text-split v0.0.1

text-split

Text wrapping for type animations.

Install

$ npm install text-split --save

Why?

To address some prior art:

• Lettering.js - dependent on jQuery
• charming
  • less straightforward (child nodes are recursed through for text content)
  • less flexible (mandatory class and aria attributes are added, no per piece callback)

With only 1 method and 4 options, text-split offers the most control via the smallest API surface area.

Getting Started

import splitter from 'text-split'

// a target node is required
const target = document.querySelector('.heading')

// pass in the target node
// get back the newly created nodes wrapping the target text (in an array)
const created = splitter(target)

Read more about options below to handle more complex use cases.

Options

All options have defaults, as shown here:

const defaults = {
  a11y = true,
  delimeter = 'letter',
  each = null,
  element = 'span'
}

Each option is explained in further detail below:

• a11y
• delimeter
• each
• element

a11y

Enable (default) or disable setting of aria attributes on parent and created child nodes.

splitter(target, { a11y: false })

delimeter

Either letter (default) or word, indicating how to break up the target text before wrapping it.

splitter(target, { delimeter: 'word' })

each

A function that, if it exists, is called and passed:

• the created node, with appropriate textContent
• the 0-based node index (relative to the other created nodes)
• the DocumentFragment that stores the nodes created (thus far)

This is the fun part escape hatch.

splitter(target, {
  each: (node, index, frag) => {
    // add a class based on the index
    node.classList.add(`number-${index}`)

    // add a transition delay based on the index
    node.style.transitionDelay = `${index * .05}s`
  }
})

element

A tag name that is used to create the wrapper element for each piece of the text after it is split using the delimeter.

const divs = splitter(target, { element: 'div' })
