hyphenopoly
Advanced tools
Hyphenopoly.js is a JavaScript-polyfill for hyphenation in HTML: it hyphenates text if the user agent does not support CSS-hyphenation at all or not for the required languages and it is a Node.js-module.
The package consists of the following parts:
Place all code for Hyphenopoly at the top of the header (immediately after the <title> tag) to ensure resources are loaded as early as possible.
You'll have to insert two script blocks. In the first block provide the initial configurations for Hyphenopoly_Loader as inline script. In the second block load Hyphenopoly_Loader.js as external script.
Also, don't forget to enable CSS hyphenation.

Let's go through this example step by step:
Make sure your page is encoded as utf-8.
Hyphenopoly_Loader.js needs some information to run. This information is provided in a globally accessible Object called Hyphenopoly. Hyphenopoly_Loader.js and (if necessary) Hyphenopoly.js will add other methods and properties only to this object – there will be no other global variables/functions beyond this object.
The Hyphenopoly object must have exactly one property called require which itself is an object containing at least one nameValuePair where the name is a language code string (Some patterns are region-specific. See the patterns directory for supported languages. E.g. just using en won't work, use either en-usor en-gb) and the value is a long word string in that language (preferably more than 12 characters long).
Hyphenator_Loader.js will feature test the client (aka browser, aka user agent) for CSS-hyphens support for the given languages with the given words respectively. In the example above it will test if the client supports CSS-hyphenation for latin. If your page contains more than just one language just add more lines.
If you want to force the usage of Hyphenopoly.js for a language (e.g. for testing purposes) write "FORCEHYPHENOPOLY" instead of the long word.
Hyphenopoly_Loader.js tests if the browser supports CSS hyphenation for the language(s) given in Hyphenopoly.require. If one of the given languages isn't supported it automatically hides the documents contents and loads Hyphenopoly.js and the necessary patterns. Hyphenopoly.js – once loaded – will hyphenate the elements according to the settings and unhide the document when it's done. If something goes wrong and Hyphenopoly.js is unable to unhide the document Hyphenopoly_Loader.js has a timeout that kicks in after some time (defaults to 1000ms) and unhides the document and writes a message to the console.
If the browser supports all required languages the script deletes the Hyphenopoly-object and terminates without further ado.
Hyphenopoly by default hyphenates elements (and their children) with the classname .hyphenate. Don't forget to enable CSS-hyphenation for the classes eventually handled by Hyphenopoly.
Install:
npm i hyphenopoly
"use strict";
const hyphenopoly = require("hyphenopoly");
const hyphenator = hyphenopoly.config({
"require": ["de", "en-us"],
"hyphen": "•",
"exceptions": {
"en-us": "en-han-ces"
}
});
async function hyphenate_en(text) {
const hyphenateText = await hyphenator.get("en-us");
console.log(hyphenateText(text));
}
async function hyphenate_de(text) {
const hyphenateText = await hyphenator.get("de");
console.log(hyphenateText(text));
}
hyphenate_en("hyphenation enhances justification.");
hyphenate_de("Silbentrennung verbessert den Blocksatz.");
The algorithm used for hyphenation was developed by Franklin M. Liang for TeX. It works more or less like this:
Example:
Hyphenation
h y p h e n a t i o n
h y3p h
h e2n
h e n a4
h e n5a t
1n a
n2a t
1t i o
2i o
o2n
h0y3p0h0e2n5a4t2i0o2n
Hy-phen-ation
The patterns are precomputed and available for many languages on CTAN. Hyphenopoly.js uses a proprietary binary format (including pattern licence, metadata and the patterns). Patterns are computed from a large list of hyphenated words by a program called patgen. They aim to find some hyphenation points – not all – because it's better to miss a hyphenation point then to have some false hyphenation points. Most patterns are really good but none is error free.
These pattern vary in size. This is mostly due to the different linguistic characteristics of the languages.
Hyphenator.js (https://github.com/mnater/Hyphenator) started 2007 and had evolved ever since. But web browsers have evolved much more! Almost all of them support native hyphenation (https://developer.mozilla.org/en-US/docs/Web/CSS/hyphens) for a specific set of languages (https://developer.mozilla.org/en-US/docs/Web/CSS/hyphens#Browser_compatibility). So it was time for something new!
Hyphenopoly.js is based on Hyphenator.js (they share some code) but - in favor of simplicity and speed – lacks many features of Hyphenator.js. Most of these features aren't needed in modern webdesign anymore:
If you need one of those features use Hyphenator.js – or give some feedback and proof that the feature is really useful and should be implemented in Hyphenopoly.js
On the other hand Hyphenopoly has a much finer-grained configuration system that allows you to make settings based on CSS-classes. And last but not least it is faster than Hyphenator.js
