I can't say that for certain (green names are only community members), but there is usually a pretty significant delay between a change being merged in workerd and it actually appearing in production. However, they might speed that up seeing as this is a breaking change

Any idea how i can turn my AI response into a valid json? I do not have much experince with ts or even js so i do not know right now

SageSphinx63920•3/7/24, 7:16 PM

JSON.parse(`${response}`);

JSON.parse(`${response}`);

SageSphinx63920•3/7/24, 7:17 PM

This does not work and the reponse is not anything i can put into JSON.parse as it is from type AiTextClassificationOutputAiTextClassificationOutput. Im using distilbert-sst-2-int8

I created an issue about it, it might be purposeful since it's always kind of sucked on mobile/poor experience. Css is hiding it whenever the side bar is hidden, weird that it's gone just now with the rework though

Hey I wanted to setup billing notifications when my workers hit a limit - number of requests or CPU time, but the billable usage notifications only allow me to select the old pricing (unbound/bundled) requests and I use the standard pricing. Is there a way to setup notifications for standard?

I have never used Cache in Workers (new to workers overall), but could it be used to create a very basic rate limiter? I'm basically thinking of protecting routes that query my D1 Database and reduce usage.

Isaac McFadyen•3/8/24, 3:14 PM

Rate limiting = no, not really? Cache can be used to protect your origin, yes, but the Worker will still be invoked since Workers run in front of cache, and there's not really a "limit" just more of a protection.

Isaac McFadyen•3/8/24, 3:14 PM

Rate limiting is usually defined as actually blocking some traffic when it exceeds a rate, whereas caching is just protecting your origin.

I am serving a single htmlhtml page that has different values in the

head

head

depending on the path, im wondering if there's a good way to organize my code so i can work on html separately

ftqo•3/8/24, 3:15 PM

putting it in a string is a bit annoying to work with

Isaac McFadyen•3/8/24, 3:16 PM

Have you tried Cloudflare Pages? You can serve static HTML there and then also use Functions to have dynamic behavior (functions are basically workers that run on specific paths).

ftqo•3/8/24, 3:16 PM

i was looking into that but couldnt find a way to modify the page based on path

Fftqo i was looking into that but couldnt find a way to modify the page based on path

Isaac McFadyen•3/8/24, 3:17 PM

So you'd put a static HTML page up and then set up a Function for each path that modifies the <head> in different ways.

Isaac McFadyen•3/8/24, 3:17 PM

Or you can have a single, monolithic function that just does the path-matching code by itself rather than using the Pages router.

ftqo•3/8/24, 3:19 PM

export const onRequestGet: PagesFunction = async (context) => {
  const path = new URL(context.request.url).pathname;
  return context.env.ASSETS.fetch(context.request);
};

export const onRequestGet: PagesFunction = async (context) => {
  const path = new URL(context.request.url).pathname;
  return context.env.ASSETS.fetch(context.request);
};

ftqo•3/8/24, 3:20 PM

instead of returning, id modify that response?

ftqo•3/8/24, 3:24 PM

im not sure how else id do it

Isaac McFadyen•3/8/24, 3:26 PM

Yeah exactly. You'd want to do

const res = context.env.ASSETS.fetch

const res = context.env.ASSETS.fetch

and then do a

const text = await res.text()

const text = await res.text()

and then modify it and return it.

Isaac McFadyen•3/8/24, 3:26 PM

And then have a separate Function on each route for different modifications.

Isaac McFadyen•3/8/24, 3:27 PM

Or actually you could use HTMLRewriter, would be faster and more efficient: https://developers.cloudflare.com/workers/runtime-apis/html-rewriter/

Simple example: lets say that i have an api endpoint that makes many queries to my database. i want to limit the endpoint usage by ip to like 10 hits in 10 seconds. I want to limit this to minimize the reads/writes my database does. Would i be able to create a middleware in front of the endpoint that checks the remaining queries for the specific ip? I understand that my worker would still be invoked, but could this be used to prevent querying my database in such cases?

am i accessing the env variable wrong here? when i log the env variable being passed by fetch this is what i get, the route path and other stuff

Isaac McFadyen•3/8/24, 5:02 PM

You could yes.

Isaac McFadyen•3/8/24, 5:02 PM

Or you could use a Cloudflare Rate Limiting rule which I believe is applied before the Worker.

Isaac McFadyen•3/8/24, 6:27 PM

Pages doesn't take the same inputs as a Worker.

See here: https://developers.cloudflare.com/pages/functions/api-reference/#eventcontext

IIsaac McFadyen Pages doesn't take the same inputs as a Worker.

cora•3/8/24, 6:52 PM

so do i have to use a pages function instead? because that seems to give the same error

Isaac McFadyen•3/8/24, 6:56 PM

You can use a Worker or Pages, but if you're using Pages you should be using a Function. What error are you getting exactly?

I might be missing something here, does npx wrangler pages dev .vercel/output/static automatically turn pages/api routes into pages functions for cloudflare? So I don't have to change them into edge functions?

How do I call the fetch on service A without having to manually specify the URL as it might change

When using the service binding the URL doesn't really "mean" anything in the normal fetch sense here, it just is passed verbatim to the other Worker in

request.url

request.url

. It will still hit that worker even if you put something silly like

http://dummy

http://dummy

how can I stop external requests from being able to hit project A directly?

Disable the workers.dev subdomain for the Worker (

workers_dev = false

workers_dev = false

in wrangler.toml) and don't define any

routes

routes

entries for it.

Hello, I’m Allie!•3/8/24, 9:09 PM

IIRC you do have to mark them as edge functions, then they should be built into Pages Functions automatically

cora•3/8/24, 9:11 PM

Interesting - so this was my old route, it was fine as is?

cora•3/8/24, 9:13 PM

I changed it to this manually

Ccora Interesting - so this was my old route, it was fine as is?

Also this doesn't make sense to me, how would you access the env if you kept the api route the same
