but does work when deployed

i've been using

npx wrangler dev  --remote

npx wrangler dev  --remote

npx wrangler dev  --remote

npx wrangler dev  --remote

which seems to be working

i'm getting two emails now for some reason though. not sure why.

ArmaOP•1/15/24, 6:28 PM

Do you query the endpoint with your browser? if that's the case, maybe it's the favicon request

D

davelongdev•1/15/24, 6:29 PM

i don't think so?

i'm just trying to follow this tutorial https://developers.cloudflare.com/email-routing/email-workers/send-email-workers/

Send emails from Workers · Cloudflare Email Routing docs

You can send an email about your Worker’s activity from your Worker to an email address verified on Email Routing. This is useful for when you want to …

i just deploy the worker from wrangler, start the dev server, and then open a browser window using the dev tools

A

ArmaOP•1/15/24, 6:32 PM

Look at the network tab of your browser, you should see 2 requests. From your description it definitely sounds like the browser is invoking the worker twice

A

ArmaOP•1/15/24, 6:32 PM

which is fine

A

ArmaOP•1/15/24, 6:33 PM

your worker need to check the path that is requested, and not send the email for any random path

D

davelongdev•1/15/24, 6:34 PM

yeah looks like maybe it's the favicon

ArmaOP•1/15/24, 6:37 PM

you would do something like this

A

ArmaOP•1/15/24, 6:38 PM

or better yet, use a router like

itty-router

itty-router

to define your endpoints

davelongdev•1/15/24, 6:39 PM

ok thanks. just learning how to use all of this, so trying to figure it all out.

A

ArmaOP•1/15/24, 6:39 PM

glad to help

A

ArmaOP•1/15/24, 6:41 PM

By the way, you can send a response immediatedly and do the slow email sending in the background

A

ArmaOP•1/15/24, 6:42 PM

by using

context.waitUntil()

context.waitUntil()

context.waitUntil()

context.waitUntil()

I have this code in my email worker:

await fetch("http://example.host.site", {
    method: "POST",
    headers: {
    "Content-Type": "application/json;charset=UTF-8",
    },
    body: JSON.stringify(data),
});

await message.forward("myMainEmail@gmail.com");

await fetch("http://example.host.site", {
    method: "POST",
    headers: {
    "Content-Type": "application/json;charset=UTF-8",
    },
    body: JSON.stringify(data),
});

await message.forward("myMainEmail@gmail.com");

await fetch("http://example.host.site", {
    method: "POST",
    headers: {
    "Content-Type": "application/json;charset=UTF-8",
    },
    body: JSON.stringify(data),
});

await message.forward("myMainEmail@gmail.com");

await fetch("http://example.host.site", {
    method: "POST",
    headers: {
    "Content-Type": "application/json;charset=UTF-8",
    },
    body: JSON.stringify(data),
});

await message.forward("myMainEmail@gmail.com");

When I send email from my gmail i send it to the

myMainEmail@gmail.com

myMainEmail@gmail.com

myMainEmail@gmail.com

myMainEmail@gmail.com but doesnt post the request to the host, but when I trigger email with that test tool, it send the post request. Im new to workers so I dont really know

why is the syntax different in wrangler than in the gui?

K

kian•1/15/24, 11:38 PM

What are you referring to specifically?

D

davelongdev•1/15/24, 11:59 PM

the content of the index.js file in the project folder is different than what shows up in the index.js file in the gui (quick edit) after you deploy it?

D

davelongdev•1/15/24, 11:59 PM

for workers

Wrangler uses esbuild to bundle your Worker, they're functionally equivalent though.

D

davelongdev•1/16/24, 12:08 AM

maybe that's part of it but i'm also seeing two different syntax approaches - service workers and es modules?

K

kian•1/16/24, 12:08 AM

You can do either with Wrangler and the dashboard.

K

kian•1/16/24, 12:08 AM

Service Workers are legacy and use

addEventListener

addEventListener

addEventListener

addEventListener

K

kian•1/16/24, 12:08 AM

Module Workers are the recommended syntax and use

export default

export default

export default

export default

D

davelongdev•1/16/24, 12:09 AM

hrm - i was having an issue using service workers in wrangler so i thought i had to switch it to es modules

D

davelongdev•1/16/24, 12:10 AM

maybe i just had a bug or something ; maybe a cache issue?

D

davelongdev•1/16/24, 12:10 AM

thanks

D

davelongdev•1/16/24, 12:41 AM

i pasted my worker from the dashboard into wrangler and i'm getting a cors error. can't call the worker at all

D

davelongdev•1/16/24, 12:42 AM

maybe i'm missing something idk . ah - i think i need to move the linked kv namespace

D

davelongdev•1/16/24, 1:12 AM

that didn't work :/

D

davelongdev•1/16/24, 1:13 AM

not sure why i'm getting blocked by cors in wrangler but not in dashboard?

davelongdev•1/16/24, 1:22 AM

is this the part that's important? there's a long log file

D

davelongdev•1/16/24, 1:23 AM

key name is empty?

D

davelongdev•1/16/24, 1:23 AM

i'm putting form data in a kv

D

davelongdev•1/16/24, 1:24 AM

ah yeah i didn't fill the form field i guess. thanks !
