In this recipe, we'll make use of the contrib-imagemin (0.9.4) plugin to decrease the size of images by compressing them as much as possible without compromising on their quality. This plugin also provides a plugin framework of its own, which is discussed at the end of this recipe.
In this example, we'll work with the basic project structure we created in the Installing Grunt on a project recipe in Chapter 1, Getting Started with Grunt. Be sure to refer to it if you are not yet familiar with its contents.
The following steps take us through configuring a task that will compress an image for our project.
We'll start by installing the package that contains the
contrib-imageminplugin as per the instructions provided in the Installing a plugin recipe in Chapter 1, Getting Started with Grunt.Next, we can ensure that we have an image called
image.jpgin thesrcdirectory on which we'd like to perform optimizations.
