So you want to develop your own website which is modern, easy to use, attractive to users, and works well across all browsers and platforms? Well, this usually requires a lot of work based on the complexity of your website. But there is an amazing tool which helps you immensely with the development and work-flow of your application: a task-based build tool called Grunt.
With Grunt, you can do almost anything. You can configure it to do specific tasks like concatenating and minifying while watching for changes in your source code.
Confused? Let me explain to you how the above mentioned tasks impact your site performance and why you should use them.
Grunt is simple and it makes almost everything automated. You surely don't want to run your concatenating and minifying processes manually by hand every time you do a tiny change in your source code. This is where Grunt comes in, it not only makes your job faster and easier, but more enjoyable too. It takes once to set up and zero effort after that.
Another benefit of Grunt is its ecosystem, which leads to its growth and the development of many new useful plugins. So why not create your own Grunt-plugin with a custom task you use often? Some of the most common tasks have already been turned into Grunt-plugins, therefore taking a look at the plugin list, choosing the one you need and configuring it is going to be enough to set up your task automation.
This tutorial assumes that you're already familiar with node.js, npm, basic Linux administrative tasks like connecting to your VPS using SSH but most importantly, that you already have a basic website project using a web application framework like Express.
If you're unfamiliar with node.js or if you haven't installed it yet, please refer to the node.js section on the Articles & Tutorials page above to find installation instructions for your operating system.
We also have many great articles on our Help & Community page about Linux Basics.
Let's get started by installing Grunt's command line interface (CLI) globally by issuing the following command:
npm install -g grunt-cli
You might have to use
sudo npm install -g grunt-cli (if
you are on Linux, OSX, BSD, etc.) or run your command as Administrator
on a Windows-based system.
Now we have to change into the directory of your web-project using the
cd /path/to/your/project/ command.
Install Grunt and our required Grunt-plugin dependencies in your project directory using this command:
npm install grunt grunt-contrib-concat grunt-contrib-uglify grunt-contrib-cssmin grunt-contrib-watch --save-dev
Create a new Grunt configuration file called
Gruntfile.js at the
root level of your project and add the following sample configuration:
Execute our Grunt task by simply issuing
grunt in your terminal and it should display an output similar to the following:
Running "concat:js" (concat) task File "dist/js/application-name.js" created. Running "concat:css" (concat) task File "dist/css/application-name.css" created. Running "uglify:dist" (uglify) task File "dist/js/application-name.min.js" created. Running "cssmin:add_banner" (cssmin) task File dist/css/application-name.min.css created. Running "watch" task Waiting...
Grunt will now watch for any changes in your source code and concatenate/minify your source code whenever you modify it.
