#### Sheet sizes
Sheets are served from [unpkg](https://unpkg.com), a global CDN that serves files published to [npm](https://www.npmjs.com).

| Set       | Size (`sheetSize: 16`) | Size (`sheetSize: 20`) | Size (`sheetSize: 32`) | Size (`sheetSize: 64`) |
| --------- | ---------------------- | ---------------------- | ---------------------- | ---------------------- |
| apple     | 334 KB                 | 459 KB                 | 1.08 MB                | 2.94 MB                |
| emojione  | 315 KB                 | 435 KB                 | 1020 KB                | 2.33 MB                |
| facebook  | 322 KB                 | 439 KB                 | 1020 KB                | 2.50 MB                |

#### Datasets
While all sets are available by default, you may want to include only a single set data to reduce the size of your bundle.

| Set       | Size (on disk) |
| --------- | -------------- |
| all       | 570 KB         |
| apple     | 484 KB         |
| emojione  | 485 KB         |
| facebook  | 421 KB         |
| google    | 483 KB         |
| messenger | 197 KB         |
| twitter   | 484 KB         |

To use these data files (or any other custom data), use the `NimblePicker` component:

```js
import data from 'emoji-mart/data/messenger.json'
import { NimblePicker } from 'emoji-mart'

<NimblePicker set='messenger' data={data} />
```

#### Examples of `emoji` object:
```js
{
  id: 'smiley',
  name: 'Smiling Face with Open Mouth',
  colons: ':smiley:',
  text: ':)',
  emoticons: [
    '=)',
    '=-)'
  ],
  skin: null,
  native: '😃'
}

{
  id: 'santa',
  name: 'Father Christmas',
  colons: ':santa::skin-tone-3:',
  text: '',
  emoticons: [],
  skin: 3,
  native: '🎅🏼'
}

{
  id: 'octocat',
  name: 'Octocat',
  colons: ':octocat:',
  text: '',
  emoticons: [],
  custom: true,
  imageUrl: 'https://github.githubassets.com/images/icons/emoji/octocat.png'
}

```

### Emoji
```jsx
import { Emoji } from 'emoji-mart'

<Emoji emoji={{ id: 'santa', skin: 3 }} size={16} />
<Emoji emoji=':santa::skin-tone-3:' size={16} />
<Emoji emoji='santa' set='emojione' size={16} />
```

| Prop | Required | Default | Description |
| ---- | :------: | ------- | ----------- |
| **emoji** | ✓ | | Either a string or an `emoji` object |
| **size** | ✓ | | The emoji width and height. |
| **native** | | `false` | Renders the native unicode emoji |
| **onClick** | | | Params: `(emoji, event) => {}` |
| **onLeave** | | | Params: `(emoji, event) => {}` |
| **onOver** | | | Params: `(emoji, event) => {}` |
| [**fallback**](#unsupported-emojis-fallback) | | | Params: `(emoji, props) => {}` |
| **set** | | `apple` | The emoji set: `'apple', 'google', 'twitter', 'emojione'` |
| **sheetSize** | | `64` | The emoji [sheet size](#sheet-sizes): `16, 20, 32, 64` |
| **backgroundImageFn** | | ```((set, sheetSize) => `https://unpkg.com/emoji-datasource@3.0.0/sheet_${set}_${sheetSize}.png`)``` | A Fn that returns that image sheet to use for emojis. Useful for avoiding a request if you have the sheet locally. |
| **skin** | | `1` | Skin color: `1, 2, 3, 4, 5, 6` |
| **tooltip** | | `false` | Show emoji short name when hovering (title) |
| [**html**](#using-with-dangerouslysetinnerhtml) | | `false` | Returns an HTML string to use with `dangerouslySetInnerHTML` |

#### Unsupported emojis fallback
Certain sets don’t support all emojis (i.e. Messenger & Facebook don’t support `:shrug:`). By default the Emoji component will not render anything so that the emojis’ don’t take space in the picker when not available. When using the standalone Emoji component, you can however render anything you want by providing the `fallback` props.

To have the component render `:shrug:` you would need to:

```js
<Emoji
  set={'messenger'}
  emoji={'shrug'}
  size={24}
  fallback={(emoji, props) => {
    return emoji ? `:${emoji.short_names[0]}:` : props.emoji
  }}
/>
```

#### Using with `dangerouslySetInnerHTML`
The Emoji component being a [functional component](https://medium.com/missive-app/45-faster-react-functional-components-now-3509a668e69f), you can call it as you would call any function instead of using JSX. Make sure you pass `html: true` for it to return an HTML string.

```js
<span dangerouslySetInnerHTML={{
  __html: Emoji({
    html: true
    set: 'apple'
    emoji: '+1'
    size: 24
  })
}}></span>
```

#### Using with `contentEditable`
Following the `dangerouslySetInnerHTML` example above, make sure the wrapping `span` sets `contenteditable="false"`.

```js
<div contentEditable={true}>
  Looks good to me

  <span contentEditable={false} dangerouslySetInnerHTML={{
    __html: Emoji({
      html: true
      set: 'apple'
      emoji: '+1'
      size: 24
    })
  }}></span>
</div>
```

## Custom emojis
You can provide custom emojis which will show up in their own category. You can either use a single image as imageUrl or use a spritesheet as shown in the second object.

```js
import { Picker } from 'emoji-mart'

const customEmojis = [
  {
    name: 'Octocat',
    short_names: ['octocat'],
    text: '',
    emoticons: [],
    keywords: ['github'],
    imageUrl: 'https://github.githubassets.com/images/icons/emoji/octocat.png'
  },
  {
    name: 'Test Flag',
    short_names: ['test'],
    text: '',
    emoticons: [],
    keywords: ['test', 'flag'],
    spriteUrl: 'https://unpkg.com/emoji-datasource-twitter@4.0.4/img/twitter/sheets-256/64.png',
    sheet_x: 1,
    sheet_y: 1,
    size: 64,
    sheetColumns: 52,
    sheetRows: 52,
  },
]

<Picker custom={customEmojis} />
```

## Not Found
You can provide a custom Not Found object which will allow the appearance of the not found search results to change. In this case, we change the default 'sleuth_or_spy' emoji to Octocat when our search finds no results.

```js
import { Picker } from 'emoji-mart'

const notFound = () => <img src='https://github.githubassets.com/images/icons/emoji/octocat.png' />

<Picker notFound={notFound} />
```

## Custom icons
You can provide custom icons which will override the default icons.

```js
import { Picker } from 'emoji-mart'

const customIcons = {
  categories: {
    recent: () => <img src='https://github.githubassets.com/images/icons/emoji/octocat.png' />,
    foods: () => <svg role="img" viewBox="0 0 24 24" xmlns="http://www.w3.org/2000/svg"><path d="M0 0l6.084 24H8L1.916 0zM21 5h-4l-1-4H4l3 12h3l1 4h13L21 5zM6.563 3h7.875l2 8H8.563l-2-8zm8.832 10l-2.856 1.904L12.063 13h3.332zM19 13l-1.5-6h1.938l2 8H16l3-2z"/></svg>,
    people: () => <svg xmlns="http://www.w3.org/2000/svg" width="16" height="16" viewBox="0 0 16 16"><path d="M3 2l10 6-10 6z"></path></svg>
  }
}

<Picker icons={customIcons} />
```

## Headless search
The `Picker` doesn’t have to be mounted for you to take advantage of the advanced search results.

```js
import { emojiIndex } from 'emoji-mart'

emojiIndex.search('christmas').map((o) => o.native)
// => [🎄, 🎅🏼, 🔔, 🎁, ⛄️, ❄️]
```

## Get emoji data from Native
You can get emoji data from native emoji unicode using the `getEmojiDataFromNative` util function.

```js
import { getEmojiDataFromNative, Emoji } from 'emoji-mart'
import data from 'emoji-mart/data/all.json'

const emojiData = getEmojiDataFromNative('🏊🏽‍♀️', 'apple', data)

<Emoji
  emoji={emojiData}
  set={'apple'}
  skin={emojiData.skin || 1}
  size={48}
/>
```

#### Example of `emojiData` object:
```js
emojiData: {
  "id": "woman-swimming",
  "name": "Woman Swimming",
  "colons": ":woman-swimming::skin-tone-4:",
  "emoticons": [],
  "unified": "1f3ca-1f3fd-200d-2640-fe0f",
  "skin": 4,
  "native": "🏊🏽‍♀️"
}
```

### With custom data
```js
import data from 'emoji-mart/datasets/messenger'
import { NimbleEmojiIndex } from 'emoji-mart'

let emojiIndex = new NimbleEmojiIndex(data)
emojiIndex.search('christmas')
```

## Storage
By default EmojiMart will store user chosen skin and frequently used emojis in `localStorage`. That can however be overwritten should you want to store these in your own storage.

```js
import { store } from 'emoji-mart'

store.setHandlers({
  getter: (key) => {
    // Get from your own storage (sync)
  },

  setter: (key, value) => {
    // Persist in your own storage (can be async)
  }
})
```

Possible keys are:

| Key | Value | Description |
| --- | ----- | ----------- |
| skin | `1, 2, 3, 4, 5, 6` | |
| frequently | `{ 'astonished': 11, '+1': 22 }` | An object where the key is the emoji name and the value is the usage count |
| last | 'astonished' | (Optional) Used by `frequently` to be sure the latest clicked emoji will always appear in the “Recent” category |

## Features
### Powerful search
#### Short name, name and keywords
Not only does **Emoji Mart** return more results than most emoji picker, they’re more accurate and sorted by relevance.

<img width="338" alt="summer" src="https://user-images.githubusercontent.com/436043/32532567-179f1be4-c400-11e7-885e-df6e9b52c665.png">

#### Emoticons
The only emoji picker that returns emojis when searching for emoticons.

<img width="338" alt="emoticons" src="https://user-images.githubusercontent.com/436043/32532570-1be0dd28-c400-11e7-90cd-f33396277602.png">

#### Results intersection
For better results, **Emoji Mart** split search into words and only returns results matching both terms.

<img width="338" alt="high-five" src="https://user-images.githubusercontent.com/436043/32532573-1f4a9d1e-c400-11e7-8656-921bc6c09732.png">

### Fully customizable
#### Anchors color, title and default emoji
<img width="338" alt="customizable-color" src="https://user-images.githubusercontent.com/436043/32532582-302dc9e4-c400-11e7-9b97-f37c447231ca.png"><br><img width="338" alt="pick-your-emoji" src="https://user-images.githubusercontent.com/436043/32532585-34546faa-c400-11e7-9c9d-fbbe830d4368.png">

#### Emojis sizes and length
<img width="296" alt="size-and-length" src="https://user-images.githubusercontent.com/436043/32532590-381f67de-c400-11e7-86f6-328e30d6b116.png">

#### Default skin color
As the developer, you have control over which skin color is used by default.

<img width="205" alt="skins" src="https://user-images.githubusercontent.com/436043/32532858-0a559560-c402-11e7-8680-f77f780a5a49.png">

It can however be overwritten as per user preference.

#### Multiple sets supported
Apple / Google / Twitter / EmojiOne / Messenger / Facebook

<img width="214" alt="sets" src="https://user-images.githubusercontent.com/436043/33786868-d4226e60-dc38-11e7-840a-e4cf490f5f4a.png">

## Not opinionated
**Emoji Mart** doesn’t automatically insert anything into a text input, nor does it show or hide itself. It simply returns an `emoji` object. It’s up to the developer to mount/unmount (it’s fast!) and position the picker. You can use the returned object as props for the `EmojiMart.Emoji` component. You could also use `emoji.colons` to insert text into a textarea or `emoji.native` to use the emoji.

## Usage outside React

**Emoji Mart** can be used with React alternatives such as [Preact](https://preactjs.com/), [Inferno](https://www.infernojs.org/), and [react-lite](https://github.com/Lucifier129/react-lite).

Furthermore, you can use it as a [custom element](https://developer.mozilla.org/en-US/docs/Web/Web_Components/Using_custom_elements) using [remount](https://github.com/rstacruz/remount), meaning that you can use it within any JavaScript framework (or vanilla JS).

For an end-to-end example of how to do this, see [emoji-mart-outside-react](https://github.com/nolanlawson/emoji-mart-outside-react).

## Optimizing for production

### Modern/ES builds

**Emoji Mart** comes in three flavors:

```
dist
dist-es
dist-modern
```

- `dist` is the standard build with the highest level of compatibility.
- `dist-es` is the same, but uses ES modules for better tree-shaking.
- `dist-modern` removes features not needed in modern evergreen browsers (i.e. latest Chrome, Edge, Firefox, and Safari).

The default builds are `dist` and `dist-es`. (In Webpack, one or the other will be chosen based on your [resolve main fields](https://webpack.js.org/configuration/resolve/#resolve-mainfields).)
If you want to use `dist-modern`, you must explicitly import it:

```js
import { Picker } from 'emoji-mart/dist-modern/index.js'
```

Using something like Babel, you can transpile the modern build to suit your own needs.

### Removing prop-types

To remove [prop-types](https://github.com/facebook/prop-types) in production, use [babel-plugin-transform-react-remove-prop-types](https://github.com/oliviertassinari/babel-plugin-transform-react-remove-prop-types):

```bash
npm install --save-dev babel-plugin-transform-react-remove-prop-types
```

Then add to your `.babelrc`:

```json
"plugins": [
  [
    "transform-react-remove-prop-types",
    {
      "removeImport": true,
      "additionalLibraries": [
        "../../utils/shared-props"
      ]
    }
  ]
]
```

You'll also need to ensure that Babel is transpiling `emoji-mart`, e.g. [by not excluding `node_modules` in `babel-loader`](https://github.com/babel/babel-loader#usage).

## Development

```bash
yarn build
```

In two separate tabs:

```bash
yarn start
yarn storybook
```

The storybook is hosted at `localhost:6006`, and the code will be built on-the-fly.
