spritesheet-templates

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.

Getting Started

Install the module with: npm install spritesheet-templates

1// Compilation
2var templater = require('spritesheet-templates');
3templater({
4  sprites: [{
5    name: 'github', x: 0, y: 0, width: 10, height: 20
6  }, {
7    name: 'twitter', x: 10, y: 20, width: 20, height: 30
8  }, {
9    name: 'rss', x: 30, y: 50, width: 50, height: 50
10  }],
11  spritesheet: {
12    width: 80, height: 100, image: 'url/path/to/spritesheet.png'
13  }
14}, {format: 'stylus'}); /*

Documentation

spritesheet-templates exports the function templater as its module.exports.

`templater(data, options)`

Converter for spritesheet/sprite info into spritesheet

data Object - Container for data for template
- items Object[] - Deprecated alternative key to define data.sprites
- sprites Object[] - Array of objects with coordinate data about each sprite on the spritesheet
  - - Object - Container for sprite coordinate data
      - For reference, * symbolizes any index (e.g. data.sprites[0])
      - name String - Name to use for the image
      - x Number - Horizontal coordinate of top-left corner of image
      - y Number - Vertical coordinate of top-left corner of image
      - width Number - Horizontal length of image in pixels
      - height Number - Vertical length of image in pixels
- spritesheet Object - Information about spritesheet
  - width Number - Horizontal length of image in pixels
  - height Number - Vertical length of image in pixels
  - image String - URL to use for spritesheet
    - This will typically be used in background-image
    - For example, background-image: url({{spritesheet.image}});
- spritesheet_info Object - Optional container for metadata about spritesheet and its representation
  - name String - Prefix to use for all spritesheet variables
    - For example, icons will generate $icons-width/$icons-image/etc in a SCSS template
    - By default, this is spritesheet (e.g. $spritesheet-width, $spritesheet-image)
- Additional parameters for retina templates are documented in the Retina parameters section
options Object - Optional settings
- spritesheetName String - Deprecated alternative for spritesheet_info.name
- format String - Format to generate output in
  - We accept any format inside of the Templates section
    - Custom formats can be added via the custom methods
  - By default, we will use the css format
- formatOpts Mixed - Options to pass through to the formatter

Returns:

retVal String - Result from specified formatter

Retina parameters

retina 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}]).

data Object - Same container as defined above
- retina_sprites Object[] - Array of objects with coordinate data about each retina sprite for the retina spritesheet
  - Properties are retina equivalent of data.sprites
  - These should be in the same order as their normal complements
- retina_spritesheet Object - Information about retina spritesheet
  - Properties are retina equivalent of data.spritesheet
- retina_spritesheet_info Object - Optional container for metadata about retina_spritesheet and its representation
  - name String - Prefix to use for all retina spritesheet variables
    - For example, retina-icons will generate $retina-icons-width/$retina-icons-image/etc in a SCSS template
    - By default, this is retina-spritesheet (e.g. $retina-spritesheet-width, $retina-spritesheet-image)
- retina_groups Object[] - Array of objects that maps to normal and retina sprites
  - - Object - Container for data about sprite mapping
      - name String - Name to refer to mapping by
        
        This is typically used for CSS selectors and variable names
      - index Number - Index to look up corresponding normal/retina sprites from data.sprites/data.retina_sprites
- retina_groups_info Object - Optional container for metadata about retina_groups and its representation
  - name String - Name to use for retina_groups variable
    - For example, icon-groups will generate $icons-groups in a SCSS template
    - By default, this is retina-groups (e.g. $retina-groups)

Templates

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.

`css`

Ouput CSS variables as CSS rules.

Options:

cssSelector Function - Override mapping for CSS selector
- cssSelector should have signature function (sprite) { return 'selector'; }
- By default this will return '.icon-' + sprite.name
- It will receive sprite with all parameters designed for template

Handlebars blocks:

css is a Handlebars based template. We allow for overriding the following sections:

{{#content "sprites-comment"}} - Comment before CSS rules
{{#content "sprites"}} - CSS rules

Example:

1.icon-sprite1 {
2  background-image: url(nested/dir/spritesheet.png);
3  background-position: 0px 0px;
4  width: 10px;
5  height: 20px;
6}
7.icon-sprite2 {
8/* ... */

`json`

Output CSS variables in JSON format.

Example:

1{
2    "sprite1": {
3        "x": 0,
4        "y": 0,
5        "width": 10,
6        "height": 20,
7        "total_width": 80,
8        "total_height": 100,
9        "image": "nested/dir/spritesheet.png",
10        "offset_x": 0,
11        "offset_y": 0,
12        "px": {
13            "x": "0px",
14            "y": "0px",
15            "offset_x": "0px",
16            "offset_y": "0px",
17            "height": "20px",
18            "width": "10px",
19            "total_height": "100px",
20            "total_width": "80px"
21        },
22        "escaped_image": "nested/dir/spritesheet.png"
23    },
24    "sprite2": {
25    // ...

`json_array`

Output CSS variables as an array of objects.

Example:

1[
2    {
3        "name": "sprite1",
4        "x": 0,
5        "y": 0,
6        "width": 10,
7        "height": 20,
8        "total_width": 80,
9        "total_height": 100,
10        "image": "nested/dir/spritesheet.png",
11        "offset_x": 0,
12        "offset_y": 0,
13        "px": {
14            "x": "0px",
15            "y": "0px",
16            "offset_x": "0px",
17            "offset_y": "0px",
18            "height": "20px",

20            "total_height": "100px",
21            "total_width": "80px"
22        },
23        "escaped_image": "nested/dir/spritesheet.png"
24    },
25    {
26        "name": "sprite2",
27        // ...

`json_texture`

Output 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:

1// Input
2{
3  sprites: [{
4    frame_name: 'hello', name: 'github', x: 0, y: 0, width: 10, height: 20
5  }]
6}
7
8// Output
9{
10  frames: {
11    hello: {x: 0, y: 0, w: 10, h: 20}
12  }
13}

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:

1{
2    "frames": {
3        "mysprite.png": {
4            "frame": {
5                "x": 10,
6                "y": 20,
7                "w": 20,
8                "h": 30
9            }
10        },
11        // ...
12    },
13    "meta": {
14        "app": "spritesheet-templates",
15        // ...
16        "image": "nested/dir/spritesheet.png",
17        "scale": 1,
18        "size": {
19            "w": 80,
20            "h": 100
21        }
22    }
23}

`less`

- underscore.string: http://epeli.github.io/underscore.string/#api
  - We use chain which allows for toUpperCase and toLowerCase
  - http://epeli.github.io/underscore.string/#s-string-gt-chain

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.

name String - Key to store template under for reference via options.format
tmplStr String - Handlebars template to use for formatting
- This will receive data as its data (e.g. {{sprites}} is data.sprites)

`templater.addMustacheTemplate(name, tmplStr)`

Deprecated alias for templater.addHandlebarsTemplate

Examples

Retina configuration

In this example, we will process a template with retina data.

1var templater = require('spritesheet-templates');
2templater({
3  sprites: [{
4    name: 'github', x: 0, y: 0, width: 10, height: 20
5  }, {
6    name: 'twitter', x: 10, y: 20, width: 20, height: 30
7  }, {
8    name: 'rss', x: 30, y: 50, width: 50, height: 50
9  }],
10  // Note that the retina sprites are in the same order as `sprites`
11  retina_sprites: [{
12    name: 'github@2x', x: 0, y: 0, width: 20, height: 40
13  }, {
14    name: 'twitter@2x', x: 20, y: 40, width: 40, height: 60
15  }, {
16    name: 'rss@2x', x: 60, y: 100, width: 100, height: 100
17  }],
18  spritesheet: {
19    width: 80, height: 100, image: 'url/path/to/spritesheet.png'
20  },
21  retina_spritesheet: {
22    width: 160, height: 200, image: 'url/path/to/spritesheet@2x.png'
23  },
24  retina_groups: [{
25    name: 'github', index: 0
26  }, {
27    name: 'twitter', index: 1
28  }, {
29    name: 'rss', index: 2
30  }]
31}, {format: 'scss_retina'}); /*
32$github-name: 'github';
33$github-x: 0px;
34...
35$twitter-2x-name: 'twitter@2x';
36$twitter-2x-x: 20px;

38$rss-group-name: 'rss';
39$rss-group: ('rss', $rss, $rss-2x, );
40$retina-groups: ($github-group, $twitter-group, $rss-group, );

Inheriting from a template

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:

1{
2  // Default options
3  'functions': true,
4  'variableNameTransforms': ['dasherize']
5}
6
7{{#extend "scss"}}
8{{#content "sprites"}}
9{{#each sprites}}
10${{strings.name}}: ({{px.x}}, {{px.y}}, {{px.offset_x}}, {{px.offset_y}}, {{px.width}}, {{px.height}}, {{px.total_width}}, {{px.total_height}}, '{{{escaped_image}}}', '{{name}}', );
11{{/each}}
12{{/content}}
13{{#content "spritesheet"}}
14${{spritesheet_info.strings.name_sprites}}: ({{#each sprites}}${{strings.name}}, {{/each}});
15${{spritesheet_info.strings.name}}: ({{spritesheet.px.width}}, {{spritesheet.px.height}}, '{{{spritesheet.escaped_image}}}', ${{spritesheet_info.strings.name_sprites}}, );
16{{/content}}
17{{/extend}}

index.js:

1// Load in our dependencies
2var fs = require('fs');
3var templater = require('spritesheet-templates');
4
5// Register our new template
6var scssMinimalHandlebars = fs.readFileSync('scss-minimal.handlebars', 'utf8');
7templater.addHandlebarsTemplate('scss-minimal', scssMinimalHandlebars);
8
9// Run our templater
10templater({
11  sprites: [{
12    name: 'github', x: 0, y: 0, width: 10, height: 20
13  }, {
14    name: 'twitter', x: 10, y: 20, width: 20, height: 30
15  }, {

17  }],
18  spritesheet: {

20  }
21}, {format: 'scss-minimal'}); /*
