slug

What is slug?

The 'slug' npm package is a utility for creating URL-friendly slugs from strings. It converts strings into a format that can be safely used in URLs by removing or replacing special characters, spaces, and other non-URL-safe characters.

What are slug's main functionalities?

Basic Slug Creation

This feature allows you to create a basic slug from a string. It converts the string to lowercase and replaces spaces and special characters with hyphens.

const slug = require('slug');
const title = 'Hello World!';
const urlSlug = slug(title);
console.log(urlSlug); // Output: 'hello-world'

Custom Separator

This feature allows you to specify a custom separator instead of the default hyphen. In this example, underscores are used as separators.

const slug = require('slug');
const title = 'Hello World!';
const urlSlug = slug(title, { replacement: '_' });
console.log(urlSlug); // Output: 'hello_world'

Remove Special Characters

This feature automatically removes special characters from the string, making it URL-safe.

const slug = require('slug');
const title = 'Hello, World!';
const urlSlug = slug(title);
console.log(urlSlug); // Output: 'hello-world'

Multi-language Support

This feature supports multiple languages, converting non-Latin characters to their Latin equivalents.

const slug = require('slug');
const title = '你好，世界';
const urlSlug = slug(title);
console.log(urlSlug); // Output: 'ni-hao-shi-jie'

README

slug

slugifies every string, even when it contains unicode!

Make strings url-safe.

• respecting RFC 3986
• Comprehensive tests
• No dependencies (except the unicode table)
• Not in coffee-script (except the tests lol)
• Coerces foreign symbols to their english equivalent
• Works in browser (window.slug) and AMD/CommonJS-flavoured module loaders (except the unicode symbols unless you use browserify but who wants to download a ~2mb js file, right?)

npm install slug

example

var slug = require('slug')
var print = console.log.bind(console, '>')

print(slug('i ♥ unicode'))
// > i-love-unicode

print(slug('unicode ♥ is ☢')) // yes!
// > unicode-love-is-radioactive

print(slug('i ♥ unicode', '_')) // If you prefer something else then `-` as seperator
// > i_love_unicode

slug.charmap['♥'] = 'freaking love' // change default charmap or use option {charmap:{…}} as 2. argument
print(slug('I ♥ UNICODE').toLowerCase()) // If you prefer lower case
// > i-freaking-love-unicode

options

// options is either object or replacement (sets options.replacement)
slug('string', [{options} || 'replacement']);

slug.defaults = {
    replacement: '-',      // replace spaces with replacement
    symbols: true,         // replace unicode symbols or not
    charmap: slug.charmap, // replace special characters
};
