Update prefetch docs with browser support information #8246

bluwy · 2024-05-10T10:17:49Z

Description (required)

Update the prefetch docs based on the core PR linked below, which includes some internal behaviour changes.

I also added a new browser support section to explain the behaviour difference between browsers, and how to ensure prefetching works reliably.

For next Astro patch. See astro PR withastro/astro#10999 (not a minor)

 - If a visitor is using [data saver mode](https://developer.mozilla.org/en-US/docs/Web/API/NetworkInformation/saveData) or has a [slow connection](https://developer.mozilla.org/en-US/docs/Web/API/NetworkInformation/effectiveType), prefetch will fallback to the `tap` strategy.
 - Quickly hovering or scrolling over links will not prefetch them.
- Links that use the `viewport` or `load` strategy are prefetched with a lower priority to avoid clogging up the network.


This will no longer be the case as all strategies will internally use <link rel="prefetch"> which has the same (low) priority.

-You can additionally configure the priority of prefetching by passing the `with` option:
-
-```js
-// Prefetch with `fetch()`, which has a higher priority.
-prefetch('/about', { with: 'fetch' });
-
-// Prefetch with `<link rel="prefetch">`, which has a lower priority
-// and manually scheduled by the browser. (default)
-prefetch('/about', { with: 'link' });
-```


The with option is deprecated so I removed this to discourage people from using it.

Looks great, @bluwy !

I tried something different with the browser support section (haven't seen it in preview yet, so it might be awful). Let's see what we think!

Thanks! I like your suggested formatting too. I committed them and view locally and it looks like this:

Screenshot (Vercel link should also be possible)

Seeing this, maybe we could remove the Support: prefix on each paragraphs? Since the heading "Browser support" already implies so.

sarah11918 · 2024-05-14T15:59:36Z

Yup, agreed! I had it in my head that maybe the different original list items were going to be different, repeatable "things"... but nope, I think without will be just fine!

nit: just seeing now: in the Safari one, there's no comma between "fetch() API which"

bluwy · 2024-05-15T08:08:12Z

Thanks! I've updated and removed them now.

bluwy · 2024-05-15T14:44:22Z

@sarah11918 the core PR has been released. Waiting on your approval just in case and I think we can then merge this

sarah11918 · 2024-05-15T14:58:17Z

@bluwy Thanks, taking one more final pass now, then I'll merge!
