Richer

What is it?

This library is built on top of slater (which is a fork of shopify slate). It is based on the old implementation of the Timber depreciated richcart. The idea behind this comes from Slate and Timber both being tied to jQuery and wanting to build something that could be used independent of that.

Using It

We use richer to handle API requests to the shopify AJAX cart. How you implement it is entirely up to you. We expose a couple of common routes that allow you to easily handle updating/refreshing/generating your ajax cart.

I'll outline a number of examples in YOYO below

Initialize a cart

import RicherAPI from 'richer'

// Some DOM defaults
const defaults = {
  addToCart: '.js-add-to-cart', // classname
  addToCartForm: 'AddToCartForm', // id
  cartContainer: 'CartContainer', // id
  cartCounter: 'CartCounter', // id
  items: []
}

const config = Object.assign({}, defaults, options)

const dom = {
  addToCartForm: document.getElementById(config.addToCartForm),
  cartContainer: document.getElementById(config.cartContainer),
  cartCounter: document.getElementById(config.cartCounter)
}

RicherAPI.getCart(cartUpdateCallback)

// Updates a cart number and builds our cart
const cartUpdateCallback = (cart) => {
  updateCount(cart)
  buildCart(cart)
}

const updateCount = (cart) => {
  const counter = dom.cartCounter
  counter.innerHTML = cart.item_count
}

const buildCart = (cart) => {
  const cartContainer = dom.cartContainer
  cartContainer.innerHTML = null

  if (cart.item_count === 0) {
    cartContainer.innerHTML = `<p>We're sorry your cart is empty</p>`
    return
  }

  var el = cartBlock(cart.items, cart, update)

  function cartBlock (items, cart, qtyControl) {
    return yo`
      <div class='r-cart'>
        ${items.map((item, index) => {
          const product = cleanProduct(item, index, config)
          return yo`
            <div class="r-cart__product f jcb">
              <div>
                <img src='${product.image}' alt='${product.name}' />
              </div>
              <div class="r-cart__product_info">
                <h5><a href='${product.url}'>${product.name}</a></h5>
                ${product.variation ? yo`<span>${product.variation}</span>` : null}
                ${realPrice(product.discountsApplied, product.originalLinePrice, product.linePrice)}
                ${yo`
