# emoji-regex [](https://travis-ci.org/mathiasbynens/emoji-regex)
_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 v12](https://github.com/mathiasbynens/unicode-12.0.0). Because of this, the regular expression can easily be updated whenever new emoji are added to the Unicode standard.
## Installation
Via [npm](https://www.npmjs.com/):
```bash
npm install emoji-regex
```
In [Node.js](https://nodejs.org/):
```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:
```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');
```
