[![FOSSA Status](https://app.fossa.io/api/projects/git%2Bgithub.com%2Fiamcal%2Femoji-data.svg?type=shield)](https://app.fossa.io/projects/git%2Bgithub.com%2Fiamcal%2Femoji-data?ref=badge_shield)

This project provides easy-to-parse data about emoji, along with a spritesheet-style 
images for use on the web.

The current version supports Emoji version 15.1 (Sept 2023)

You can see a catalog of the emoji data here: http://projects.iamcal.com/emoji-data/table.htm


## Installation

The git repo is pretty big (almost 4GB), but contains everything. If you want to use `npm`, you can:

    npm install emoji-datasource

This will only install the 32px full-fidelity spritesheets (with fallback images). If you want different
size sheets (16, 20 or 64px), quantized sheets (128 or 256 color), non-fallback (clean) sheets, or the
individual images (at 64px) then you'll need to install additional npm modules:

```bash
npm install emoji-datasource-apple
npm install emoji-datasource-google
npm install emoji-datasource-twitter
npm install emoji-datasource-facebook
```

You can also use it without downloading via [jsDelivr CDN](https://www.jsdelivr.com/package/npm/emoji-datasource?path=img)
(different sizes [here](https://www.jsdelivr.com/?query=emoji-datasource%20author%3A%20iamcal)).

## Using the data

The file you want is `emoji.json`. It contains an array of entries for emoji that 
look like this:

```json
[
    {
        "name": "WHITE UP POINTING INDEX",
        "unified": "261D-FE0F",
        "non_qualified": "261D",
        "docomo": null,
        "au": "E4F6",
        "softbank": "E00F",
        "google": "FEB98",
        "image": "261d.png",
        "sheet_x": 1,
        "sheet_y": 2,
        "short_name": "point_up",
        "short_names": [
            "point_up"
        ],
        "text": null,
        "texts": null,
        "category": "People & Body",
        "subcategory": "hand-single-finger",
        "sort_order": 170,
        "added_in": "1.4",
        "has_img_apple": true,
        "has_img_google": true,
        "has_img_twitter": true,
        "has_img_facebook": false,
        "skin_variations": {
            "1F3FB": {
                "unified": "261D-1F3FB",
                "image": "261d-1f3fb.png",
                "sheet_x": 1,
                "sheet_y": 3,
                "added_in": "6.0",
                "has_img_apple": true,
                "has_img_google": false,
                "has_img_twitter": false,
                "has_img_facebook": false,
            }
            ...
            "1F3FB-1F3FC": {
                ...
            }
        },
        "obsoletes": "ABCD-1234",
        "obsoleted_by": "5678-90EF"
    },
    ...
]
```

The meaning of each field is as follows:

| Fields | Description |
| ------ | ----------- |
| `name` | The offical Unicode name, in SHOUTY UPPERCASE. |
| `unified` | The Unicode codepoint, as 4-5 hex digits. Where an emoji needs 2 or more codepoints, they are specified like 1F1EA-1F1F8. For emoji that need to specifiy a variation selector (-FE0F), that is included here. |
| `non_qualified` | For emoji that also have usage without a variation selector, that version is included here (otherwise is null). |
| `docomo`, `au`,<br>`softbank`, `google` | The legacy Unicode codepoints used by various mobile vendors. |
| `image` | The name of the image file. |
| `sheet_x`, `sheet_y` | The position of the image in the spritesheets. |
| `short_name` | The commonly-agreed upon short name for the image, as supported in campfire, github etc via the :colon-syntax: |
| `short_names` | An array of all the known short names. |
| `text` | An ASCII version of the emoji (e.g. `:)`), or null where none exists. |
| `texts` | An array of ASCII emoji that should convert into this emoji. Each ASCII emoji will only appear against a single emoji entry. |
| `category`, `subcategory` | Category and sub-category group names. |
| `sort_order` | Global sorting index for all emoji, based on Unicode CLDR ordering. |
| `added_in` | Emoji version in which this codepoint/sequence was added (previously Unicode version). |
| `has_img_*` | A flag for whether the given image set has an image (named by the image prop) available. |
| `skin_variations` | For emoji with multiple skin tone variations, a list of alternative glyphs, keyed by the skin tone. For emoji that support multiple skin tones within a single emoji, each skin tone is separated by a dash character. |
| `obsoletes`, `obsoleted_by` | Emoji that are no longer used, in preference of gendered versions. |


## Understanding the spritesheets

For each image set (Apple, Google, etc) we generate several different "sprite sheets" - large images of all emoji stitched together.

Every emoji image in the sheet has a 1 pixel transparent border around it, so the 64px sheet is really made up of 66px squares, while the 16px sheet is really made up of 18px squares, etc.
You can find the position of any given image on a sheet using the `sheet_x` and `sheet_y` properties, as follows:

    x = (sheet_x * (sheet_size + 2)) + 1;
    y = (sheet_y * (sheet_size + 2)) + 1;

Inside the Git repo you'll find some sheets in the root directory and some in the `sheets-indexed-128`, `sheets-indexed-256` and `sheets-clean` directories.
In the NPM packages, you'll find them under the `img/{$set}/sheets*` paths. For example:

| Git Repo | NPM Packages |
| -------- | ------------ |
| /sheet_apple_16.png | /img/apple/sheets/16.png |
| /sheets-indexed-128/sheet_apple_16_indexed_128.png | /img/apple/sheets-128/16.png |
| /sheets-clean/sheet_apple_16_clean.png | /img/apple/sheets-clean/16.png |

In these examples, the image set is from Apple and the images are 16px on a side.
The sheets on the top row are 24 bit color, while the sheets in the middle row use an indexed color palette with only 128 colors.
This makes the image much smaller, but sacrifices a lot of quality.
Both 128 color and 256 color sheets are provided.
The sheets on the bottom row do not contain fallbacks for missing images, so the Google sheet only contains Google images (and no Apple fallbacks).
This means that some images are replaced with the fallback character (a question mark), but the usage rights are simpler.


## Version history

See [CHANGES.md](CHANGES.md)


## Image Sources

Images are extracted from their sources and this library attempts to track the latest
available versions. If you're looking for older versions of Apple or Android images
(such as the Hairy Heart) then you'll need to look at previous revisions.

| Image Set | Source Version                                                  | Supported Emoji | Missing Images |
| --------- | --------------------------------------------------------------- | --------------- | -------------- |
| Apple     | iOS 17.4 beta                                                   | Emoji 15.1      | 3              |
| Google    | [Noto Emoji](https://github.com/googlefonts/noto-emoji), v2.042 | Emoji 15.1      | 0              |
| Twitter   | [Twemoji (fork)](https://github.com/jdecked/twemoji), v15.0.3   | Emoji 15.0      | 118            |
| Facebook  | v9, fetched 2024-02-05                                          | Emoji 15.0      | 142            |

missing emoji (see the spritesheet section above for more details).
