Slice-ansi is a useful npm package designed to slice a string that contains ANSI escape codes. ANSI escape codes are often used to style terminal text with color and other visual modifications. Slice-ansi allows you to cut these strings accurately, taking into account the non-displaying ANSI codes and ensuring that the output remains correct and visually as expected in your terminal.

How do you use slice-ansi?

Integration of slice-ansi into your projects is straightforward. You first need to install it using npm with the command npm install slice-ansi. You can use slice-ansi in your code by importing it along with any other dependencies you may have, such as chalk for styling your text. If we take a string stylized with chalk for instance:

import chalk from 'chalk';
import sliceAnsi from 'slice-ansi';

const string = 'The quick brown ' + chalk.red('fox jumped over ') +
	'the lazy ' + chalk.green('dog and then ran away with the unicorn.');

console.log(sliceAnsi(string, 20, 30));

In this example, the string is sliced between the 20th and 30th characters, taking into account the ANSI codes. The sliced portion will then be output using console.log.
