Hey guys, I have a question regarding Cloudflare's cache API. I'm developing some features that will use the cache API a lot and I came across a rather curious situation:

I wanted to create several caches with different keys but I would like to use tags as well because even though each cache has an ID I wanted to have something (which in this case would be using a tag for this) to have a relationship. For example, imagine that I have a cache for a user with ID 50.
I create a cache with this user's information but I would like to put a tag on this cache that says "user" to identify what this cache represents.

When I perform a delete action I would like to use the tag to delete all caches with the "user" tag, thus deleting all related caches. Is this possible through the Cache API using Workers? Because today I only work with different keys from one to another and this has caused me problems in relation to these cases.

I am an Enterprise customer so I have access to several resources available from Cloudflare but I don't know specifically how to do this.

Like this?

// Only default cache can be purged via API
const cache = caches.default;

await cache.put(`https://fake.host/${userId}`, Response.json(userData, {
  headers: {
    "cache-tag": "user"
    // Other headers
  }
}));

// Only default cache can be purged via API
const cache = caches.default;

await cache.put(`https://fake.host/${userId}`, Response.json(userData, {

}));

yes, but I would like to know if the delete function of the cache api (https://developers.cloudflare.com/workers/runtime-apis/cache/) would work if I only passed the cache-tag to delete. Is this possible or would this deletion by tags be directly through my cloudflare panel or only via the cloudflare API.

I just recorded a video on how to use Workers AI which will be included into my GenAI Essentials free course. I would have conitued on with Vectorize and the other AI services but I had too much friction with Vectorize and had to move on.

Hi all, any idea for what would be more relevant for Session Management (authenticated users sessions storage) between D1 and KV? Specifically, would KV provide better latency than D1, and is the eventual consistency of KV fine for this use case?

All opinions are welcome !

I believe Cache Tag purging must be done via the HTTP API

Are there any plans to support multiple primary workers with different ports, to expose their fetch handlers, when using wrangler with multiple config files?

alex (he/him)•12/21/24, 9:07 AM

Is there any way to set a service binding to a specific version. Preview URLs allow us to access a specific version by URL, but it would be amazing if we can set a service binding to a specific version. Thinking about connecting all staging versions together to get a fullstack preview of a PR

H4x0rus•12/22/24, 2:45 AM

I'm not sure who would be responsible for this, but workers currently can't install using npm with the legacy peer deps flag in the auto deploment. With react 19 rolling out I could imagine that this might be a big issue for many projects.

hi all, wanna ask, when building a websocket with durable object hibernation api.
does it possible to do service binding from Pages to the Workers? without harcoding / configuring the websocket server path in Pages? (like ws://example.com or wss://example.com)

Thanks in advances!

CCoshmar Tabletowy V you mean programatically?

Omar Abid•12/24/24, 4:15 AM

I mean something like baselime but that does actually work and has low latency.

depends

Walshy•12/24/24, 9:20 AM

If you are invoking the Worker for each asset and you had like 50 assets, that's only 2,000 page views

Walshy•12/24/24, 9:20 AM

But also, lots of bots will come when a new Worker/domain is published to see if they can find any vulnerabilities

it's a completely empty next js build with like one page, also i deployed exact same way another worker just before this one and it has only 100 requests, that last one over night got botted i guess

NZX•12/24/24, 9:24 AM

is there a way to prevent bots then ?

Walshy•12/24/24, 9:26 AM

Not really sadly, it's just part of the Internet. Whenever a new cert is created, bots will instantly start hitting it

Actually, I was deploying my next.js project(with dynamic routes) into cloudflare pages.
I searched the solutions for the dynamic routes, I couldn't any solution and detailed guide.
That's why I try with the cloudflare worker Beta.

TDA•12/24/24, 6:52 PM

I still wanna know if it is possible to deploy the next.js project which include dynamic routes into Cloudflare Pages
