word-wrap

What is word-wrap?

The word-wrap npm package is a simple utility that allows you to wrap words to a specified width. This can be particularly useful when dealing with text formatting in console applications or when generating text content that needs to adhere to certain width constraints.

What are word-wrap's main functionalities?

Basic word wrapping

This feature allows you to wrap a long string of text to a specified width. The 'width' option defines the maximum length of the lines in the output.

const wrap = require('word-wrap');
const text = 'This is a long piece of text that needs to be wrapped.';
const wrappedText = wrap(text, {width: 20});
console.log(wrappedText);

Custom indentation

This feature allows you to add custom indentation to the beginning of each line in the wrapped text. The 'indent' option specifies the string to use for indentation.

const wrap = require('word-wrap');
const text = 'This text will have an indentation.';
const wrappedText = wrap(text, {width: 20, indent: '    '});
console.log(wrappedText);

Trimming

This feature enables the trimming of leading and trailing whitespace from the input text before wrapping. The 'trim' option is a boolean that activates this behavior.

const wrap = require('word-wrap');
const text = '   This text has extra spaces that will be trimmed.   ';
const wrappedText = wrap(text, {width: 20, trim: true});
console.log(wrappedText);

Custom newline character

This feature allows you to specify a custom newline character to be used in the wrapped text. The 'newline' option lets you define what characters to use for line breaks.

const wrap = require('word-wrap');
const text = 'This text will use a custom newline character.';
const wrappedText = wrap(text, {width: 20, newline: '\n\n'});
console.log(wrappedText);

Cut long words

This feature allows you to specify whether long words should be cut to fit the specified width. The 'cut' option is a boolean that, when true, will break a word that is longer than the specified width.

const wrap = require('word-wrap');
const text = 'A verylongwordthatneedstobewrapped.';
const wrappedText = wrap(text, {width: 10, cut: true});
console.log(wrappedText);

wrap-ansi is a package similar to word-wrap but with additional support for ANSI escape codes, which are commonly used for coloring and styling text in terminal applications. This makes wrap-ansi more suitable for applications that require maintaining text styles after wrapping.

cli-wrap

cli-wrap is another package that provides text wrapping functionality with a focus on CLI applications. It offers features like word wrapping, centering text, and more, but it is not as widely used or as well-known as word-wrap.

text-table

text-table is a package that allows for creating text-based tables with aligned columns. While it is not a direct alternative to word-wrap, it does include text wrapping as part of its functionality to ensure that table cells display text correctly.
