dave•5/24/23, 5:43 PM

that sounds right, since that uses an S3 backend with buckets in Frankfurt, Ireland, London, Montreal, San Jose, and Virginia.

well, then from austria it should have hit frankfurt

dave•5/24/23, 5:44 PM

if it's <100MB, you can just accept the request data body directly in the Worker and POST it to an endpoint elsewhere without needing to make the client wait.

Ttobi well, then from austria it should have hit frankfurt 😛 😉

dave•5/24/23, 5:45 PM

ah so this crappy S3 provider has terrible uptime, and their Frankfurt server has crazy reliability issues (hours of downtime per month). That's why this Worker is really nice, because it actually checks if the S3 endpoint is working or not.

dave•5/24/23, 5:46 PM

(off-topic but are only using this unreliable S3 provider temporarily mainly because of the lack of per-bucket API tokens for R2.)

dave•5/24/23, 5:47 PM

Will your users be using a browser, or is this going to be used by another backend?

tobiOP•5/24/23, 5:49 PM

mainly browser.

dave•5/24/23, 5:51 PM

we do a lot of preloading on our website. e.g. we have this at the bottom of our head tags:

<link fetchpriority="low" rel="preload" href="/geolocation.json" as="fetch" crossorigin="anonymous" />

<link fetchpriority="low" rel="preload" href="/geolocation.json" as="fetch" crossorigin="anonymous" />

That way when we fetch /geolocation.json/geolocation.json later, it's already loaded.

dave•5/24/23, 5:56 PM

if it's something that could change, then IMO I would do like:

setInterval(() => {
  const link = document.createElement("link");
  link.setAttribute("fetchpriority", "low");
  link.setAttribute("rel", "preload");
  link.setAttribute("href", `/geolocation.json`);
  link.setAttribute("as", "fetch");
  link.setAttribute("crossorigin", "anonymous");
  document.head.appendChild(link);
}, 60000)

setInterval(() => {
  const link = document.createElement("link");
  link.setAttribute("fetchpriority", "low");
  link.setAttribute("rel", "preload");
  link.setAttribute("href", `/geolocation.json`);
  link.setAttribute("as", "fetch");
  link.setAttribute("crossorigin", "anonymous");
  document.head.appendChild(link);
}, 60000)

You should probably remove the old link so you don't end up with hundreds of elements in your header over time

tobiOP•5/24/23, 5:57 PM

hmm, it could change, but you wouldn't expect the user to suddenly change country xD

Peter Belbin•5/24/23, 8:00 PM

hey there folks. question: https://github.com/cloudflare/wrangler-legacy/pull/2221 talks about being able to mark assets for future expiration of cached content to avoid users getting 404 errors when a new deployment happens for Wrangler workers. It also talks about providing something similar for 2.x (and now we're on 3.x). What's the story with this currently (particularly for 3.x). How does KV content get held over until the upgrade is done currently? Really want our users to not see 404 errors because they've been cuaght mid-update.

James•5/24/23, 8:05 PM

I believe in v2/v3 with Workers Sites, old assets are deleted as soon as new ones are published (ref: https://github.com/cloudflare/workers-sdk/blob/4082cfcbdf08740d4a608d3d87df22e51ad0ce4a/packages/wrangler/src/sites.ts#L319). The holistic solution these days would be to migrate to Cloudflare Pages (https://pages.cloudflare.com/) where development efforts are focused instead of Workers Sites

Workers doesn’t have error notifications. You have to put those in your script

dave•5/24/23, 9:11 PM

Correct. It's a bit annoying to have to have different preloading implementations for Chrome vs Safari though. For ease of use, we just stick with doing preloading client side for now.

dave•5/24/23, 9:12 PM

and those are the ones with the slow interwebz who you care about usually

dave•5/24/23, 9:17 PM

@sathoro btw Supabase staff will turn off rate limiting for your project if you ask them and say it's because you're using a Worker. Don't think you were running into issues yet, but figured I should share the info.

Nick Harris•5/24/23, 9:55 PM

Is it possible to use an HTTP proxy server when making outbound fetch calls from a Worker? I have some external services that are IP-restricted, and since CF Worker IPs aren't static I need to proxy it through another server (via tunneling) to make the call.

Nick Harris•5/24/23, 10:03 PM

Ah, gotcha, so you just made requests directly to the nginx reverse proxy?

Nick Harris•5/24/23, 10:04 PM

Thanks, seems like that'll end up being the lightest solution

Walshy•5/24/23, 10:29 PM

looks like you're using JavaScript not TypeScript

Walshy•5/24/23, 10:29 PM

if you remove the typing, it should work

basically just a request to where the client should then upload to. so same thing accomplished, just
