limax

Node.js module to generate URL slugs. Another one? This one cares about i18n and transliterates non-Latin scripts to conform to the RFC3986 standard. Mostly API-compatible with similar modules.

limax

(Yet another) Node.js module to generate URL slugs, also known as clean URLs, user-friendly URLs and SEO-friendly URLs.

The difference?

This module includes Romanisation of non-Latin scripts. Give it a string of text in pretty much any major world language and it will convert it to valid characters, conforming to RFC3986, for use within the path element of a URL.

Currently supports, but not limited to, the following scripts:

  • Latin: e.g. English, français, Deutsch, español, português
  • Cyrillic: e.g. Русский язык, български език, українська мова
  • Chinese: e.g. 官话, 吴语 (converts to Latin script using tone number Pinyin)
  • Japanese: e.g. ひらがな, カタカナ (converts to Romaji using Hepburn)

Based on number of npm downloads, the most popular Node.js module for generating slugs is slug, which claims it "slugifies even utf-8 chars!" You may be pleased to discover that all characters in a utf-8 encoded string are "utf-8 chars"!

This module depends on the speakingurl module and remains mostly API-compatible with both it and the more popular slug module.

If you already use either the speakingurl or slug modules, you can probably swap in limax without changing the logic in your code.

Oh, and limax is the Latin word for slug.

Install

npm install limax

Usage

var slug = require("limax");

slug(text)

var latin = slug("i ♥ latin"); // i-love-latin
var cyrillic = slug("Я люблю русский"); // ya-lyublyu-russkij
var pinyin = slug("我爱官话"); // wo3-ai4-guan1-hua4
var romaji = slug("私は ひらがな が大好き"); // ha-hiragana-gaki

slug(text, options)

options:

  • replacement: char to replace whitespace with, defaults to - (provides API compatibility with the slug module)
  • separator: equivalent to replacement (provides API compatibility with the speakingurl module)
  • lang: ISO 639-1 two-letter language code, defaults to auto-detected language
var strich = slug("Ich ♥ Deutsch", {lang: "de"}); // ich-liebe-deutsch
var unterstreichen1 = slug("Ich ♥ Deutsch", {lang: "de", replacement: "_"}); // i_liebe_deutsch
var unterstreichen2 = slug("Ich ♥ Deutsch", {lang: "de", separator: "_"}); // i_liebe_deutsch

slug(text, replacement)

Provided to support backwards-compatibility with the slug module.

var underscore = slug("i ♥ unicode", "_"); // i_love_unicode
