{\itshape 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 \href{https://github.com/mathiasbynens/unicode-12.0.0}{\texttt{ the data from Unicode v12}}. Because of this, the regular expression can easily be updated whenever new emoji are added to the Unicode standard.\hypertarget{md_sfcode_node_modules_karma_node_modules_emoji_regex_README_autotoc_md14995}{}\doxysection{Installation}\label{md_sfcode_node_modules_karma_node_modules_emoji_regex_README_autotoc_md14995}
Via \href{https://www.npmjs.com/}{\texttt{ npm}}\+:


\begin{DoxyCode}{0}
\DoxyCodeLine{npm install emoji-\/regex }

\end{DoxyCode}


In \href{https://nodejs.org/}{\texttt{ Node.\+js}}\+:


\begin{DoxyCode}{0}
\DoxyCodeLine{const emojiRegex = require('emoji-\/regex');}
\DoxyCodeLine{// Note: because the regular expression has the global flag set, this module}
\DoxyCodeLine{// exports a function that returns the regex rather than exporting the regular}
\DoxyCodeLine{// expression itself, to make it impossible to (accidentally) mutate the}
\DoxyCodeLine{// original regular expression.}
\DoxyCodeLine{}
\DoxyCodeLine{const text = `}
\DoxyCodeLine{\(\backslash\)u\{231A\}: ⌚ default emoji presentation character (Emoji\_Presentation)}
\DoxyCodeLine{\(\backslash\)u\{2194\}\(\backslash\)u\{FE0F\}: ↔️ default text presentation character rendered as emoji}
\DoxyCodeLine{\(\backslash\)u\{1F469\}: 👩 emoji modifier base (Emoji\_Modifier\_Base)}
\DoxyCodeLine{\(\backslash\)u\{1F469\}\(\backslash\)u\{1F3FF\}: 👩🏿 emoji modifier base followed by a modifier}
\DoxyCodeLine{`;}
\DoxyCodeLine{}
\DoxyCodeLine{const regex = emojiRegex();}
\DoxyCodeLine{let match;}
\DoxyCodeLine{while (match = regex.exec(text)) \{}
\DoxyCodeLine{  const emoji = match[0];}
\DoxyCodeLine{  console.log(`Matched sequence \$\{ emoji \} — code points: \$\{ [...emoji].length \}`);}
\DoxyCodeLine{\} }

\end{DoxyCode}


Console output\+:


\begin{DoxyCode}{0}
\DoxyCodeLine{Matched sequence ⌚ — code points: 1}
\DoxyCodeLine{Matched sequence ⌚ — code points: 1}
\DoxyCodeLine{Matched sequence ↔️ — code points: 2}
\DoxyCodeLine{Matched sequence ↔️ — code points: 2}
\DoxyCodeLine{Matched sequence 👩 — code points: 1}
\DoxyCodeLine{Matched sequence 👩 — code points: 1}
\DoxyCodeLine{Matched sequence 👩🏿 — code points: 2}
\DoxyCodeLine{Matched sequence 👩🏿 — code points: 2 }

\end{DoxyCode}


To match emoji in their textual representation as well (i.\+e. emoji that are not {\ttfamily Emoji\+\_\+\+Presentation} symbols and that aren’t forced to render as emoji by a variation selector), {\ttfamily require} the other regex\+:


\begin{DoxyCode}{0}
\DoxyCodeLine{const emojiRegex = require('emoji-\/regex/text.js'); }

\end{DoxyCode}


Additionally, in environments which support ES2015 Unicode escapes, you may {\ttfamily require} ES2015-\/style versions of the regexes\+:


\begin{DoxyCode}{0}
\DoxyCodeLine{const emojiRegex = require('emoji-\/regex/es2015/index.js');}
\DoxyCodeLine{const emojiRegexText = require('emoji-\/regex/es2015/text.js'); }

\end{DoxyCode}
