go to https://dash.cloudflare.com/?to=/:account/:zone/workers for the domain, and configure the worker routes like this by selecting "None" as the worker for app. and api.:

I'm deciding between using a selfhosted postgres db (where storage space/cost is a non-factor, and its a proper rdbms) vs using cloudflare d1 (scales to 0/no maintenance/no backups needed/etc). Does anyone have any input or experience that may be helpful?

James•12/31/24, 1:15 PM

I’d go with pg + hyperdrive if you want some latency reductions + caching. I can’t safely recommend D1 for production use. https://github.com/cloudflare/cloudflare-docs/issues/18485

yooooo thanks!!

James•12/31/24, 4:03 PM

I'd go with something external like Neon for PG which also has a generous free tier, or Turso for SQLite.

E

Ephemeros•12/31/24, 4:28 PM

I'd also recommend PG, I use supabase but am considering moving to neon (haven't decided yet)

Direct database connections are absolutely possible with workers nowadays

J

James•12/31/24, 4:32 PM

You can use Postgres.js just fine, for example. It uses cloudflare:sockets under the hood

J

James•12/31/24, 4:58 PM

A package needs to be built for it, but there are many common ones that already use

cloudflare:sockets

James•12/31/24, 5:16 PM

I'd drop the

prepare: false

prepare: false

prepare: false

prepare: false these days - hyperdrive is well optimised for prepared statements, but yes exactly. Drizzle + postgres + hyperdrive on Workers is awesome.

E

Ephemeros•12/31/24, 5:25 PM

cool, will try updating that! i had been having some errors with prepare that's why I disabled it before

J

James•12/31/24, 5:26 PM

There were definitely issues some months ago, but that's long since been fixed afaik. I don't use

prepare: false

prepare: false

prepare: false

prepare: false in my stuff and haven't seen any issues yet.

J

James•12/31/24, 9:59 PM

Drizzle can, yes. The example above from Ephemeros is showing exactly that

Isaac McFadyen•1/1/25, 3:21 AM

^ What James said, this was confirmed by an engineer on the Hyperdrive team a few days ago when it came up, so yes, you should be good to use

prepare: true

prepare: true

prepare: true

prepare: true or omit it because it defaults to

true

true

Neon’s serverless driver was useful before Workers could connect to DBs directly. Nowadays I’d recommend just the

postgres

postgres

postgres

postgres library paired with Hyperdrive, and then you can use your ORM library of choice like drizzle or prisms

J

James•1/1/25, 1:51 PM

Don’t bother with the “integrations” in the dashboard

J

James•1/1/25, 3:48 PM

Yep - just

postgres

is it against cloudflare worker terms of service

to have a singnalling server like https://github.com/gfodor/p2pcf and have multiple members of a community host a version on their cloudflare account

the web app will look for one of these cloudflare workers that is active and connect using it

i am afraid it might be abusing the free tier so i had to make sure

J

James•1/1/25, 4:37 PM

I would forego using

@neondatabase/serverless

@neondatabase/serverless

@neondatabase/serverless

@neondatabase/serverless and just use

postgres

postgres

postgres

postgres if you can - it doesn't provide much benefits nowadays.

J

James•1/1/25, 4:37 PM

But generally no, you will not be able to define and connect to the DB outside of your fetch function

J

James•1/1/25, 4:38 PM

A common approach to this is something like a

useDB

useDB

useDB

useDB function that you pass in your

env

env

, and it returns a DB client, and then you can also re-use them across different endpoints, etc. if you're running

hono

hono

hono

hono or some other router where your logic is split into multiple files

J

James•1/1/25, 4:38 PM

Another approach would be to throw it into AsyncLocalStorage, but that's a litle more complex: https://developers.cloudflare.com/workers/runtime-apis/nodejs/asynclocalstorage/

S

Shados•1/2/25, 4:45 AM

Does anyone have any insight on the perf characteristics of workers when you have a larger (a few megabyte) codebase? Since its serverless, how does it get loaded? Do the workers get "prewarmed" and ready to handle their request, or is it just in time (so if there's a lot of javascript to load to serve a single request, your workers are gonna be slow?). Its not obvious to me exactly how they work.

K

kian•1/2/25, 5:28 AM

Prewarmed during TLS handshake, but otherwise loaded upon request and hang around for awhile for other requests till evicted (i.e resources needed for other Workers or runtime update)

https://blog.cloudflare.com/eliminating-cold-starts-with-cloudflare-workers/

The Cloudflare Blog

Eliminating cold starts with Cloudflare Workers

A “cold start” is the time it takes to load and execute a new copy of a serverless function for the first time. It’s a problem that’s both complicated to solve and costly to fix.

i think this is the case, but just asking to confirm: are stack traces only de-obfuscated using the sourcemap for uncaught exceptions? (docs seem to hint at this, but im not certain)

is there a way to get printed stack traces (in a specific structured logging field, for instance) to be remapped back to original line numbers using the uploaded source maps? thanks in advance!

Brett Willis•1/2/25, 9:41 PM

With Tail Workers, is there a way to stream events while the primary Worker's request is still running?
E.g. the request might last many minutes (wall/clock time) so I want to log console messages (to an external service) in a streaming fashion... not just when the request finally finishes 30 minutes later.
