Clean task

Generating and processing files is great, but there may come a time when you or your teammates need to simply clear out the files that you have processed and start anew.

To do so, we are going to create another task that will clean out any processed files from our dist directory. To do this, we are going to use a node module called del, which will allow us to target multiple files and use globs in our file paths.

Installing the del module

Install the del module using npm and then save it to your list of development dependencies with the --save-dev flag:

npm install del --save-dev

The following screenshot shows the installation of the del module:

Including the del module

Once the module has been installed, you must add it to your list of required modules at the top of your gulpfile:

    // Load Node Modules/Plugins
    var gulp = require('gulp');
    var concat = require('gulp-concat');
    var uglify = require('gulp-uglify');
    var jshint = require('gulp-jshint');
    var imagemin ...
