The src folder sometimes called app contains the source code of the library as you author it. The dist folder sometimes called build contains the distribution, a minified version of the source code. A minified file is one where all unnecessary characters, such as spaces, new lines, comments are removed, without affecting the functionality of the source code. Minified source code is especially useful for users of the project because it reduces the amount of data that needs to be transferred. Finally, the test folder contains the code to test the project. This set up will be used in the next sections when creating the Gruntfile configuration.
While developing the library and releasing new versions there are a few tasks that you need to perform on a regular basis. For example, you might want to ensure that the code you write adheres to best practices, or that the code you've written doesn't result in unexpected behaviors. To do that, you can employ a tool called JSHint.
Grunt has an official plugin for it called grunt-contrib-jshint which we'll adopt in this example. In particular, you might want to ensure that as you modify your code, you don't break any rules or best practices. So, a good strategy is to check the code at every change you perform. To do that, we'll cover a Grunt plugin called grunt-contrib-watch. The latter runs predefined tasks, such as grunt-contrib-jshint , whenever files are added, changed, or deleted. Checking that your source code follows best practices is not enough to guarantee that it's stable and doesn't contain bugs.
To create a robust project, you need to test it. There are several libraries you can adopt such as QUnit or Jasmine. In this guide, we describe how to configure QUnit, and specifically grunt-contrib-qunit , to test your code. When it comes to distributing your work, you want to offer a version as small in size as possible. To create a minified version you need a Grunt plugin like grunt-contrib-uglify. Moreover, unless the project you're developing is very small, chances are that you've split the code in multiple files.

While this is a good practice for the developer, you want users to include only one file. So, before minifying the code, you should concatenate the source files to create a single one. To achieve this goal you need a Grunt plugin like grunt-contrib-concat.

If you're curious about what the final result looks like, the entire Gruntfile can be found at the bottom of this page. Next, we can store the project settings from the package. This allows us to refer to the values of properties within our package. Now we can define a configuration for each of the tasks we mentioned.
The configuration object for a plugin lives as a property on the configuration object, that often shares the same name as its plugin. The configuration for grunt-contrib-concat goes in the configuration object under the concat key as shown below:. Note how in the snippet above we refer to the name property that's in the JSON file.

We access it by using pkg. Grunt has a simple template engine to output the values of properties in the configuration object. The first thing you want to add is the Grunt module. Then add the options for cssmin:. This is because load-grunt-configs uses the file's name to recognize which task is being run. If you're using grunt-postcss.
This is how we're adding the module design concept to our grunt tasks.
Each task will have its own file containing the task's options. This makes to easy to add new tasks, and for multiple developers to makes changes without the worries of accidentally messing up another task in a enormous Gruntfile. Now when you run your grunt task. This was a basic example of this technique. The load-grunt-tasks and load-grunt-configs packages have more options available that can give you even more control of your Grunt tasks.
I hope this helps you get your Gruntfile under control and add more flexibility to your projects using Grunt. NPM scripts? Do we hate Gulp now? What are your main gripes with Grunt? I still use it also.
Running Grunt tasks from the tasks tree
I always keep an eye out though. Alex — The reason I personally switched from Grunt to Gulp was that I felt that Gulp was significantly faster at running tasks. For me, switching from grunt-contrib-sass which uses Ruby Sass to grunt-sass which uses LibSass helped a lot. Same here. I found grunt-contrib-sass to be extremely slow. I use Grunt and Gulp together , because Grunt has way more packages available than Gulp does. You get the best of both worlds then.

To accomplish this, we're going to install two Grunt packages. Then add the options for cssmin: module. Permalink to comment August 4, Does anyone still use grunt in non legacy projects?
