Sheet sizes

Sheets are served from unpkg, a global CDN that serves files published to npm.

Set	Size (`sheetSize: 16`)	Size (`sheetSize: 20`)	Size (`sheetSize: 32`)	Size (`sheetSize: 64`)
apple	334 KB	459 KB	1.08 MB	2.94 MB
facebook	322 KB	439 KB	1020 KB	2.50 MB
google	301 KB	409 KB	907 KB	2.17 MB
messenger	325 KB	449 KB	1.05 MB	2.69 MB
twitter	288 KB	389 KB	839 KB	1.82 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	558 KB
apple	486 KB
facebook	428 KB
google	485 KB
messenger	210 KB
twitter	486 KB

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

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

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

Local image requires

By default the picker source the emoji images online, this may not be the best solution and you may want to bundle the emojis with your app.

Set	Size (on disk)
all	1.5 MB
apple	708 KB
facebook	613 KB
google	712 KB
messenger	342 KB
twitter	722 KB

To use local image requires you need to install the individual sets you need in your project using the individual sets npm packages from https://github.com/iamcal/emoji-data#installation:

npm install emoji-datasource-apple
npm install emoji-datasource-google
npm install emoji-datasource-twitter
npm install emoji-datasource-facebook
npm install emoji-datasource-messenger

import { NimblePicker, NimbleEmoji } from 'emoji-mart-native'
import data from 'emoji-mart-native/data/messenger.json'
import dataRequires from 'emoji-mart-native/data/local-images/messenger'

const {emojis: localEmojis} = dataRequires

<NimblePicker set='messenger' data={data} useLocalImages={localEmojis} />
<NimbleEmoji emoji='santa' set='messenger' data={data} useLocalImages={localEmojis} />

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:

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

Custom emojis

You can provide custom emojis which will show up in their own category.

import { Picker, NimbleEmoji, getEmojiDataFromCustom } from 'emoji-mart-native'

const customEmojis = [
  {
    name: 'Octocat',
    short_names: ['octocat'],
    text: '',
    emoticons: [],
    keywords: ['github'],
    imageUrl: 'https://assets-cdn.github.com/images/icons/emoji/octocat.png?v7'
  },
  {
    name: 'Trollface',
    short_names: ['troll', 'trollface'],
    text: '',
    emoticons: [],
    keywords: ['troll'],
    localImage: require('assets/trollface.png')
  },
]

<Picker custom={customEmojis} />

const emoji = getEmojiDataFromCustom('troll', customEmojis, emojiData);

<NimbleEmoji
  data={emojiData}
  useLocalImages={emojiRequires}
  custom={customEmojis}
  skin={emoji.skin || null}
  set={emojiSet}
  emoji={emoji}
/>

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.

import { Picker } from 'emoji-mart'

const notFound = () => <Image style={{width: 48, height: 48}} source={{ uri: "https://assets-cdn.github.com/images/icons/emoji/octocat.png?v7" }} />

<Picker notFound={notFound} />

Custom category emojis

You can provide custom emojis for the category anchors. You only need to supply the ones you want changed from the default ones.

import { Picker } from 'emoji-mart'

const categoryEmojis = {
  recent: 'fire',
  people: 'see_no_evil',
  nature: 'beetle',
  foods: 'kiwifruit',
  activity: 'table_tennis_paddle_and_ball',
  places: 'airplane',
  objects: 'postal_horn',
  symbols: 'copyright',
  flags: 'triangular_flag_on_post',
  custom: 'hammer_and_wrench',
}

<Picker categoryEmojis={categoryEmojis} />

Headless search

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

import { emojiIndex } from 'emoji-mart-native'

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

With custom data

import data from 'emoji-mart-native/datasets/messenger'
import { NimbleEmojiIndex } from 'emoji-mart-native'

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

Get emoji data from Native

You can get emoji data from native emoji unicode using the getEmojiDataFromNative util function.

import { getEmojiDataFromNative, Emoji } from 'emoji-mart-native'
import data from 'emoji-mart-native/data/google.json'

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

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

Example of `emojiData` object:

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

Storage

By default EmojiMartNative 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.

import { store } from 'emoji-mart-native'

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 Native return more results than most emoji picker, they’re more accurate and sorted by relevance.

Emoticons

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

Results intersection

For better results, Emoji Mart Native split search into words and only returns results matching both terms.

Fully customizable

Anchors color, title and default emoji

Emojis sizes and length

Default skin color

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

It can however be overwritten as per user preference.

Multiple sets supported

Apple / Google / Twitter / Messenger / Facebook

Not opinionated

Emoji Mart Native 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 EmojiMartNative.Emoji component. You could also use emoji.colons to insert text into a textarea or emoji.native to use the emoji.

Development
