Convert spritesheet data into CSS or CSS pre-processor data
spritesheet-templates, formerly json2css, was built as part of spritesmith, a tool that converts images into spritesheets and CSS variables.
Install the module with: npm install spritesheet-templates

spritesheet-templates is exports the funciton templater as its module.exports.
templater(data, options)Converter for spritesheet/sprite info into spritesheet
Object - Container for data for template
Object[] - Deprecated alternative key to define data.spritesObject[] - Array of objects with coordinate data about each sprite on the spritesheet
Object - Container for sprite coordinate data
* symbolizes any index (e.g. data.sprites[0])String - Name to use for the imageNumber - Horizontal coordinate of top-left corner of imageNumber - Vertical coordinate of top-left corner of imageNumber - Horizontal length of image in pixelsNumber - Vertical length of image in pixelsObject - Information about spritesheet
Number - Horizontal length of image in pixelsNumber - Vertical length of image in pixelsString - URL to use for spritesheet
background-imagebackground-image: url({{spritesheet.image}});Object - Optional container for metadata about spritesheet and its representation
String - Prefix to use for all spritesheet variables
icons will generate $icons-width/$icons-image/etc in a SCSS templatespritesheet (e.g. $spritesheet-width, $spritesheet-image)retina templates are documented in the Retina parameters sectionObject - Optional settings
String - Deprecated alternative for spritesheet_info.nameString - Format to generate output in
css formatMixed - Options to pass through to the formatterReturns:
String - Result from specified formatterretina templates require additional parameters data.retina_sprites, data.retina_spritesheet and data.retina_groups to be passed in.
For the variables to be useful, the retina spritesheet should be a 2x scale image of the original spritesheet. Similarly, retina sprites should be positioned in the same layout and order as their normal counterparts (e.g. [{x: 0, y: 0}, {x: 20, y: 20}] should correspond to [{x: 0, y: 0}, {x: 40, y: 40}]).
Object - Same container as defined above
Object[] - Array of objects with coordinate data about each retina sprite for the retina spritesheet
data.spritesObject - Information about retina spritesheet
data.spritesheetObject - Optional container for metadata about retina_spritesheet and its representation
String - Prefix to use for all retina spritesheet variables
retina-icons will generate $retina-icons-width/$retina-icons-image/etc in a SCSS templateretina-spritesheet (e.g. $retina-spritesheet-width, $retina-spritesheet-image)Object[] - Array of objects that maps to normal and retina sprites
Object - Container for data about sprite mapping
String - Name to refer to mapping by
Number - Index to look up corresponding normal/retina sprites from data.sprites/data.retina_spritesObject - Optional container for metadata about retina_groups and its representation
String - Name to use for retina_groups variable
icon-groups will generate $icons-groups in a SCSS templateretina-groups (e.g. $retina-groups)Below are our template options for options.format.
Handlebars-based templates support inheritance via handlebars-layouts (e.g. {{#extend "css"}}). Inherited templates must copy/paste JSON front matter. An example can be found in the Examples section.
Retina templates have the same setup but are located in the Retina templates section for convenience.
cssOuput CSS variables as CSS rules.
Options:
Function - Override mapping for CSS selector
cssSelector should have signature function (sprite) { return 'selector'; }'.icon-' + sprite.namesprite with all parameters designed for templateHandlebars blocks:
css is a Handlebars based template. We allow for overriding the following sections:
{{#content "sprites-comment"}} - Comment before CSS rules{{#content "sprites"}} - CSS rulesExample:
.icon-sprite1 {
background-image: url(nested/dir/spritesheet.png);
background-position: 0px 0px;
width: 10px;
height: 20px;
}
.icon-sprite2 {
/* ... */
jsonOutput CSS variables in JSON format.
Example:
{
"sprite1": {
"x": 0,
"y": 0,
"width": 10,
"height": 20,
"total_width": 80,
"total_height": 100,
"image": "nested/dir/spritesheet.png",
"offset_x": 0,
"offset_y": 0,
"px": {
"x": "0px",
"y": "0px",
"offset_x": "0px",
"offset_y": "0px",
"height": "20px",
"width": "10px",
"total_height": "100px",
"total_width": "80px"
},
"escaped_image": "nested/dir/spritesheet.png"
},
"sprite2": {
// ...
json_arrayOutput CSS variables as an array of objects.
Example:
[
{
"name": "sprite1",
"x": 0,
"y": 0,
"width": 10,
"height": 20,
"total_width": 80,
"total_height": 100,
"image": "nested/dir/spritesheet.png",
"offset_x": 0,
"offset_y": 0,
"px": {
"x": "0px",
"y": "0px",
"offset_x": "0px",
"offset_y": "0px",
"height": "20px",
"width": "10px",
"total_height": "100px",
"total_width": "80px"
},
"escaped_image": "nested/dir/spritesheet.png"
},
{
"name": "sprite2",
// ...
json_textureOutput CSS variables as an object in format similar to that of TexturePacker. Useful for game frameworks, such as Phaser, Pixi.js, and others.
For consistency with TexturePacker, we will use the basename of a given image. spritesmith provides this via sprite.source_image. If you would like to provide a custom name, then please define sprite.frame_name:
// Input
{
sprites: [{
frame_name: 'hello', name: 'github', x: 0, y: 0, width: 10, height: 20
}]
}
// Output
{
frames: {
hello: {x: 0, y: 0, w: 10, h: 20}
}
}
If neither sprite.source_image nor spriteframe is used, then sprite.name will be used.
For integration in grunt-spritesmith/gulp.spritesmith, please see their cssVarMap documentation.
Example:
{
"frames": {
"mysprite.png": {
"frame": {
"x": 10,
"y": 20,
"w": 20,
"h": 30
}
},
// ...
},
"meta": {
"app": "spritesheet-templates",
// ...
"image": "nested/dir/spritesheet.png",
"scale": 1,
"size": {
"w": 80,
"h": 100
}
}
}

As noted in the Templates section, these can inherit from existing templates via handlebars-layouts conventions (e.g. {{#extend "scss"}}). An example can be found in the Examples section.
String - Key to store template under for reference via options.formatString - Handlebars template to use for formatting

In this example, we will process a template with retina data.
var templater = require('spritesheet-templates');
templater({
sprites: [{
name: 'github', x: 0, y: 0, width: 10, height: 20
}, {
name: 'twitter', x: 10, y: 20, width: 20, height: 30
}, {
name: 'rss', x: 30, y: 50, width: 50, height: 50
}],
// Note that the retina sprites are in the same order as `sprites`
retina_sprites: [{
name: 'github@2x', x: 0, y: 0, width: 20, height: 40
}, {
name: 'twitter@2x', x: 20, y: 40, width: 40, height: 60
}, {
name: 'rss@2x', x: 60, y: 100, width: 100, height: 100
}],
spritesheet: {
width: 80, height: 100, image: 'url/path/to/spritesheet.png'
},
retina_spritesheet: {
width: 160, height: 200, image: 'url/path/to/spritesheet@2x.png'
},
retina_groups: [{
name: 'github', index: 0
}, {
name: 'twitter', index: 1
}, {
name: 'rss', index: 2
}]
}, {format: 'scss_retina'}); /*
$github-name: 'github';
$github-x: 0px;
...
$twitter-2x-name: 'twitter@2x';
$twitter-2x-x: 20px;
...
$rss-group-name: 'rss';
$rss-group: ('rss', $rss, $rss-2x, );
$retina-groups: ($github-group, $twitter-group, $rss-group, );
*/
In this example, we will extend the SCSS template to output a minimal set of template data.
It should be noted that we must include the JSON front matter from the original template we are inheriting from to preserve default casing and options.
scss-minimal.handlebars:
{
// Default options
'functions': true,
'variableNameTransforms': ['dasherize']
}
{{#extend "scss"}}
{{#content "sprites"}}
{{#each sprites}}
${{strings.name}}: ({{px.x}}, {{px.y}}, {{px.offset_x}}, {{px.offset_y}}, {{px.width}}, {{px.height}}, {{px.total_width}}, {{px.total_height}}, '{{{escaped_image}}}', '{{name}}', );
{{/each}}
{{/content}}
{{#content "spritesheet"}}
${{spritesheet_info.strings.name_sprites}}: ({{#each sprites}}${{strings.name}}, {{/each}});
