After some great interest in why I ditched Sublime Text 2 for the day to fully code inside Google Chrome, here’s the promised screencast on how to do it yourself.

I’m using Sass/SCSS (.scss) and JavaScript, both of which compile, concat + minify and livereload the browser, ice cool. In the video I’m using Grunt and Chrome’s Workspaces to manage all of this, enjoy!

Setting up Grunt

Workspaces don’t require Grunt at all, it just saves me using software and refreshing the page myself, but Grunt is very flexible and reliable and I really advocate using it. It’s a fairly simple learning curve if you’re used to structuring JavaScript/JSON. If not, it’s a very readable format that you’ll pick up quickly anyway. Workspaces is very easy to setup, but here’s how to do the Grunt bit.

First you’ll need to setup Grunt locally, which requires Node.js so make sure you’ve got that installed first. I love using SourceTree by Atlassian which has a neat ‘Terminal’ button that auto-locates your project so you don’t have to change directory yourself (that’s if you’re using Git, anyway, if not slap your wrists).

Now, you’ll want to do as I did in the video, and locate your project by using ‘cd’ (change directory) on the command line. Next, we need to install all project dependencies (internet connection required), which uses Node Package Manager (npm) to fetch. Once your Terminal is pointing at your project folder with your package.json and Gruntfile.js in, run the following:

npm install

This will then loop through your package.json and install all the necessary stuff. If your permissions are uptight, you’ll need to run the following instead (which you’ll need to authenticate with a password):

sudo npm install

Once that’s successfully downloaded all the dependency components, just run Grunt:


You’ll then hopefully see the following:

Running "sass:dist" (sass) task

Running "uglify:dist" (uglify) task
File "dist/js/scripts.min.js" created.

Running "connect:livereload" (connect) task
Started connect web server on localhost:9000.

Running "open:server" (open) task

Running "watch" task

That’s good news, you’re good to go. Happy coding.


One thing I didn’t mention inside the video was Sass/SCSS sourcemapping (though sourcemapping is standalone tech and not limited to Sass itself). It essentially allows you to Inspect Element, and instead of seeing style.min.css inside the developer tools, you’ll actually going to drill down into the non-compiled Sass and you’ll see something like __inputs.scss_! This is coming in the latest version of Sass but is available now on prerelease:

gem install sass --pre
