coffee.config.cjs

/** @type {import('@milkee/d').Config} */

module.exports = {
  // The entry point for compilation.
  // This can be a single file or a directory (e.g., 'src/' or 'src/app.coffee').
  entry: 'src',
  // The output for the compiled JavaScript files.
  // If 'options.join' is true, this should be a single file path (e.g., 'dist/app.js').
  // If 'options.join' is false, this should be a directory (e.g., 'dist').
  output: 'dist',
  // (Optional) Additional options for the CoffeeScript compiler.
  // See `coffee --help` for all available options.
  // Web: https://coffeescript.org/annotated-source/command.html
  options: {
    // The following options are supported:
    // bare: false,
    // join: false,
    // map: false,
    // inlineMap: false,
    // noHeader: false,
    // transpile: false,
    // literate: false,
    // watch: false,
  },
  // (Optional) Additional options/plugins for the Milkee builder.
  milkee: {
    options: {
      // Ignore update notifications.
      // ignoreUpdate: false,
      // Before compiling, reset the directory.
      // refresh: false,
      // Before compiling, confirm "Do you want to Continue?"
      // confirm: false,
      // After compiling, copy non-coffee files from entry to output directory. (Only works when options.join is false)
      // copy: false,
    },
    plugins: []
  },
};

options (CoffeeScript Compiler Options)

These options are passed directly to the coffee compiler.

Option	Type	Default	Description
bare	boolean	false	compile without a top-level function wrapper
join	boolean	false	concatenate the source CoffeeScript before compiling
map	boolean	false	generate source map and save as .js.map files
inlineMap	boolean	false	generate source map and include it directly in output
noHeader	boolean	false	suppress the "Generated by" header
transpile	boolean	false	pipe generated JavaScript through Babel
literate	boolean	false	treat stdio as literate style coffeescript
watch	boolean	false	watch scripts for changes and rerun commands

CoffeeScript - command.coffee

milkee.options (Milkee Specific Options)

These options control Milkee's behavior.

Option	Type	Default	Description
ignoreUpdate	boolean	false	Ignore update notifications.
refresh	boolean	false	Before compiling, reset the output directory.
confirm	boolean	false	Before compiling, prompt "Do you want to Continue?".
copy	boolean	false	After compiling, copy non-coffee files from entry to output directory. (Only works when options.join is false)

milkee.plugins (Milkee Specific Plugins)

You can extend Milkee's functionality by using plugins. Plugins are simple functions that run after each successful compilation, giving you access to the compiled files and configuration.

Example:

const myPlugin = require('./plugins/my-plugin.js');

module.exports = {
  // ...
  milkee: {
    plugins: [
      // This call returns the PluginExecutor
      myPlugin({ option: 'value' }),
      // ...
    ]
  }
}

Compile

Milkee will automatically read coffee.config.cjs, assemble the command from your options, and start compilation!

# global
milkee

# or local
npx milkee
