## 💾 Data

Data required for the picker to work has been completely decoupled from the library. That gives developers the flexibility to better control their app bundle size and let them choose how and when this data is loaded. Data can be:

### Bundled directly into your codebase
- **Pros:** Picker renders instantly, data is available offline
- **Cons:** Slower initial page load (bigger file to load)

```sh
yarn add @emoji-mart/data
```

```js
import data from '@emoji-mart/data'
import { Picker } from 'emoji-mart'

new Picker({ data })
```

### Fetched remotely
- **Pros:** Data fetched only when needed, does not affect your app bundle size
- **Cons:** Network latency, doesn’t work offline (unless you configure a ServiceWorker)

```js
import { Picker } from 'emoji-mart'
new Picker({
  data: async () => {
    const response = await fetch(
      'https://cdn.jsdelivr.net/npm/@emoji-mart/data',
    )

    return response.json()
  }
})
```

In this example data is fetched from a content delivery network, but it could also be fetched from your own domain if you want to host the data.

## 🏪 Picker
### React
```sh
npm install --save emoji-mart @emoji-mart/data @emoji-mart/react
```

```js
import data from '@emoji-mart/data'
import Picker from '@emoji-mart/react'

function App() {
  return (
    <Picker data={data} onEmojiSelect={console.log} />
  )
}
```

### Browser
```html
<script src="https://cdn.jsdelivr.net/npm/emoji-mart@latest/dist/browser.js"></script>
<script>
  const pickerOptions = { onEmojiSelect: console.log }
  const picker = new EmojiMart.Picker(pickerOptions)

  document.body.appendChild(picker)
</script>
```

### Custom emojis
You can use custom emojis by providing an array of categories and their emojis. Emojis also support multiple skin tones and can be GIFs or SVGs.

```js
import data from '@emoji-mart/data'
import Picker from '@emoji-mart/react'

const custom = [
  {
    id: 'github',
    name: 'GitHub',
    emojis: [
      {
        id: 'octocat',
        name: 'Octocat',
        keywords: ['github'],
        skins: [{ src: './octocat.png' }],
      },
      {
        id: 'shipit',
        name: 'Squirrel',
        keywords: ['github'],
        skins: [
          { src: './shipit-1.png' }, { src: './shipit-2.png' }, { src: './shipit-3.png' },
          { src: './shipit-4.png' }, { src: './shipit-5.png' }, { src: './shipit-6.png' },
        ],
      },
    ],
  },
  {
    id: 'gifs',
    name: 'GIFs',
    emojis: [
      {
        id: 'party_parrot',
        name: 'Party Parrot',
        keywords: ['dance', 'dancing'],
        skins: [{ src: './party_parrot.gif' }],
      },
    ],
  },
]

function App() {
  return (
    <Picker data={data} custom={custom} />
  )
}
```

### Custom category icons
You can use custom category icons by providing an object with the category name as key and the icon as value. Currently supported formats are `svg` string and `src`. See [example](https://missiveapp.com/open/emoji-mart/example-categories.html).

```js
const customCategoryIcons = {
  categoryIcons: {
    activity: {
      svg: '<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 640 512"><path d="M57.89 397.2c-6.262-8.616-16.02-13.19-25.92-13.19c-23.33 0-31.98 20.68-31.98 32.03c0 6.522 1.987 13.1 6.115 18.78l46.52 64C58.89 507.4 68.64 512 78.55 512c23.29 0 31.97-20.66 31.97-32.03c0-6.522-1.988-13.1-6.115-18.78L57.89 397.2zM496.1 352c-44.13 0-79.72 35.75-79.72 80s35.59 80 79.72 80s79.91-35.75 79.91-80S540.2 352 496.1 352zM640 99.38c0-13.61-4.133-27.34-12.72-39.2l-23.63-32.5c-13.44-18.5-33.77-27.68-54.12-27.68c-13.89 0-27.79 4.281-39.51 12.8L307.8 159.7C262.2 192.8 220.4 230.9 183.4 273.4c-24.22 27.88-59.18 63.99-103.5 99.63l56.34 77.52c53.79-35.39 99.15-55.3 127.1-67.27c51.88-22 101.3-49.87 146.9-82.1l202.3-146.7C630.5 140.4 640 120 640 99.38z"/></svg>',

    people: {
      src: './people.png',
    },
  },
}
```

## 🙃 Emoji component
The emoji web component usage is the same no matter what library you use.

First, you need to make sure data has been initialized. You need to call this only once per page load. Note that if you call `init` like this, you don’t necessarily need to include data in your Picker props. It doesn’t hurt either, it will noop.

```js
import data from '@emoji-mart/data'
import { init } from 'emoji-mart'

init({ data })
```

Then you can use the emoji component in your HTML / JSX.

```html
<em-emoji id="+1" size="2em"></em-emoji>
<em-emoji id="+1" skin="2"></em-emoji>
<em-emoji shortcodes=":+1::skin-tone-1:"></em-emoji>
<em-emoji shortcodes=":+1::skin-tone-2:"></em-emoji>
```

### Attributes / Props
| Attribute | Example | Description |
| --------- | ------- | ----------- |
| **id** | `+1` | An emoji ID |
| **shortcodes** | `:+1::skin-tone-2:` | An emoji shortcode |
| **native** | `👍` | A native emoji |
| **size** | `2em` | The inline element size |
| **fallback** | `:shrug:` | A string to be rendered in case the emoji can’t be found |
| **set** | `native` | The emoji set: `native`, `apple`, `facebook`, `google`, `twitter` |
| **skin** | `1` | The emoji skin tone: `1`, `2`, `3`, `4`, `5`, `6` |

## 🕵️‍♀️ Headless search
You can search without the Picker. Just like the emoji component, `data` needs to be initialized first in order to use the search index.

```js
import data from '@emoji-mart/data'
import { init, SearchIndex } from 'emoji-mart'

init({ data })

async function search(value) {
  const emojis = await SearchIndex.search(value)
  const results = emojis.map((emoji) => {
    return emoji.skins[0].native
  })

  console.log(results)
}

search('christmas') // => ['🎄', '🇨🇽', '🧑‍🎄', '🔔', '🤶', '🎁', '☃️', '❄️', '🎅', '⛄']
```

## 🔬 Get emoji data from native
You can get emoji data from a native emoji. This is useful if you want to get the emoji ID from a native emoji. Just like the emoji component, `data` needs to be initialized first in order to retrieve the emoji data.

```js
import data from '@emoji-mart/data'
import { init, getEmojiDataFromNative } from 'emoji-mart'

init({ data })

getEmojiDataFromNative('🤞🏿').then(console.log)
/* {
  aliases: ['hand_with_index_and_middle_fingers_crossed'],
  id: 'crossed_fingers',
  keywords: ['hand', 'with', 'index', 'and', 'middle', 'good', 'lucky'],
  name: 'Crossed Fingers',
  native: '🤞🏿',
  shortcodes: ':crossed_fingers::skin-tone-6:',
  skin: 6,
  unified: '1f91e-1f3ff',
} */
```

## 🗺 Internationalization
EmojiMart UI supports [multiple languages](https://github.com/missive/emoji-mart/tree/main/packages/emoji-mart-data/i18n), feel free to open a PR if yours is missing.

```js
import i18n from '@emoji-mart/data/i18n/fr.json'
i18n.search_no_results_1 = 'Aucun emoji'

new Picker({ i18n })
```

Given the small file size, English is built-in and doesn’t need to be provided.

## 🤓 Built for modern browsers
EmojiMart relies on these APIs, you may need to include polyfills if you need to support older browsers:
