What generator do you folks recommend for creating TypeScript bindings from an openapi.jsonopenapi.json file? I tried this one but I get duplicate identifier errors. https://openapi-generator.tech/docs/generators/typescript/

I was able to get this one working, but it annoyingly does not create any documentation. https://openapi-generator.tech/docs/generators/typescript-fetch/

You can do it via the CF API

hey i get that error

"outcome": "exception",
  "scriptName": "api",
  "exceptions": [
    {
      "name": "Error",
      "message": "Promise will never complete.",
      "timestamp": 1684010032023
    }
  ],

"outcome": "exception",
  "scriptName": "api",
  "exceptions": [
    {
      "name": "Error",
      "message": "Promise will never complete.",
      "timestamp": 1684010032023
    }
  ],

My script handles files that got uploaded to the worker, but i only get that if the file is above .fex 50mb if its below it works just fine

why does it say it "Promise will never complete."

@sathoro btw here's a reply from Supabase about Workers getting rate limited that might be useful for you in the future.

Hi David,

Really appreciate the detailed reply here!

We've discussed this internally and it looks like we'll be going with this approach:

> Another possible simple idea, is to only bypass rate limiting for a new “no limit anon key”.

This will probably take some time to roll out since we have some other on-going tasks. I guess the temporary workaround you have helps for now and we'll definitely let you know once we've implemented the proper fix.

are you using anon keys or service role?

Ssathoro are you using anon keys or service role?

dave•5/14/23, 4:51 AM

Both. I know it might seem a little funky since it's all server (Worker) side stuff , but I prefer using the anon key when possible to make it harder to shoot ourselves in the foot when it comes to access controls.

the service key having rate limiting does seem odd to me, but tbh we're very new to supabase so there's probably use-cases we're totally unaware of

can anybody recommend a good logging system for production that will easily allow for filtering errors? I know about Logpush - I'm wondering what I should push to

sathoro

S

sathoro•5/14/23, 8:03 AM

also, we have been pushing to R2 but not doing anything with the logs... if there is a solution for seeing logs inside R2 that would work too

We use a tool called axiom (https://axiom.co), they have a built-in integration for worker logs, and they're also working on a logpush endpoint for ingest. Their free tier goes up to something like 500GB a month axiomspin

It looks like laravel is PHP, so no, not really. If you really want to you might be able to get it working with WASM though

can i do let my worker run for 5 minutes f.ex with "waitUntil" and a promise timeout that resolve after 5 minutes or 4 minutes? (currently i have free plan if that is important), after that 5 minutes it would fetch something and send response

Cloudflare is looking at releasing TCP Workers very soon, allowing users to connect to any TCP service using Workers.

This can include things like databases, such as in this example. It's going to be super exciting to see what everyone builds with this!

The native API is…

Even when Workers eventually support raw TCP communication, we will not have fully solved our problem, because database connections are expensive to set up and also have quite a bit of memory overhead.

not fully solved though at least not without building a lot of connection pool logic. for example you don't want only a single connection, you would want multiple and you also would want a different number of db connections and client connections, etc. and this is just the tip of iceberg

sathoro•5/14/23, 7:43 PM

1 single connection? I dunno... it would work fine until very suddenly it doesn't and then you'd be asking yourself why you didn't just setup a proper connection pooler while your app is down in production and you are scrambling

AA•5/14/23, 7:43 PM

pgbounce sounds better

do you already have a postgres db? because one option is to use Supabase. you get a dedicated Postgres db and can use their HTTP APIs (this is what we do)

sathoro

S

sathoro•5/14/23, 7:47 PM

we try to call Supabase directly from the client (browser) as much as possible but in a couple situations we call it from in a Worker and it is easy to do

another option is putting PostgREST in front of your db

yea i saw some cloudflare docs recommending that as well

sathoro

S

sathoro•5/14/23, 7:49 PM

actually I think Supabase uses this

sathoro

S

sathoro•5/14/23, 7:49 PM

it has built in connection pooler

sathoro

S

sathoro•5/14/23, 7:50 PM

so might as well do that since you'd have to setup a connection pooler anyways...
