Generate routes from data

Uses a .json file as base to generate route to this post or page.

Special behaviour for home slugs: We use / for the default lang home slug, /en/ for the english home etc.

⚠️ For now we cannot have a page with a permalink including home like /pages/something/home-sweet-home In the generateRoutesFromData process we remove all pages which include home. 🤷‍ Makes sense to be aware of that!

• options Object The options object to pass in (optional, default {langs:[],postTypes:{},dataPath:'',bundle:'',homeSlug:'home',errorPrefix:'error-'})
  • options.langs Array
  • options.postTypes Object
  • options.dataPath string

  • options.homeSlug string?
  • options.errorPrefix string?

generateRoutesFromData({
  langs: config.env.LANGS,
  postTypes: config.postTypes,
  dataPath: '../../../../../static/data',
  bundle: 'basic',
  homeSlug: config.env.HOMESLUG,
  errorPrefix: config.env.ERROR_PREFIX
})

Generates meta image info

Like the meta description the OG Image is generated from the page-wide options, but will use a more specific OG image on a page/post – if set. It uses the predefined size (social-share-large), which we defined in our WordPress image crops. 1280px x 720px. By defining those sizes, an image does not have to be inspected by a platform like facebook, because it does not know the size yet. This saves time.
