transliteration
Advanced tools
Unicode to ACSII transliteration / slugify module for node.js, browser, Web Worker, ReactNative and CLI.
The 'transliteration' npm package provides utilities for converting text between different scripts, particularly useful for converting non-Latin scripts to Latin scripts. It supports various transliteration schemes and can handle a wide range of languages.
Basic Transliteration
This feature allows you to convert text from non-Latin scripts to Latin scripts. In this example, Chinese characters are transliterated to their Latin equivalents.
const { transliterate } = require('transliteration');
const text = '你好，世界';
const result = transliterate(text);
console.log(result); // Output: 'Ni Hao , Shi Jie'Slugify
This feature converts text into a URL-friendly slug. It is particularly useful for creating SEO-friendly URLs from non-Latin scripts.
const { slugify } = require('transliteration');
const text = '你好，世界';
const result = slugify(text);
console.log(result); // Output: 'ni-hao-shi-jie'Custom Transliteration
This feature allows you to define custom mappings for transliteration. In this example, specific Cyrillic characters are mapped to their Latin equivalents.
const { transliterate } = require('transliteration');
const text = 'Привет, мир';
const customMap = { 'и': 'i', 'е': 'e', 'в': 'v' };
const result = transliterate(text, { customMap });
console.log(result); // Output: 'Privet, mir'The 'transliterator' package provides similar functionality for converting text between different scripts. It supports a wide range of languages and offers customizable transliteration schemes. Compared to 'transliteration', it may offer more flexibility in defining custom rules.
The 'unidecode' package is another alternative for transliterating Unicode text to ASCII. It is particularly known for its simplicity and ease of use. However, it may not support as many languages or offer as much customization as 'transliteration'.
The 'diacritics' package focuses on removing diacritical marks from text, converting it to a simpler form. While it doesn't offer full transliteration capabilities, it is useful for normalizing text. It is more specialized compared to 'transliteration'.
Transliteration / slugify module for node.js, browser, Web Worker, ReactNative and CLI. It provides the ability to transliterate UTF-8 characters into corresponding pure ASCII; so they can be safely displayed, used as URL slugs or file names.
npm install transliteration --save
import { transliterate as tr, slugify } from 'transliteration';
tr('你好, world!'); // Ni Hao , world!
slugify('你好, world!'); // ni-hao-world

transliteration has a good browser compatibility with all major browsers (including IE 6-8 if used with es5-shim).
npm install transliteration -g
transliterate 你好 # Ni Hao
slugify 你好 # ni-hao
import { transliterate, slugify } from 'transliteration/src/main/browser';
###1.0.0
Please note that the code has been entirely refactored since version 1.0.0. Be careful when you plan to upgrade from v0.1.x or v0.2.x to v1.0.x
Changes:
options parameter of transliterate now is an Object (In 0.1.x it's a string unknown).transliterate.config and slugify.config.[?] instead of ?.window.transl and windnow.slugify. Other global variables are removed.Transliterates the string str and return the result. Characters which this module doesn't recognise will be defaulted to the placeholder from the unknown argument in the configuration option, defaults to [?].
Options: (optional)
{
/* Unicode characters that are not in the database will be replaced with `unknown` */
unknown: '[?]', // default: [?]
/* Custom replacement of the strings before transliteration */
replace: { source1: target1, source2: target2, ... }, // Object form of argument
replace: [[source1, target1], [source2, target2], ... ], // Array form of argument
/* Strings in the ignore list will be bypassed from transliteration */
ignore: [str1, str2] // default: []
}
transliterate.config([optionsObj])
Bind options globally so any following calls will be using optoinsObj by default. If optionsObj argument is omitted, it will return current default option object.
transliterate.config({ replace: [['你好', 'Hello']] });
transliterate('你好, world!'); // Result: 'Hello, world!'. This equals transliterate('你好, world!', { replace: [['你好', 'Hello']] });
Example
import { transliterate as tr } from 'transliteration';
tr('你好，世界'); // Ni Hao , Shi Jie
tr('Γεια σας, τον κόσμο'); // Geia sas, ton kosmo
tr('안녕하세요, 세계'); // annyeonghaseyo, segye
tr('你好，世界', { replace: {你: 'You'}, ignore: ['好'] }) // You 好, Shi Jie
tr('你好，世界', { replace: [['你', 'You']], ignore: ['好'] }) // You 好, Shi Jie (option in array form)
// or use configurations
tr.config({ replace: [['你', 'You']], ignore: ['好'] });
tr('你好，世界') // You 好, Shi Jie
// get configurations
console.log(tr.config());
Converts Unicode string to slugs. So it can be safely used in URL or file name.
Options: (optional)
{
/* Whether to force slags to be lowercased */
lowercase: false, // default: true
/* Separator of the slug */
separator: '-', // default: '-'
/* Custom replacement of the strings before transliteration */
replace: { source1: target1, source2: target2, ... },
replace: [[source1, target1], [source2, target2], ... ], // default: []
/* Strings in the ignore list will be bypassed from transliteration */
ignore: [str1, str2] // default: []
}
If options is not provided, it will use the above default values.
slugify.config([optionsObj])
Bind options globally so any following calls will be using optoinsObj by default. If optionsObj argument is omitted, it will return current default option object.
slugify.config({ replace: [['你好', 'Hello']] });
slugify('你好, world!'); // Result: 'hello-world'. This equals slugify('你好, world!', { replace: [['你好', 'Hello']] });
Example:
import { slugify } from 'transliteration';
slugify('你好，世界'); // ni-hao-shi-jie
slugify('你好，世界', { lowercase: false, separator: '_' }); // Ni_Hao_Shi_Jie
slugify('你好，世界', { replace: {你好: 'Hello', 世界: 'world'}, separator: '_' }); // hello_world
slugify('你好，世界', { replace: [['你好', 'Hello'], ['世界', 'world']], separator: '_' }); // hello_world (option in array form)
slugify('你好，世界', { ignore: ['你好'] }); // 你好shi-jie
// or use configurations
slugify.config({ lowercase: false, separator: '_' });
slugify('你好，世界'); // Ni_Hao_Shi_Jie
// get configurations
console.log(slugify.config());
transliteration can be loaded as an AMD / CommonJS module, or as global variables (UMD).
When using it in the browser, by default it will create global variables under window object:
transl('你好, World'); // window.transl
// or
slugify('Hello, 世界'); // window.slugify
If the variable names conflict with other libraries in your project or you prefer not to use global variables, use noConfilict() before loading libraries which contain the conflicting variables.:
Load the library globally
var tr = transl.noConflict();
console.log(transl); // undefined
tr('你好, World'); // Ni Hao , World
var slug = slugify.noConfilict();
slug('你好, World'); // ni-hao-world
console.log(slugify); // undefined

transliteration supports almost all common languages whereas there might be quirks in some specific languages. For example, Kanji characters in Japanese will be transliterated as Chinese Pinyin. I couldn't find a better way to distinguish Chinese Hanzi and Japanese Kanji. So if you would like to romanize Japanese Kanji, please consider kuroshiro.
If you find any issues, please raise a GitHub issue. Thanks!
