picknick v6.0.1

about

A mixin friendly pager useful for setting up rotating slideshows.

setup

Download from the npm registry:

# Add to package.json
npm install picknick

usage

Instantiate with optional arguments for the wrap-around total and start position, plus a function to call with each index change. In return you get a plain object with prev() and next() methods attached for moving that index back and forth. For example,

import createPager from "picknick"

// Page through a dozen elements
const pager = createPager(12, 0, console.log)

// Decrement, prints 0
pager.prev()

// Increment, prints 1
pager.next()
