Escape RegExp special characters
$ npm install escape-string-regexp
const escapeStringRegexp = require('escape-string-regexp'); const escapedString = escapeStringRegexp('How much $ for a 🦄?'); //=> 'How much \\$ for a 🦄\\?' new RegExp(escapedString);
You can also use this to escape a string that is inserted into the middle of a regex, for example, into a character class.
