CoffeeScript Compiler

Introduction

This is a node module which allows you to compile CoffeeScript code (strings of code or files containing code) to JavaScript from JavaScript. Output is provided as a string and can optionally be written out to a file.

Usage

You can install this package via npm install coffeescript-compiler. Please note that this package does NOT define any version of coffee-script as a dependency for any reason other than testing. You must either have the coffee command available in your path or have the complete path to access the coffee command.

All examples assume that you have included this module and created a new Compiler as follows:

var Compiler = require('coffeescript-compiler');
var cc = new Compiler();

Assuming you have coffee on your path, compiling a string of CoffeeScript (in this example, a = 5) is simple:

cc.compile('a = 5', function (status, output) {
    if (status === 0) {
        // JavaScript available as a string in the `output` variable
    }
});

You can get a bare compilation (no wrapper function) by passing in a configuration object as the second argument to compile(...):

cc.compile('a = 5', {bare: true}, function (status, output) {
    if (status === 0) {
        // Bare JavaScript available as a string in the `output` variable
    }
});

The configuration object can contain the following options:

  • asFileName: If set to true the first argument passed to compile is treated as a file name rather than an input string. If this is set and an error is encountered while reading the error will be thrown.
  • bare: Compiles input to bare JavaScript if set to true.
  • writeFile: A string containing a filename to write JavaScript output to. If this is set and an error is encountered while writing the error will be thrown.
