Package description

What is ansi-regex?

The ansi-regex npm package is used to create regular expressions to match ANSI escape codes, which are used to format output in terminal with colors, background colors, styles like bold or underline, and other text effects.

What are ansi-regex's main functionalities?

Matching ANSI escape codes

This code sample demonstrates how to use ansi-regex to match ANSI escape codes in a string. The string contains the ANSI escape codes for underlining text, followed by the word 'cake', and then the reset code to stop the underlining. The ansiRegex function is called to generate a regular expression that matches these codes.

"\u001B[4mcake\u001B[0m".match(ansiRegex());
