Module Init Pattern

init.js

export default types => (ctx = document) => {
  return {
    init () {
      for (let type in types) {
        const attr = 'data-' + type
        const nodes = [].slice.call(ctx.querySelectorAll(`[${attr}]`))

        for (let i = 0; i < nodes.length; i++) {
          try {
            require(types[type] + nodes[i].getAttribute(attr) + '.js').default(nodes[i])
            nodes[i].removeAttribute(attr)
          } catch (e) {
            console.error(e)
          }
        }
      }
    }
  }
}
