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:
npm install emoji-regexIn Node.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}: ⌚ default emoji presentation character (Emoji_Presentation)
\u{2194}\u{FE0F}: ↔️ default text presentation character rendered as emoji
\u{1F469}: 👩 emoji modifier base (Emoji_Modifier_Base)
\u{1F469}\u{1F3FF}: 👩🏿 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 } — code points: ${ [...emoji].length }`);
}Console output:
Matched sequence ⌚ — code points: 1
Matched sequence ⌚ — code points: 1
Matched sequence ↔️ — code points: 2
Matched sequence ↔️ — code points: 2
Matched sequence 👩 — code points: 1
Matched sequence 👩 — code points: 1
Matched sequence 👩🏿 — code points: 2
Matched sequence 👩🏿 — code points: 2
To match emoji in their textual representation as well (i.e. emoji that are not Emoji_Presentation symbols and that aren’t forced to render as emoji by a variation selector), require the other regex:
const emojiRegex = require('emoji-regex/text.js'); |
