Update v2.1.0

  • Add requestAnimationFrame polyfill.
  • Now img lazyload detects horizontal direction automatically
  • Imporve perfomence, since the scroll event liseners were as many as pictures * 2 before, there is only two liseners now.

Update v2.1.1

  • Add .npmignore to exclude .babelrc

Update in V2.1.2

  • Preload, let you set a range to preload images before an image enters the viewport.
  • Rewrite with Typescript, add d.ts, make developing easier.

Update in V2.1.3

  • fix wrong export of typings

Next

  • Support partial-match image URLs, eg. pic.400px.jpg or pic.200px.jpg, let you switch resolution of images by some custom rules.
  • Maybe SSR.

    // speed: 20,
    // default 300, mostly, it's not necessary to set it
    time: 300,
    // unit:px, default 0, it allows the lazyload manager loads images(vertical) before an image appeard in screen
