@import.js

A node.js module that combines JavaScript files through the use of an @import directive.

Requirements

Introduction

@import.js is used to automate the concatenation of JavaScript files through the use of a custom import directive comment. Only two types of paths are able to be passed to the import directive, a path to a directory or a path to a file; it does not support wildcards and will only recognize files that end in the .js extension. Directories will be searched recursively unless the shallow_import directive is used.

@import.js will not import a file more than once. If an imported file references another file that has already been imported @import.js will ignore it.

The file names MUST be encased in double quotes ("), single quotes (') will not be recognized.

You may pass multiple files to a single directive, all files must be encased in double quotes and separated by commas.

You may use either single-line (//) or multi-line (/**/) comments.

The file referenced by the @import.js directive will be placed at the tab position of the first character of the comment.

Directive Examples:

Given the following directory structure:

* main.js
* lib/
    * attributes.js
    * backbone/
        * backbone.js
    * jQuery.js
* views/    
    * shared/
        * _login.js
    * view1.js

The following will import the files in this order: main.js

// @import("main.js")

The following will import the files in this order: lib/attributes.js, lib/backbone/backbone.js, lib/jQuery.js

/* @import("lib") */

The following will import the files in this order: lib/jQuery.js, lib/attributes.js, lib/backbone/backbone.js

// @import("lib/jQuery.js", "lib")

The following will import the files in this order: views/view1.js

// @shallow_import("views")

Library Usage

var atImport = require('at-import');

atImport({
  input: 'main.js',
  output: 'script.js',
  replacements = {
    '@@VERSION@@': '1.0.0'
  }
});

Arguments

* `options`
    * `input` = The input JavaScript file
    * `output` = The output JavaScript file
    * `replacements` = An object containing a map of text replacements
* `callback`

Demo

The application within /demo contains a small display of how you could use @import.js to combine JS files.

cd demo
