indent-string

What is indent-string?

The indent-string npm package is a utility that allows users to add indentation to the beginning of each line in a string. This can be particularly useful for formatting multi-line strings or code snippets in a more readable manner. The package provides a simple interface to specify the number of spaces or the string to use for indentation, making it a versatile tool for text manipulation in Node.js applications.

What are indent-string's main functionalities?

Indenting with spaces

This feature allows you to indent each line of a given string with a specified number of spaces. In the code sample, the string 'Unicorn\nRainbow' is indented by 4 spaces.

const indentString = require('indent-string');

console.log(indentString('Unicorn\nRainbow', 4));
// Output:
//     Unicorn
//     Rainbow

Indenting with custom string

This feature enables indenting each line of a string with a custom string instead of spaces. In the example, the string 'Unicorn\nRainbow' is indented using the '♥' character, repeated 4 times as specified.

const indentString = require('indent-string');

console.log(indentString('Unicorn\nRainbow', 4, {indent: '♥'}));
// Output:
// ♥♥♥♥Unicorn
// ♥♥♥♥Rainbow

cli-boxes

While not directly similar, cli-boxes is a package that deals with text formatting in the terminal, offering a variety of box styles for CLI applications. It can be used in conjunction with indent-string for more complex text formatting tasks.
