Argo does optimize the connection to origins though, that's sort of the main point whereas the ingress optimization is kind of just another benefit. Fetch within worker should also benefit from that

ChaikaOP•10/30/25, 4:48 PM

Fetching content is one of the most common Worker tasks. fetch() has always leveraged powerful Cloudflare features like Argo and Load Balancing.

Thanks for the response! Good to know, I’m glad you get that backbone for “free” :)

Sorry unrelated but

d1, r2 are durable objects

D1 I knew, but r2? That’s really cool

Hi 2 all
What is the best solution for storing audit logs for customers(organizations) from Workers+DO ?

trololo•10/31/25, 7:20 AM

my use case is writing logs for customers for critical (and not only) actions with their data in my web apps. Then customers could see this logs (at least last 3m) or download for 7 years

1984 Ford Laser•10/31/25, 7:52 AM

What sort of scale are you thinking? You could use Workers Analytics Engine to store the data then export it as files per 30 days or something in R2 for longer term archive. I think WAE is the cheapest way to write logs on platform

trololo•10/31/25, 8:10 AM

Oh thank you. I've thought about this solution, but maybe there is another way

Scaling - like 2-3 web apps, but want to make it scalable from the start. WAE is better and free(included in workers paid) from the start. On R2 will store aggregated data each hour (with scale will be more frequently)

1984 Ford Laser•10/31/25, 8:12 AM

How many events per hour are you thinking of storing? On average

We are trying to setup a 24/7 realtime dashboard with workers that receive ~5 messages per minute. Does anyone have cost estimates using websockets? We are considering using SSE for reduced costs. Does that make a difference?

dave•10/31/25, 4:54 PM

IMO use any S3 API provider you like, and https://github.com/mhart/aws4fetch in your Worker. Backblaze B2 would be my suggestion. It's $0.006/GB, or $0.012/GB if you want to do high availability by mirroring two buckets in different regions.

https://gist.github.com/Manouchehri/733e6235457e60de24fdbb15046fba7f

Add a lifecycle policy to the bucket that deletes files after 7 years.

Put each customer's files into like s3_bucket_name/customer_id_here/2025/10/31/23/epoch_time_here_uuid-of-event-here.jsons3_bucket_name/customer_id_here/2025/10/31/23/epoch_time_here_uuid-of-event-here.json. Then, when a customer wants say, the last two days of logs, you can do a ListObjectsV2 request to s3_bucket_name/customer_id_here/2025/10/30/s3_bucket_name/customer_id_here/2025/10/30/ and s3_bucket_name/customer_id_here/2025/10/31/s3_bucket_name/customer_id_here/2025/10/31/ to get all the JSON files of their events, which you can then use aws4fetch again to give the user presigned S3 URLs to download their events.

dave•10/31/25, 4:57 PM

Backblaze B2 also doesn't charge for uploading objects, so it's fine if you're uploading millions of small files to the same bucket. https://www.backblaze.com/cloud-storage/transaction-pricing

dave•10/31/25, 4:58 PM

And lastly, definitely use gzip for compressing JSON events! The user's browser (or the Worker) will automatically decompress it as long as you set the content-encoding: gzipcontent-encoding: gzip when uploading.

geg•10/31/25, 7:51 PM

Am I correct to assume that MessageChannel API is safe way to send events between different requests the worker is handling? For example letting 2 websocket clients that hit the same worker isolate talk to eachother is now possible? I kind of did something like this before but by polling a global value

(circumventing the "Cannot perform I/O on behalf of a different request." error)

Keep in mind that there is absolutely 0 guarantees you'll hit the same datacenter or even that there won't be multiple copies of a Worker running in a datacenter.

1984 Ford Laser•11/4/25, 1:17 AM

What are people's email sending service of choice to use with Workers? I know the closed beta of the new email product is coming this month, but don't wanna wait around too long for access. I will be sending around 100 emails a week, and the addresses will always be from the same set of users more or less (would prefer to not need a manual confirmation from users to be allowed to accept email from service). No plans to scale higher, so something with a free tier or something is best. The content will be a templated HTML or something similar depending what the service requires

Would it be against ToS to ingest a video stream (fMP4) from Stream using a DO and something like mp4box, then send the video frames as bytes over WebSockets to listening clients and then the clients re-create the streams using Media Source Extensions?

Asutosh Panda•11/4/25, 2:15 PM

hey folks, new to the cf platform
have deployed a few static sites on the pages
but now when I tried to deploy something more, getting a bunch of errors
the app is in nextjs, fetches real estate info from a google sheet

so far tried to use edge runtime, nothing was on the depoyed URL
api routes work fine in local but becomes messy when I use functions, nothing loads on the app

used this guide - https://developers.cloudflare.com/workers/framework-guides/web-apps/nextjs/#deploy-an-existing-nextjs-project-on-workers
no luck with this as well, have been trying in local, the preview or run dev commands dont bring up the app in the respeactive port
shared the screenshot with project structure and errors as well

what else is missing or going wrong here, can anyone please help out to make this work with wrangler locally, then I will jump to the deployed one
please let me know what else do I need to share to give more context
