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);

Other packages similar to word-wrap

wrap-ansi

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.

Usage

var wrap = require('word-wrap');

wrap('Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.');

Results in:

  Lorem ipsum dolor sit amet, consectetur adipiscing
  elit, sed do eiusmod tempor incididunt ut labore
  et dolore magna aliqua. Ut enim ad minim veniam,
  quis nostrud exercitation ullamco laboris nisi ut
  aliquip ex ea commodo consequat.

Options

options.width

Type: Number

Default: 50

The width of the text before wrapping to a new line.

Example:

wrap(str, {width: 60});

options.indent

Type: String

Default: `` (two spaces)

The string to use at the beginning of each line.

Example:

wrap(str, {indent: '      '});

options.newline

Type: String

Default: \n

The string to use at the end of each line.

Example:

wrap(str, {newline: '\n\n'});

options.escape

Type: function

Default: function(str){return str;}

An escape function to run on each line after splitting them.

Example:

var xmlescape = require('xml-escape');
wrap(str, {
  escape: function(string){
    return xmlescape(string);
  }
});

options.trim

Type: Boolean

Default: false

Trim trailing whitespace from the returned string. This option is included since .trim() would also strip the leading indentation from the first line.

Example:

wrap(str, {trim: true});

options.cut

Type: Boolean

Default: false

Break a word between any two letters when the word is longer than the specified width.

Example:

wrap(str, {cut: true});
