Generating source maps for LESS


In this recipe, we'll make use of the contrib-less (0.11.4) plugin to generate source maps when compiling our LESS style sheets to CSS.

Getting ready

In this example, we'll work with the basic project structure that we created in the Compiling LESS to CSS recipe of this chapter. Be sure to refer to it if you are not yet familiar with its contents.

How to do it...

The following steps will take us through compiling our LESS style sheet to a CSS file, which contains both our source map and the source style sheet:

  1. First, we'll indicate that we'd like to generate a source map by setting the sourceMap option to true in our less task's configuration:

    less: {
      styles: {
        options: {
          sourceMap: true
        },
        src: 'styles.less',
        dest: 'styles.css'
      }
    }
  2. Next, we'll indicate that we'd like to include the source of the generated CSS in the resulting file by setting the outputSourceFiles option to true in task's configuration:

    less: {
      styles: {
        options: {...
