Package description

What is escape-string-regexp?

The escape-string-regexp package is used to escape any characters that have special meaning in regular expressions. It takes a string and escapes characters that could be interpreted in a regex pattern, allowing the string to be used within a regex without triggering its special behavior.

What are escape-string-regexp's main functionalities?

Escaping special characters in strings for use in regular expressions

This feature is useful when you want to create a regular expression that includes literal strings that may contain characters that would normally be interpreted as special regex tokens. By escaping these characters, they are treated as literals in the regex pattern.

const escapeStringRegexp = require('escape-string-regexp');
const escapedString = escapeStringRegexp('Hello. How are you?');
// escapedString would be 'Hello\. How are you\?'
