A constructor to process promo_items for sitemaps and RSS feeds. It supports sitemap image tag, rss media:content and enclosure tags. It handles images, galleries and videos objects and tries to handle them in a consistent way.

• BuildPromoItems.imageTag - generate image tag
• BuildPromoItems.mediaTag - generate content:media tag
• BuildPromoItems.enclosureTag - generate enclosure tag

BuildPromoItems() - The constructor, needs a new instance created first

this.parse(ANS, jmespathString, resizerKey, resizerURL, width, height, imageTitle, imageCaption, imageCredits, videoSelect) - pass in ANS and jmespath statement. If the jmespath search returns something it's type is used to call the correct object parser. this.gallery - process content_elements, calling this.image on each one this.image - process image, returning url, type, title, caption, credits, height, width this.video - process video, returning url, type, title, caption, credits, duration, filesize, height, width (of video), thumbnail

import { BuildPromoItems } from './promoItems'

const MyPromoItems = new BuildPromoItems()

const promo = MyBuildPromoItems.mediaTag(ans, promoItemsJmespath, resizerKey, resizerURL, resizeWidth, resizeHeight, imageTitle, imageCaption, imageCredits, videoSelect)

Using a constructor allows use of prototype inheritance to override functions

import { BuildPromoItems } from './promoItems'

const MyPromoItems() {
  BuildPromoItems.call(this)

  this.image(options) {
    // custom image logic here to override existing functionality
  }
}

const NewPromoItems = new MyPromoItems()

const promo = NewPromoItems.imageTag(ans, promoItemsJmespath, resizerKey, resizerURL, resizeWidth, resizeHeight, imageTitle, imageCaption, imageCredits, videoSelect)
