Hello CF community! I have a project where I'm using react with Pages, and I would like to use Supab

Hello CF community! I have a project where I'm using react with Pages, and I would like to use Supabase Auth, and I have some questions. Tbh, I don't know from where to start (beginner alert

). The integration of Workers include Supabase Auth? If so, should I use it in my project to auth users, or I can just stick to the client-side from react? Also, is there anyone who tried and made this work who eventually has some repo as a reference? Thanks a lot in advance.

I think it'd be easier to stick with clientside

zach•3/29/24, 4:37 AM

with a worker in the middle, you gotta handle frontend <-> worker <-> supa errors

zach•3/29/24, 4:37 AM

i think if you have properly scoped access tokens for supa, you'll be chill to use it on the clientside

zach•3/29/24, 4:38 AM

that said, I've never been happy with letting untrusted internet interface directly with my db

does cloudflare loadbalacner have concurrent connectino limits ?

vimo•3/29/24, 11:23 AM

Is there a way to pause the quick reload of the workers playground? or add a delay to its reload?

K•3/29/24, 11:54 AM

There is an issues with concurrent fetches and queing. Its described and posted with workaround here workers-and-pages-helpSimultaneous fetches over 6 are being dropped instead of being queued.

I don't know whom to ping for this (which channel) so I'll leave it here.

Workers aren't Nodejs, they have some node compat but not full, iirc googleapis uses a ton of node apis including their own version of axios, would have to change it pretty majorly

Hello , i have a question regarding caching through fetch API : https://developers.cloudflare.com/workers/examples/cache-using-fetch/
let's say i have a worker that i want to fetch data from and cache this data for an hour so that the next request the data should be taken from the cache.
So i am expecting for the same request with in my window of an hr, the 2nd fetch response would be taken from the cache not go to make another http request correct ?
if this is the case why for every fetch request i do the worker gets called and returns the response?
How can i validate that this is from the cache or not?
i have set

cf: {
        cacheTtl: 3600,
        cacheEverything: true,
      },

cf: {
        cacheTtl: 3600,
        cacheEverything: true,
      },

in my fetch request.
is there somethig i should add ?

Cache by default is per colo/cf dc, and some Cloudflare Points of Presence even have multiple colos, so you might be routed to a different one/different visitors will certainly be, and get MISS's, plus TTL is just a max and CF may evict it far before then based on access frequency.

if this is the case why for every fetch request i do the worker gets called and returns the response?

The worker will always be invocation/run on every request, even if using cache

How can i validate that this is from the cache or not?

Check response headers for CF-Cache-Status

Isaac McFadyen•3/29/24, 3:39 PM

IIRC they also use gRPC which isn't supported even with polyfills

Isaac McFadyen•3/29/24, 3:39 PM

Or at least a lot of them do

Isaac McFadyen•3/29/24, 3:39 PM

Or maybe that's just GCP's?

Razzmatazz•3/29/24, 5:00 PM

Anyone know why purging by URL via a fetch request to the API (https://api.cloudflare.com/client/v4/zones/[zone]/purge_cache) done via a worker apparently is ignored? The API response indicates success, but the cache is definitely not purged.

A longer explanation is that cloudflare workers are meant to run bits of code and then terminate. A discord bot needs to continue running indefinitely.

Hello, I’m Allie!•3/30/24, 10:36 AM

Well, that’s not entirely the case. It is more that Discord has blocked Worker’s IPs from connecting to the Gateway

Hello, I’m Allie!•3/30/24, 10:37 AM

You could build a Gateway Bot with Durable Objects. It wouldn’t be quite as ergonomic as one built in Node, but it definitely is doable

Hello, I’m Allie!•3/30/24, 10:37 AM

How many independently-disqualifying reasons do you need for why it's not feasible to use discord.js to make a discord bot in a worker?

added cors to my cf-worker but everybody can still access my endpoint:

        .merge(mount())

CORS does not prevent those that don't respect CORS from hitting your Worker, if that is what you mean

Hello, I’m Allie!•3/30/24, 1:32 PM

It only works for stuff like Browsers

vloe•3/30/24, 1:38 PM

Hello, I’m Allie!•3/30/24, 1:39 PM

You can check certain headers to see if they match, but if the attackers are persistent, there isn't much you can do

Hello, I’m Allie!•3/30/24, 1:40 PM

There isn't a 100% foolproof way to ensure that a request is only coming from your app(unless you control the client, and don't allow anyone access to it)

vloe•3/30/24, 1:46 PM

i see, thank you!

Is there a knack to getting service bindings working locally? I have two running locally, both using

npm run dev

npm run dev

and worker A is bound to worker B. Worker B calls Worker A, and when I start Worker B I get:

⛅️ wrangler 3.41.0
-------------------
▲ [WARNING] This worker is bound to live services: AUTH (authentication-worker)


Your worker has access to the following bindings:
- Services:
  - AUTH: authentication-worker
▲ [WARNING] ⎔ Support for service bindings in local mode is experimental and may change.

Your worker has access to the following bindings:
- Services:
  - AUTH: authentication-worker
▲ [WARNING] ⎔ Support for service bindings in local mode is experimental and may change.

The warning itself is a little confusing, as it's running locally, so I don't know why it's mentioning live. Either way, when I hit it with a request, I get

Cannot read properties of undefined (reading 'fetch')

Cannot read properties of undefined (reading 'fetch')

if I run Worker B in remote mode, it works fine (but presumably hits my live worker), so I'm quite confused. Any ideas?

Okay I just read https://github.com/cloudflare/workers-sdk/issues/1182, in which case https://developers.cloudflare.com/workers/configuration/bindings/about-service-bindings/#local-development is highly misleading
