Trying to create one css file for one sass file (and also using multiple sass files in one css file) with Grunt

I have a project that uses the default setting of using multiple sass files and partial files that are compiled into one global css file.

Now I need the functionality to also have single sass files for single css files (these are components / widgets).

So, in my final markup, the widget will have something like:

<link rel="stylesheet" href="css/main.css"/>
<link rel="stylesheet" href="css/widgets/widget-name.css"/>

I've tried several options in my grunt file. The current setup looks like this:

 sass: {
        dist: {
            options: {
                style: 'compressed'
            },
            files: {
                 "Webcontent/css/site.css": "WebContent/source/sass/site.scss"
            }
        } 
    },
    watch: {
        src: {
            files: ['WebContent/source/sass/*.scss'],
            tasks: ['sass'],
        }
    }

I've tried the following:

sass: {
        dist: {
            options: {
                style: 'compressed'
            },
            files: {
                 "Webcontent/css/site.css": "WebContent/source/sass/site.scss",
                 "Webcontent/css/widgets/*.css": "WebContent/source/sass/widgets/*.scss",
            }
        } 
    },

As well as:

sass: {
        dist: {
            options: {
                style: 'compressed'
            },

            files: [
                {src: 'WebContent/source/sass/site.scss', dest: 'Webcontent/css/site.css'},
                {src: 'WebContent/source/sass/widgets/*.scss', dest: 'Webcontent/css/widgets/*.css' },
              ],
        } 
    },
    watch: {
        src: {
            files: ['WebContent/source/sass/*.scss', 'WebContent/source/sass/widgets/*.scss'],
            tasks: ['sass'],
        }
    }

I keep getting the error: Warning: Warning: Unable to write "Webcontent/css/widgets/*.css" file (Error code: ENOENT ).

Surely I don't need to specify the target css file?

Any help is greatly appreciated.

To compile all files in a folder, you can do this:



sass: {
    dist: {
        files: [
          {
            expand: true, // Recursive
            cwd: "WebContent/source/sass", // The startup directory
            src: ["**/*.scss"], // Source files
            dest: "Webcontent/css", // Destination
            ext: ".css" // File extension 
          }
        ]
    }
}

Based on your first solution and http://ryanchristiani.com/getting-started-with-grunt-and-sass/ , your "watched" files should more likely look like this:

(not sure if it really matters, but better try)

watch: {
  src: {
    files: 'WebContent/source/sass/*.scss',
    tasks: ['sass'],
  }
}

Otherwise it is usually easier to create your Gruntfile.js like this:

(only main.scss is compiled and all other files @import

into this main.scss)



watch: {
  sass: {
    files: './assets/css/sass/*.scss',
    tasks: ['sass', 'cssmin']
  }
},
sass: require( './assets/custom_modules/sass.js' ).task,
cssmin: require( './assets/custom_modules/cssmin.js' ).task

Then in sass.js

exports.task = {
  dist: {
    options: {
      style: 'expanded',
      lineNumbers: true,
      sourcemap: 'none'
    },
    files: [{
      expand: true,
      cwd: 'assets/css/sass/',
      src: [ 'main.scss' ],
      dest: 'assets/css/',
      ext: '.css'
    }]
  }
};

Hope this can help.

Good luck '
