I’m really curious about how Workers with Assets try to match static assets first and then route to a worker if they don’t find a match. Is there an internal worker that handles the routing and matching upfront?

From what I've understood, you can put a worker in front ( all requests uses the worker ) or without worker. All depend of how you setup your wrangler.toml ( « main = './src/index.js' » )
Then, you define in wrangler the folder of your static assets ( « assets = { directory = "./public/" } » )
But, unfortunately, I don't think there is a way to first try to return a static asset and then run the worker. There is a not_found_handler but only to set a SPA ( fallback to the /index.html ) or to set a 404 page

Very soon (in the next few hours) you'll be able to do this. You'll be able to indiscriminately run a user worker (even on a path that would have otherwise matched an asset) and dynamically fetch from the assets binding. Then you could do whatever you wanted to the assets (think, HTMLRewriter) in user worker code

texan•12/3/24, 3:19 PM

Also thanks, Lakano for the issue report, it's being floated around internally

Should preview environments be working with Workers running Static Assets (like a Remix app)? Mine deploys properly, but it's not showing any of the changes

ac•12/3/24, 7:20 PM

In fact, it looks like it's showing super old versions of code. Nothing even remotely close to the actual "live" code (which is deployed via Workers Builds)

does anyone have a working example of using socket.startTls()socket.startTls() to upgrade a socket to be secure? I've followed these docs which for me works with

wrangler dev

wrangler dev

but not wrangler dev --remotewrangler dev --remote. from a worker, I want to connect to an HTTP proxy with the HTTP CONNECT method, then perform TLS handshake, and then GET a resource from a target HTTPS site via the proxy connection

how CPU Time Limit (ms) limit can be set via the wrangler.toml?

I have a weird issue that in two of my projects dependencies dont seem to get installed anymore on deploy. Is that a known issue right now?

alotabits•12/3/24, 11:14 PM

Is there an exhaustive list of compatibility_date changes kept in one searchable place? The workers docs have a recent subset but I need to upgrade from an older date.

Constantin•12/4/24, 1:13 AM

you can see those inside dash

Constantin•12/4/24, 1:14 AM

worker / settings -> runtime (compatibility date)

CConstantin you can see those inside dash

Isaac McFadyen•12/4/24, 1:14 AM

The dash actually pulls from the same source as the docs so if any aren't in the docs they also won't be in the dash unfortunately.

Tom Austin•12/4/24, 2:54 PM

hi all, quick question. I've got a worker that interacts with the cache api however I could still see data being retrieved from the origin when it should be coming from the cache. I've now found that workers without a custom domain have no access to functional cache operations. I've now added a custom domain to my worker. Is my assumption that the issue was the missing custom domain and now that I've added it everything should work correct? Thanks

lucidplot•12/4/24, 3:03 PM

you can see if a request was cached by looking at the response headers

Tom Austin•12/4/24, 3:04 PM

I'm seeing CF-Cache-Status HIT so I guess that's all good then

Shados•12/4/24, 3:18 PM

I can see from the release notes which version of v8 is used by Workerd/Cloudflare Workers. Is there a good resource to tell at a glance what JavaScript features are supported in a given v8 version?

Divanshu Chauhan•12/4/24, 4:07 PM

Hey guys, I don’t if this is the correct place to ask this question but I guess it relates closely to workers hence asking.

I wish to ask for a scenario (hypothetical):

Lets say I have my content in backblaze b2 (around 14tb, mostly photos, videos and zip files). I have around 100-120tb egress per month from b2 to users. How would bandwidth alliance work with this? If I do b2 -> cf worker -> user. What chargers can I expect from cloudflare? I know b2 would charge me for storage and egress between b2 and cloudflare is free because if bandwidth alliance but what about cloudflare -> user?

Is it a bad idea to have a DO that subscribes to a Graphql stream indefinitely? It would be responsible for creating new DOs and broadcasting to them from results in the stream. Running 24/7

Negative•12/4/24, 7:11 PM

Basically proxying this one stream into many dedicated streams.

dave•12/4/24, 7:19 PM

Any ideas on how can use a Worker to pick the "closest" server city? e.g. MiamiMiami is the query, and ["NYC", "Toronto"]["NYC", "Toronto"] is the list of server cities.

dave•12/4/24, 7:20 PM

oh I can use lat/long

Hard@Work•12/4/24, 7:24 PM

It's not a bad idea per-se? You just need some logic to handle reconnections in the event you are disconnected from the stream

rivage•12/4/24, 8:20 PM

It would be awesome if tailing Worker logs streamed logs as they were created, not when requests conclude

rivage•12/4/24, 8:26 PM

Or started steaming logs after walling >15s

rivage•12/4/24, 8:28 PM

Transparency into when queues call consumers would be a welcome addition as well
