platform consistency in git repos
• Semicolons — explicit statement termination
• Always arrow parens — consistent (x) => x style
• Bracket spacing — { foo } not {foo}
