💾 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)

yarn add @slidoapp/emoji-mart-data

import data from '@slidoapp/emoji-mart-data'
import { Picker } from '@slidoapp/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)

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

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.

import data from '@slidoapp/emoji-mart-data'
import Picker from '@slidoapp/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.

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.

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

init({ data })

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

<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.

import data from '@slidoapp/emoji-mart-data'
import { init, SearchIndex } from '@slidoapp/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.

import data from '@slidoapp/emoji-mart-data'
import { init, getEmojiDataFromNative } from '@slidoapp/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, feel free to open a PR if yours is missing.

import i18n from '@slidoapp/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.

📚 Examples

• Categories
• Custom emoji font
• Custom styles
• Emoji component
• Headless search
• Slack colors

🤓 Built for modern browsers

EmojiMart relies on these APIs, you may need to include polyfills if you need to support older browsers:

• Shadow DOM (MDN)
• Custom elements (MDN)
• IntersectionObserver (MDN)
• Async/Await (MDN)
