Package description

What is emoji-regex?

The emoji-regex npm package provides a regular expression to match all Emoji-only symbols as per the Unicode Standard. This package is useful for processing text that contains emojis, allowing developers to identify, validate, or manipulate emojis within strings.

What are emoji-regex's main functionalities?

Matching emojis in a string

This code sample demonstrates how to use emoji-regex to find all emojis in a given string. The regex is executed against a string containing emojis, and it will match each emoji character or sequence.

/(emojiRegex())/g.exec('I ❤️ emoji!')

Replacing emojis in a string

This code sample shows how to replace all emojis in a string with a specific word or character. In this case, every emoji in the string is replaced with the word 'emoji'.

'I ❤️ emoji!'.replace(emojiRegex(), 'emoji')

Counting emojis in a string

This code sample is used to count the number of emojis in a string. The match function returns an array of all emojis found, and the length property of the array indicates the total number of emojis.

emoji-regex Build status emoji-regex on npm

emoji-regex offers a regular expression to match all emoji symbols and sequences (including textual representations of emoji) as per the Unicode Standard. It’s based on emoji-test-regex-pattern, which generates (at build time) the regular expression pattern based on the Unicode Standard. As a result, emoji-regex can easily be updated whenever new emoji are added to Unicode.


Via npm:

npm install emoji-regex

In 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();
for (const match of text.matchAll(regex)) {
  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

For maintainers

How to update emoji-regex after new Unicode Standard releases

  1. Update emoji-test-regex-pattern as described in its repository.

  2. Bump the emoji-test-regex-pattern dependency to the latest version.

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

    # Example: updating from Unicode v13 to Unicode v14.
    npm uninstall @unicode/unicode-13.0.0
    npm install @unicode/unicode-14.0.0 --save-dev
  4. Generate the new output:

    npm run build
  5. Verify that tests still pass:

    npm test

How to publish a new release

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

    npm version patch -m 'Release v%s'

    Instead of patch, use minor or major as needed.

    Note that this produces a Git commit + tag.

  2. Push the release commit and tag:

    git push && git push --tags

    Our CI then automatically publishes the new release to npm.
