Tag: grunt

This year I’ve started working with some new tools, two of them are Grunt and Sass. Grunt is a commandline JavaScript Task Runner, and Sass is a Css preprocessor allowing you to write more powerful css, with the use of variables, mixins/functions and nesting!

Off we go !

First of all you’ll need to install a few things. Ruby to get Sass, and NodeJs to get npm, so we can work with Grunt.

Grunt

Step one: installing Grunt. If you have NodeJs installed properly you simply run: npm install -g grunt-cli

This will install Grunt globally. So you can use it wherever you want.

Now we need to create the “package.json” file there are several ways to do this. But I prefer to create a new file and input this.

{
  "name": "Project Name",
  "version": "0.0.1",
  "devDependencies": {
     //installed packages 
  }
}

And then save it as “package.json” in the root of my project.

After that we need to install our Dependencies. This can be done by running the following command: npm install <package> --save-dev

I want to use Grunt to compile my Sass when I save my project. To do this I need to install 2 dependencies.

grunt-contrib-sass: It is used to actually compile your scss files to css.

grunt-contrib-watch: It watches our folders for file changes.

Example

npm install grunt-contrib-sass --save-dev

Now my “package.json” looks like this:

"devDependencies": {
    "grunt": "~0.4.1",
    "grunt-contrib-sass": "~0.3.0",
    "grunt-contrib-watch": "~0.4.4"
}

Next is our “Gruntfile.js”. This file contains the tasks that grunt needs to do for you.

This is how my Gruntfile looks like:

module.exports = function(grunt) {
    grunt.initConfig({
        pkg: grunt.file.readJSON('package.json'),
        sass: {
            dist: {
                files: {
                    'style/style.css' : 'sass/style.scss'
                }
            }
        },
        watch: {
            css: {
            files: '**/*.scss',
            tasks: ['sass']
            }
        }
    });
    grunt.loadNpmTasks('grunt-contrib-sass');
    grunt.loadNpmTasks('grunt-contrib-watch');
    grunt.registerTask('default',['watch']);
}

This file starts with a wrapper function and we pass in grunt so that we can access it..

Adding tasks with :

grunt.loadNpmTasks('*Name of the task*')

Register Tasks with :

grunt.registerTask('default',['*tasks to run*']);

the 'default' task is what gets running when you type grunt in the commandline.

The end !

When working on your project, just run the grunt command in your commandline in your project folder.

Hit ctrl+c to quit grunt when you’re done.
