    Organize Your Grunt config

    This plugin requires Grunt ~0.4.0

    If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

    $ npm install grunto --save-dev

    Expanding the capabilities of Grunt. Maintenance of large config fles.

    You can continue as you used to adding syntactical sugar to boring unmainteined Grunt configs.

    1. You can cut grunt build projects into litte pieces simplifying the maintenance.
    2. You can add runtime generation of task configs. That can help in some complex cases (e.g. with r.js).
    3. You can also use utilities to create grunt tasks.

    History

    We're using grunt for more than a year. It's a superb file handling, build and deployment tool. It's done a lot work for us so far and we're happy with it. But at some point we're facing issues with maintenance of task configs. We end up with 35 tasks (including custom ones), 180 subtasks, 20 aliases to maintain everything. Gruntfle.js s as fat as 2500 liines (not including custom tasks). We try arranging the task configs based on task names e.g. moving "copy" or "clean" to separate files. That helps a bit but is still a make-do. It doesn't solve the maintenance of the lines. Worse, it complicates search.

    So we come up with purpose-based arrangement - the one employed in usual programming.

    1. cut config into files and put them in the "grunt" folder in the project root.
    2. split tasks based on their purpose The final structure looks something like

    Here you can see which parts of the system work with Grunt, which are then to be minified, deployed and processed. It's easy to choose place for your new system components.

    To start the task grunt/client/compile/templates you should only execute:

    $ grunt client/compile/template

    To start compiling all the the client's components, minify and prepare everything for deployment:

    $ grunt client/compile client/minify

    First all tasks from grunt/client/compile/default.js and then all tasks from grunt/client/minify/default.js will be fired. Predictable, you must admit.

    We aggreed that all tasks named **/default.js, fire all tasks in it's folder in the right order. We don't insist on that so it's up to your team but it worked fine for us.

    Getting Started

    Gruntfile.js

    var grunto = require('./lib/grunto');
    module.exports = grunto(function(grunt) {
        // put your code here
    });

    Init configs

    Usually used to init general config for all similar task (with eq names, such as copy or clean)

     
    // first case (default for grunt)
    module.exports = grunto(function (grunt) {
        grunt.initConfig({
            clean: {
                targetName: [
                    'tmp/dir/for/clean'
                ]
            }
        });
    });
     
    // second case
    module.exports = grunto(function (grunt) {
        return {
            clean: {
                targetName: [
                    'tmp/dir/for/clean'
                ]
            }
        };
    });
     
    // third case
    module.exports = grunto(function(grunt) {
        this.config({
            clean: {
                targetName: [
                    'tmp/dir/for/clean'
                ]
            }
        });
    });

    You should not use multiple config inits. It usually adds dissonance to configuration.

    Advanced Usage

    You have grunt modules fs

    to run this task

    $ grunt build/styles

    Sum up

    You can create complex setups avoiding code duplication and config confusion. This approach helps you to arrange appropriate structure for building complex projects that is clear, predictable and simple.
