Installation

npm i widow-js

Use case

Good use case: Removing widows from dynamics text for which you don't control.

Not so good use case: Remove widows from static site for which you are too lazy to remove yourself. But you know... no judgement here 🤷🏻‍♂️

How to use

Import widow-js

import Widow from 'widow-js';

Initializing will automatically remove widows with your options.

const widow = new Widow({words: 4, elements: 'p, span', warnings: false});

If you need to remove widows from more elements later, use the removeWidowedElements method. Note: Widow will cache elements already transformed previously to avoid extra words wrapping.

widow.removeWidowedElements('#newtext, .someClass');

If you'd like to remove widows from a string use the removeWidowedText method

widow.removeWidowedText('Some text that could cause widows');

Here's how you would use removeWidowedText in the context of a react app

render() {
    const widow = new Widow({words: 2, warnings: false});
    const text = widow.removeWidowedText(this.props.text);
    return (
        <p>{text}</p>
    )
}

If your words prop is greater than the number of words in an element, Widow will skip element.

Props

Property	default	Description
words	0	Number value > 1
elements	none	A DOMString containing one or more selectors to match against
warnings	false	Turn on/off warnings
