## What it is
emoji-regex is a JavaScript library that provides a regular expression to match all emoji symbols and sequences as per the Unicode Standard. It is generated from Unicode data at build time, making it easy to update whenever new emoji are added to Unicode.

## Use cases
- match all emoji in a string
- find emoji symbols in user input
- replace emoji with images in text
- validate that a string contains only emoji
- count emoji occurrences in text
- strip emoji from text content
- detect emoji sequences including modifiers and ZWJ

## When to choose
- you need a standards-compliant, deterministic emoji matcher tied to a specific Unicode version
- you need to guarantee an image asset exists for every possibly matched emoji
- you want a well-maintained library that tracks new Unicode emoji releases

## When to avoid
- you need a lighter-weight, non-deterministic general emoji pattern (consider emoji-regex-xs instead)
- you need emoji matching in a non-JavaScript language
- you need emoji rendering or image assets, not just matching

## Facets
- artifact type: library
- maturity: stable
- function: parser, nlp, developer-tools
- domain: text-editors, developer-tools
- platform: cross-platform
- tags: emoji, regex, unicode, text-processing, natural-language-processing, nodejs, javascript
