How to strip emojis from string in JavaScript

There are multiple ways how to strip emoji symbols from a string in JavaScript. Yet the combination of string.replace(), string.trim() methods and RegExp works best in the majority of the cases.

First of all, we use replace() and RegExp to remove any emojis from the string.

At this point, you might think that’s all that we need, but practically, we still need to handle cases where there is a sequence of emojis used which creates whitespace after truncation.

Then, we use replace() and RegExp once again. This time, we are only interested to remove multiple spaces. Worth mentioning that the starting and ending spaces will be kept and stripped down to a single space.

Finally, we use trim() to remove any surrounding spaces from the string.

1const stripEmojis = (str) =>
2  str
3    .replace(
4      /([\u2700-\u27BF]|[\uE000-\uF8FF]|\uD83C[\uDC00-\uDFFF]|\uD83D[\uDC00-\uDFFF]|[\u2011-\u26FF]|\uD83E[\uDD10-\uDDFF])/g,
5      ''
6    )
7    .replace(/\s+/g, ' ')
8    .trim();
