parcel-plugin-data-src

ParcelJS plugin to bundle resources defined in data-src and data-srcset attributes.

This is particularly useful when doing lazyloading of images, which doesn't directly place the image path in the src attribute.

Installation

$ npm install --save-dev parcel-plugin-data-src

Example

<picture>
  <source
    data-srcset="
      ./images/image-lg.webp 1000w,
      ./images/image-md.webp 500w,
      ./images/image-sm.webp 250w"
    sizes="100vw"
    type="image/webp"
  >
  <img
    data-srcset="
      ./images/image-lg.jpg 1000w,
      ./images/image-md.jpg 500w,
      ./images/image-sm.jpg 250w"
    sizes="100vw"
    data-src="./images/image-lg.jpg"
    src="./images/image-placeholder.jpg"
  >
</picture>

By default, Parcel will only bundle ./images/image-placeholder.jpg since it's defined in the src attribute.

Using this plugin, the following resosurces that are defined in data-srcset and data-src will also be bundled.

• ./images/image-lg.webp
• ./images/image-md.webp
• ./images/image-sm.webp
• ./images/image-lg.jpg
• ./images/image-md.jpg
• ./images/image-sm.jpg
