grunt-scss-image-helpers

Grunt tasks to replace Compass image helpers. It is recommended to run this task with watch task on image folder only.

This fork allows you to set prefixFunctions string in the options.

Helpers

All helpers have one argument: image name. Name is created relatively to the imageRoot option. If we want to use an image in subfolder, we need to enter a path incl. folder name.

Example: image-url('foo.png'), image-url('subfolder/foo.png')

image-width()

Returns width of specified image in pixels (for example 30px).

image-height()

Returns height of specified image in pixels (for example 30px).

image-url()

Returns path to specified image including url().

Example: background-image: image-url('foo.bar') is compiled to background-image: url('foo.bar').

When relativePath is set to ../img/, helper will return url('../img/foo.bar').

When antiCache is set to true, helper will return path with timestamp: url('foo.12345678.bar) or url('../img/foo.12345678.bar').

inline-image()

Returns image as data url.

Example: inline-image('foo.png') becomes url('data:image/png;base64,...').

Options

imageRoot

Type: String
Default: ''

Path to image folder. All image names are created relatively to this folder.

prefix

Type: String
Default: grunt-images

Prefix for SCSS variables. These variables are created: $grunt-images-names, $grunt-images-widths, $grunt-images-heights, $grunt-images-base64 and $grunt-images-relative-path.

prefixFunctions

Type: String Default: ``

Prefix for function names. These functions are created: {prefixFunctions}image-width, {prefixFunctions}image-height, {prefixFunctions}image-url and {prefixFunctions}inline-image.

antiCache

Type: Boolean
Default: false

If set to true, task generates file names with timestamps to invalidate browser cache.

relativePath

Type: String
Default: ''

All image paths in css are prefixed with this path. For example path ../img/ and image foo.png become ../img/foo.png.

size

Type: Integer
Default: 10240

Maximum file size for base64 encoding. Images bigger than that won't be encoded.

Example config

grunt.initConfig({
    scss_images: {
        dist: {
            options: {
                imageRoot: 'assets/img/',
                prefix: 'grunt-images',
                antiCache: true,
                relativePath: '../img/',
                size: 4096
            },
            files: {
                'assets/scss/_images.scss': ['assets/img/*.png']
            }
        }
    }
});
 
grunt.loadNpmTasks('grunt-scss-image-helpers');
grunt.registerTask('default', ['scss_images']);
