This project is a port of emoji-mart by missive.

Dependencies

Latest version available for each version of Angular

| @ctrl/ngx-emoji-mart | Angular | | -------------------- | --------- | | 1.0.6 | 8.x | | 3.1.0 | 9.x | | 5.1.2 | 10.x 11.x | | 6.2.0 | 12.x 13.x | | 7.1.0 | 14.x | | 8.2.0 | 15.x | | current | >=16.x |

Components

Picker

Add PickerComponent to your module imports:

import { PickerComponent } from '@ctrl/ngx-emoji-mart';

@NgModule({
  imports: [PickerComponent],
})
export class AppModule {}

// Or if using standalone components

@Component({
  standalone: true,
  imports: [PickerComponent],
})
export class AppComponent {}

Import styles in styles.scss:

@import '@ctrl/ngx-emoji-mart/picker';

Or bundle those styles through angular.json configuration:

"build": {
  "options": {
    "styles": [
      "src/styles.scss",
      "node_modules/@ctrl/ngx-emoji-mart/picker.css"
    ]
  }
}

Now we can use the emoji-mart component:

<emoji-mart title="Pick your emoji…" emoji="point_up"></emoji-mart>
<emoji-mart set="emojione"></emoji-mart>
<emoji-mart (emojiClick)="addEmoji($event)"></emoji-mart>
<emoji-mart [style]="{ position: 'absolute', bottom: '20px', right: '20px' }"></emoji-mart>
<emoji-mart
  [i18n]="{ search: 'Recherche', categories: { search: 'Résultats de recherche', recent: 'Récents' } }"
></emoji-mart>

Emoji

Add EmojiComponent to your module or standalone component imports:

import { EmojiComponent } from '@ctrl/ngx-emoji-mart/ngx-emoji';

<ngx-emoji [emoji]="{ id: 'santa', skin: 3 }" size="16"></ngx-emoji>
<ngx-emoji emoji=":santa::skin-tone-3:" size="16"></ngx-emoji>
<ngx-emoji emoji="santa" set="emojione" size="16"></ngx-emoji>

Unsupported emojis fallback

Certain sets don’t support all emojis (i.e. Facebook doesn'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:

emojiFallback = (emoji: any, props: any) => (emoji ? `:${emoji.shortNames[0]}:` : props.emoji);

<ngx-emoji set="twitter" emoji="shrug" size="24" [fallback]="emojiFallback"></ngx-emoji>

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.

const customEmojis = [
  {
    name: 'Octocat',
    shortNames: ['octocat'],
    text: '',
    emoticons: [],
    keywords: ['github'],
    imageUrl: 'https://github.githubassets.com/images/icons/emoji/octocat.png',
  },
  {
    name: 'Test Flag',
    shortNames: ['test'],
    text: '',
    emoticons: [],
    keywords: ['test', 'flag'],
    spriteUrl: 'https://cdn.jsdelivr.net/npm/[email protected]/img/twitter/sheets-256/64.png',
    sheet_x: 1,
    sheet_y: 1,
    size: 64,
    sheetColumns: 61,
    sheetRows: 60,
  },
];

<emoji-mart [custom]="customEmojis"></emoji-mart>

Headless search

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

import { EmojiSearch } from '@ctrl/ngx-emoji-mart';

class ex {
  constructor(private emojiSearch: EmojiSearch) {
    this.emojiSearch.search('christmas').map(o => o.native);
    // => [🎄, 🎅🏼, 🔔, 🎁, ⛄️, ❄️]
  }
}

Display emoji as custom element

// $event is from (emojiClick)
const styles = this.emoji.emojiSpriteStyles($event.emoji.sheet, 'twitter'); // pass emoji sheet
const el = document.createElement('div');
Object.assign(el.style, styles); // apply styles to new element
document.body.appendChild(el);

Storage

By default EmojiMart will store user chosen skin and frequently used emojis in localStorage.

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 |
