No. But neither does the code in examples of the blog.

Does your

include a route/workers.dev?

Hello, I’m Allie!•5/8/24, 9:10 PM

The example on the blog appears to be for a Worker that can only be called via Service Bindings, so it shouldn't have any routes/crons/queues, etc.

name = "worker-t"
main = "src/worker.js"
compatibility_date = "2024-05-07"
node_compat = true

Try adding

IIRC it adds

by default, unless you add a route

@HardlyWorkin' It appears to have worked. The binding found worker and called the method. I made a mistake in my code, but that will be quickly fixed.

Steven•5/8/24, 9:56 PM

Hi all, I have a quick questions, I currently have a Worker that is responsible for putting json's in KV that will be read from a Cloudflare pages project. The idea is to prepopulate the cache in order to get super fast pages. At the moment I created a worker that runs fine locally and can add a few thousand entries into my local wrangler state. However after deploying the worker I hit the limit of 50 subrequests. I think I can rewrite the worker to use a queue and split up the work, thus reducing the number of subrequests. But I'm wondering what the best approach is for my use case?

[vars]
dotenv = ".env"

in wrangler.toml how do import the vars for the cloudflare worker to use from my own .env file? currently it seems cloudflare is interpreting dotenv as its own variable rather than importing the variables

All that does is set

to be a string of

Barry_Based_Benson•5/9/24, 3:20 PM

ok so i set up a .dev.vars file with my env variables and then deployed the worker but i still don't see it showing up on the cloudflare dashboard, nor is my worker using it. Am i misunderstanding how it's meant to be used?

export interface Env {
    BUCKET_URL_AUTH_GENERATION_KEY: string;
    BUCKET_URL_SYMMETRIC_KEY: string;
}

export default {
    async fetch(request: Request, env: Env,): Promise<Response> {
        if (!env.BUCKET_URL_AUTH_GENERATION_KEY || !env.BUCKET_URL_SYMMETRIC_KEY) {
            return new Response("Missing required environment variables", { status: 500 });
        }

export interface Env {
    BUCKET_URL_AUTH_GENERATION_KEY: string;
    BUCKET_URL_SYMMETRIC_KEY: string;
}

export default {

            return new Response("Missing required environment variables", { status: 500 });
        }

am i supposed to somehow use them here? how? do i change the param name or something?
