This is how BBC News currently implements it's Image Enhancer for responsive images. Note: this is a completely rebuilt version of the code so the BBC's original source code doesn't actually look anything like the below example.

The BBC has a server-side image service which provides developers with multiple sized versions of any image they request. It works in a similar fashion to http://placehold.it/ but it also handles the image ratios returned (where as placehold.it doesn't).

The original BBC News process (and my re-working of the script) follows roughly these steps...

  • Create new instance of ImageEnhancer
  • Change any divs within the page (which have a class of delayed-image-load) into a transparent GIF using a Base64 encoded string.
    • We set the width & height HTML attributes of the image to the required size
    • We know what size the image needs to be because each div has custom data-attr set server-side to the size of the image
    • We then set a class of image-replace onto each newly created transparent image
  • We use a 250ms setTimeout to unblock the UI thread and which calls a function resizeImages which enhances the image-replace images so their source is now set to a URL whe

The absurd complexity of server-side rendering

In the olden days, HTML was prepared by the server, and JavaScript was little more than a garnish, considered by some to have a soapy taste.

After a fashion, it was decided that sometimes our HTML is best rendered by JavaScript, running in a user's browser. While some would decry this new-found intimacy, the age of interactivity had begun.

But all was not right in the world. Somewhere along the way, we had slipped. Our pages went uncrawled by Bing, time to first meaningful paint grew faster than npm, and it became clear: something must be done.

And so it was decided that the applications first forged for the browser would also run on the server. We would render our HTML using the same logic on the server and the browser, and reap the advantages of both worlds. In a confusing series of events a name for this approach was agreed upon: Server-side rendering. What could go wrong?

In dark rooms, in hushed tones, we speak of colours.
