Could someone please enlighten me about the latest and hottest frameworks for building JSON APIs on Cloudflare Workers? Haven't been keeping up with the latest libraries for a while.

Hono

kian•2/28/23, 2:03 PM

Yeah, probably Hono haha

aspOP•2/28/23, 2:04 PM

Is it just objectively the best framework at the moment?

kian•2/28/23, 2:05 PM

Lots of cool middleware - CORS, Sentry, loggers, Zod validation, etc

aspOP•2/28/23, 2:06 PM

Alright, thanks

I use itty-router-openapi for some things, Hono for others. https://github.com/cloudflare/itty-router-openapi

itty-router-openapi does have some limitations that are a bit annoying tbh.

kian•2/28/23, 2:52 PM

I suspect you'd need to be on an Enterprise plan for such a limit increase but you can always request one at https://docs.google.com/forms/d/e/1FAIpQLSd_fwAVOboH9SlutMonzbhCxuuuOmiU1L_I5O2CFbXf_XXMRg/viewform

dave•2/28/23, 2:58 PM

Could you split the app into ~3-4 different scripts, and have them use service bindings?

Unsmart•2/28/23, 3:31 PM

If only remix had hybrid outputs because I assume there are pages that are fully static that could easily be removed from the worker script entirely and run on pages

Unsmart•2/28/23, 3:51 PM

I feel like that goes way too far for cloudflare

would be better to have hybrid output than 50 server exports

TTom Sherman it's just a shame that remix has a monolithic approach, which makes things diffi...

Hello, I’m Allie!•2/28/23, 3:54 PM

I mean, Workers do perform measurably better in a monolith structure, rather than as nanoservices(as evidenced by Service Binding cold starts).

Hello, I’m Allie!•2/28/23, 3:55 PM

That's what I mean. Once a script is warm, it is warm. If you have to dive into a service binding, then you are subject to a second/third/fourth set of cold starts.

Hello, I’m Allie!•2/28/23, 3:55 PM

If your script is a monolith, you only cold start once.

kian•2/28/23, 3:56 PM

now I want to benchmark svc binding startup

Unsmart•2/28/23, 3:56 PM

Another issue with that approach is eventually you hit the limit of workers granted it is pretty large

and deployment when you have many workers is much harder because cloudflare doesnt have targetable versions like AWS does on lambda so you might get in a weird state where some workers are updated and others arent

Hello, I’m Allie!•2/28/23, 3:56 PM

Like, break a script up when it gets too large, but until then, try to keep it in as few as possible.

kian•2/28/23, 3:56 PM

service environments would fix that when they come back

kian•2/28/23, 3:56 PM

w.r.e targetable

kian•2/28/23, 3:56 PM

but... I have no idea when they'll come back

kian•2/28/23, 3:57 PM

I kinda miss them already

Unsmart•2/28/23, 3:57 PM

If service environments do fix that it would be nice yeah but not here rn

kian•2/28/23, 3:57 PM

more specific to this scenario, service bindings can target a specific service environment on the bound worker

kian•2/28/23, 3:58 PM

but i don't know if the API validates that at publish time

kian•2/28/23, 3:58 PM

i.e can you depend on Worker A Env A in Worker B Env A if Worker B is published before Worker A?

kian•2/28/23, 3:58 PM

probably not

Unsmart•2/28/23, 3:58 PM

Im talking about not only targeting a specific environment but a very specific deploy version inside the env

Unsmart•2/28/23, 3:59 PM

environments for CF im pretty sure is more dev staging prod not for blue/green

Unsmart•2/28/23, 3:59 PM

but not sure as I never used them

Unsmart•2/28/23, 3:59 PM

Maybe you could create a new environment for every different deploy and retarget but that is a lot

aspOP•2/28/23, 3:59 PM

You could use WfP to target a specific version.

Unsmart•2/28/23, 4:00 PM

if you have WfP you could but that also adds more to cold starts

Unsmart•2/28/23, 4:01 PM

the whole point of the github issue you linked said cold starts to be fair

kian•2/28/23, 4:02 PM

time to benchmark svc binding cold starts

dave•2/28/23, 4:05 PM

for each worker, I end up with at least 2 versions of it, sometimes three. (dev, staging, and production)

kian•2/28/23, 4:06 PM

sub 15ms

kian•2/28/23, 4:08 PM

we currently appear to have some workers publish lag
