# emoji-regex [![Build status](https://travis-ci.org/mathiasbynens/emoji-regex.svg?branch=main)](https://travis-ci.org/mathiasbynens/emoji-regex)

_emoji-regex_ offers a regular expression to match all emoji symbols and sequences (including textual representations of emoji) as per the Unicode Standard.

This repository contains a script that generates this regular expression based on [Unicode data](https://github.com/node-unicode/node-unicode-data). 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/RGI_Emoji.js');
// 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
```

## Regular expression flavors

The package comes with three distinct regular expressions:

```js
// This is the recommended regular expression to use. It matches all
// emoji recommended for general interchange, as defined via the
// `RGI_Emoji` property in the Unicode Standard.
// https://unicode.org/reports/tr51/#def_rgi_set
// When in doubt, use this!
const emojiRegexRGI = require('emoji-regex/RGI_Emoji.js');

// This is the old regular expression, prior to `RGI_Emoji` being
// standardized. In addition to all `RGI_Emoji` sequences, it matches
// some emoji you probably don’t want to match (such as emoji component
// symbols that are not meant to be used separately).
const emojiRegex = require('emoji-regex/index.js');

// This regular expression matches even more emoji than the previous
// one, including emoji that render as text instead of icons (i.e.
// emoji that are not `Emoji_Presentation` symbols and that aren’t
// forced to render as emoji by a variation selector).
const emojiRegexText = require('emoji-regex/text.js');
```

Additionally, in environments which support ES2015 Unicode escapes, you may `require` ES2015-style versions of the regexes:

```js
const emojiRegexRGI = require('emoji-regex/es2015/RGI_Emoji.js');
const emojiRegex = require('emoji-regex/es2015/index.js');
const emojiRegexText = require('emoji-regex/es2015/text.js');
```

## For maintainers

### How to update emoji-regex after new Unicode Standard releases

1. Update the Unicode data dependency in `package.json` by running the following commands:

```sh
    # Example: updating from Unicode v12 to Unicode v13.
    npm uninstall @unicode/unicode-12.0.0
    npm install @unicode/unicode-13.0.0 --save-dev
    ````

1. Generate the new output:

```sh
    npm run build
    ```

1. Verify that tests still pass:

```sh
    npm test
    ```

1. Send a pull request with the changes, and get it reviewed & merged.

1. On the `main` branch, bump the emoji-regex version number in `package.json`:

```sh
    npm version patch -m 'Release v%s'
    ```

Instead of `patch`, use `minor` or `major` [as needed](https://semver.org/).

Note that this produces a Git commit + tag.

1. Push the release commit and tag:

```sh
    git push
    ```

Our CI then automatically publishes the new release to npm.
