Priority Hints is rolling out to Chrome in the 101 release which is currently available in the Dev/Beta channel of Chrome and available in WebPageTest when using the Chrome Canary browser selection.

To make it easier to experiment with priority hints (particularly for LCP images) without making production changes, I set up a couple of public Cloudflare Workers that can be used dynamically with WebPageTest to inject priority hints into existing pages and to preload arbitrary images when combined with WebPageTest's overrideHost script command.

Injecting Priority Hints

There is a cloudflare worker at hint.perf.workers.dev that will take a CSS selector from the x-hint HTTP header and add fetchpriority=high to any elements in the HTML that match the selector.

// I did this in Chrome...

// Go to https://www.facebook.com/ads/preferences/
// Click the "Advertisers" section to open it up.
// Click "See more" once
// Before doing anything else, just keep clicking space bar to trigger the "see more" button
// Do this for a bit until all the advertisers are loaded
// then run this below in the dev tools console...
// (It will take a few minutes, depending how many you have, and your browser may lock up, but once it's done you will see it auto clicked the "remove" X in the top right for all of them)
