milkee-plugin-prettier

A Milkee plugin for working with Prettier for CoffeeScript without version conflicts.

Tip

Uses Optimized-Prettier (by helixbass) and prettier-plugin-coffeescript (by helixbass) to format CoffeeScript files.

Features

• Recursively finds .coffee files in the build entry directory and formats them with Prettier.
• Supports a prettierrc (object or a path to a config file) and .prettierignore to exclude files.
• Automatically resolves config via prettier.resolveConfig() or package.json#prettier when prettierrc is not provided.

Usage

As a Milkee Plugin (coffee.config.cjs)

const prettierPlugin = require('milkee-plugin-prettier');

module.exports = {
  entry: 'src',
  output: 'dist',
  milkee: {
    plugins: [
      // Pass options (optional)
      prettierPlugin({
        prettierrc: { tabWidth: 2 },        // or a path to a config file
        prettierignore: '.prettierignore'   // optional, resolved from cwd
      })
    ]
  }
};

As a CLI Tool

You can also use this package as a standalone CLI tool to format CoffeeScript files:

# Format files in the current directory
npx cprettier

# Format files in a specific directory
npx cprettier src

The CLI will:

• Recursively find all .coffee files in the target directory
• Respect .prettierignore and prettier config files (.prettierrc, prettier.config.js, or package.json#prettier)
• Format files in place

Notes

• .prettierignore is resolved relative to process.cwd() by default. You can pass an absolute or relative path via the prettierignore option.
• When config.options.join is used and a single entry file is emitted, the plugin will use the directory of the entry file as the search root for .coffee files.
