quill-emoji-parser

---

Checks for emojis shortcuts during typing and pasting and replace them by their visual counterpart.

Very much inspired by quill-magic-url and the answer to this Stack Overflow question. Default map is taken from Smile2Emoji 🙏.

With NPM or Yarn

npm install quill-emoji-parser

yarn add quill-emoji-parser

With default emojis map included

import Quill from 'quill';
import EmojiParser from 'quill-emoji-parser';

Quill.register('modules/emojiParser', EmojiParser);

With no emojis map included

import Quill from 'quill';
import EmojiParser from 'quill-emoji-parser/base';
// Optionally import default map.
// import { EmojiMap } from 'quill-emoji-parser/default-map';

Quill.register('modules/emojiParser', EmojiParser);

Usage

Basic usage with no options and default map:

const quill = new Quill(editor, {
  modules: {
    // When module was imported with map included (default).
    emojiParser: true,

    // When module was imported with
    // import EmojiParser from 'quill-emoji-parser/base;
    // import { EmojiMap } from 'quill-emoji-parser/default-map;
    emojiParser: {
      map: EmojiMap,
    },

    // When module was included with script tags, to use default map.
    emojiParser: {
      map: EmojiMap.default,
    },
  },
});

Usage with custom options:

const quill = new Quill(editor, {
  modules: {
    emojiParser: {
      // Will remove shortcuts between ':'.
      bypassShortcuts: /:[a-z0-9_-]*:/i,
      // Will remove specific emojis.
      bypassEmojis: ['😈', '😜'],

      // For other options, see below...
    },
  },
});

Options

When importing full package with default map, all options are undefined or false by default. If module was imported without map (ie. ... from 'quill-emoji-parser/base'), you need to explicitly provide a map.

export interface EmojiParserOptions {
  // A custom map to use (mandatory when importing 'base' package).
  map?: Record<string, string>;
  // Shortcuts to be bypassed.
  bypassShortcuts?: RegExp | Array<string> | string;
  // Emojis to be bypassed.
  bypassEmojis?: RegExp | Array<string> | string;
  // The `onblur` behavior.
  parseOnBlur?: boolean;

  // Fired when plugin is instantiated. Gives access to some of its methods.
  onInstance?: (instance: EmojiParserInstance) => void;
  // Fired before parsing the clipboard content.
  onBeforePaste?: (node?: string, delta?: typeof Delta) => void;
  // Fired after parsing the clipboard content.
  onPasted?: (node?: string, delta?: typeof Delta) => void;
  // Fired before parsing typed text.
  onBeforeTextChange?: (delta?: typeof Delta) => void;
  // Fired after parsing typed text.
  onTextChanged?: (delta?: typeof Delta) => void;
  // Fired before each parsed shortcut.
  onBeforeUpdate?: (shortcut?: string, emoji?: string) => boolean | undefined;
  // Fired after a shortcut has been parsed.
  onUpdated?: (
    shortcut?: string,
    emoji?: string,
    delta?: typeof Delta,
    selection?: RangeStatic | null
  ) => void;
}

map

Imports a custom shortcut-to-replacement map. That means that you can eventually use quill-emoji-parser as a... anything parser... With some limitations... Use at your own risk!

To avoid importing the full package when providing a custom map: > import EmojiParser from 'quill-emoji-parser/base';

Record<string, string>;

Example

const myMap = {
  smile: '😄', // A sentence like 'I smile everyday!' will be transformed in 'I 😄 everyday!'
};

// ...

modules: {
  emojiParser: {
    map: myMap;
  }
}

bypassShortcuts

Disallow the transformation of some shortcuts from the emoji map. In the example below :poop: will not be parsed, but :hankey: will. Note that the string will be kept, unlike in bypassEmojis that will delete the pasted emoji from the content.

RegExp | Array<string> | string;

Example

// ...

modules: {
    emojiParser: {
        bypassShortcuts: /(:([^:]+):)/gi,
    }

    // or

    emojiParser: {
        // Strings separated by space.
        bypassShortcuts: ':open_mouth: :poop:'
    }

    // or

    emojiParser: {
        // Array of strings.
        bypassShortcuts: [':open_mouth:', ':poop:']
    }
}

bypassEmojis

Remove some emojis from the emoji map. That means that typed shortcut will not be parsed, and that a pasted blacklisted emoji will be deleted. For example, typing or pasting :poop: or :hankey: will not be parsed, but will be kept as text, and pasting 💩 will simply be deleted from the content.

RegExp | Array<string> | string;

Example

// ...

modules: {
    emojiParser: {
        // Removes some emojis...
        bypassEmojis: /\p{Emoji_Presentation}/gu,
    }

    // or

    emojiParser: {
        // Strings separated by space.
        bypassEmojis: '😮 💩'
    }

    // or

    emojiParser: {
        // Array of strings.
        bypassEmojis: ['😮', '💩']
    }
}

parseOnBlur

Performs a last check before the editor lose focus.

boolean;

Example

// ...

modules: {
  emojiParser: {
    parseOnBlur: true,
  }
}

onInstance

Function called when the module has been instantiated. The returned EmojiParserInstance object exposes some methods to dynamically change the module behavior.

onInstance?: (instance: EmojiParserInstance) => void;

export interface EmojiParserInstance {
  // Refresh the whole content by performing a kind of copy/paste action.
  refresh: () => void;
  // Dynamically add or remove shortcuts to be bypassed.
  // When a bypassed shortcut is removed, note that enterign a space after a shortcut will
  // trigger parse function.
  bypassShortcuts: (
    shortcuts?: RegExp | Array<string> | string
  ) => Record<string, string> | undefined;
  // Dynamically add or remove emojis to be bypassed.
  // Same behavior.
  bypassEmojis: (
    shortcuts?: RegExp | Array<string> | string
  ) => Record<string, string> | undefined;
  // Dynamically change the `onblur` behavior.
  parseOnBlur: (value: boolean) => void;
}

Example

let emojiParser: EmojiParserInstance;

// ...

modules: {
  emojiParser: {
    onInstance(instance: EmojiParserInstance) {
        emojiParser = instance;
    }
  }
}

// ...

button.addEventListener('click', () => {
    emojiParser.refresh();
});

input.addEventListener('change', () => {
    emojiParser.bypassShortcuts(input.value);
});

onBeforePaste

Function called before parsing pasted text. At this time, you still can modify node and delta.

(node?: string, delta?: Delta) => void

Example

// ...

modules: {
    emojiParser: {
        onBeforePaste(node: string, delta: Delta) {
            // The original node
            console.log(node);
            // The original Delta.
            console.log(delta);
        }
    }
}

onPasted

Function called after parsing pasted text. Gives the resulting node and delta of the transformation.

(node?: string, delta?: Delta) => void

Example

// ...

modules: {
    emojiParser: {
        onPasted(node: string, delta: Delta) {
            // The parsed node
            console.log(node);
            // The parsed Delta.
            console.log(delta);
        }
    }
}

onBeforeTextChange

Function called when a character was typed, before parsing. No check was done yet, but we're sure that there is a Delta to check, and that it contains an insert of type string that is not only a space.

(delta?: Delta) => void;

Example

// ...

modules: {
    emojiParser: {
        onBeforeTextChange(delta: Delta) {
            // The original Delta.
            console.log(delta);
        }
    }
}

onTextChanged

Function called when a character was typed, after parsing. It returns the new Delta.

(delta?: Delta) => void;

Example

// ...

modules: {
    emojiParser: {
        onTextChanged(delta: Delta) {
            // The parsed Delta.
            console.log(delta);
        }
    }
}

onBeforeUpdate

Function called for each found emoji. It is the place to put conditions to further parsing. Returning false will bypass the shortcut-to-emoji transformation.

(shortcut?: string, emoji?: string) => boolean;

Example

// ...

modules: {
    emojiParser: {
        onBeforeUpdate(shortcut: string, emoji: string) {
            if (shortcut === ':poop') return false;
            if (emoji === '💩') return false;

            return true;
        }
    }
}

onUpdated

Function called after each emoji is succesfully parsed and rendered by the Quill editor. This module uses queueMicrotask to get the selection after Quill updated the DOM. That means that something else could happen between the transformation and its rendering in the editor.

( shortcut?: string, emoji?: string, delta?: Delta, selection?: RangeStatic | null) => void;

Example

// ...

modules: {
    emojiParser: {
        onUpdated(shortcut: string, emoji: string, delta: Delta, selection: RangeStatic | null) {
            // The shortcut that was parsed.
            console.log(shortcut);

            // The emoji found.
            console.log(emoji);

            // The modified delta.
            console.log(delta);

            // The selection after modification.
            console.log(selection);
        }
    }
}
