🅽 Why Images Hurt Your App& #39;s Performance and How The New Image Component Can Help - @atcastle

Problem: Oversized Images
Solution: `Image` component that will generate srcset w/ image optimisations

Works w/ 3rd party hosting + auto-formatting
Problem: Too many Images
Solution: Default to Lazy Loading

Escape hatch using `priority` or setting `loading="eager"`
Problem: Loading CSS/JS are prioritised over images
Solution: Preload header for images by setting `priority` on the Image component (https://abs.twimg.com/emoji/v2/... draggable="false" alt="⚠️" title="Warnsignal" aria-label="Emoji: Warnsignal">)

Me: Host images on a different [sub]domain to get around max concurrent limit per host. https://bit.ly/2TuttV0 ">https://bit.ly/2TuttV0&q...
Problem: Content shifts as the images load
Solution: `Image` component will enforce height & width (ratio, no px required).

Opt-out using `unsized` attribute.

You are either network-bound or CPU-bound.

And #JavaScript can hurt you on both of those.
