_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');
|
|
|
```
