emoji-regex offers a regular expression to match all emoji symbols (including textual representations of emoji) as per the Unicode Standard.
This repository contains a script that generates this regular expression based on the data from Unicode Technical Report #51. Because of this, the regular expression can easily be updated whenever new emoji are added to the Unicode standard.
Via npm:
bash
npm install emoji-regex
In Node.js:
```js const emojiRegex = require('emoji-regex'); // Note: because the regular expression has the global flag set, this module // exports a function that returns the regex rather than exporting the regular // expression itself, to make it impossible to (accidentally) mutate the // original regular expression.
const text = \u{231A}: β default emoji presentation character (Emoji_Presentation)
\u{2194}\u{FE0F}: βοΈ default text presentation character rendered as emoji
\u{1F469}: π© emoji modifier base (Emoji_Modifier_Base)
\u{1F469}\u{1F3FF}: π©πΏ emoji modifier base followed by a modifier;
const regex = emojiRegex();
let match;
while (match = regex.exec(text)) {
const emoji = match[0];
console.log(Matched sequence ${ emoji } β code points: ${ [...emoji].length });
}
```
Console output:
Matched sequence β β code points: 1
Matched sequence β β code points: 1
Matched sequence βοΈ β code points: 2
Matched sequence βοΈ β code points: 2
Matched sequence π© β code points: 1
Matched sequence π© β code points: 1
Matched sequence π©πΏ β code points: 2
Matched sequence π©πΏ β code points: 2
To match emoji in their textual representation as well (i.e. emoji that are not Emoji_Presentation symbols and that arenβt forced to render as emoji by a variation selector), require the other regex:
js
const emojiRegex = require('emoji-regex/text.js');
Additionally, in environments which support ES2015 Unicode escapes, you may require ES2015-style versions of the regexes:
js
const emojiRegex = require('emoji-regex/es2015/index.js');
const emojiRegexText = require('emoji-regex/es2015/text.js');
