How use lozad with nuxt (vue) ? about lozad.js

[podlebar]

const observer = lozad(this.$el.querySelector('picture.lozad'), {
    rootMargin: '50px 0px',
    threshold: 0.1,
    load(el) {
    const sources = el.querySelectorAll('source')
    sources.forEach((source) => {
      source.setAttribute('srcset', source.getAttribute('data-srcset'))
    })
  }
})
observer.observe()

something like this made it work for me but i needed to change srcset attrib to data-srcset.
