How do I configure the worker locally in Wrangler to indicate to Cloudflare that its a Email Worker?

That seems to be for configuring regular Worker to be able to send emails to verified addresses but not for routing incoming emails?

Hello, I’m Allie!OP•10mo ago

It doesn't look like it The config parser only shows options for send_email

I just found in docs:

EmailEvent can be handled in Workers functions written using the ES modules format by adding an email function to your module’s exported handlers:

export default {
  async email(message, env, ctx) {
    message.forward("<YOUR_EMAIL>");
  },
};

Sounds like any Worker can handle emails by adding this parameter

Hello, I’m Allie!OP•10mo ago

Yeah, you can write it in the Worker, but you can't configure which emails are routed to that Worker If that is what you mean

Dovid G•10mo ago

What makes you say it cant be configured for routing?

Hello, I’m Allie!OP•10mo ago

Deciding which addresses are handled by a given Worker can only be done in the dashboard

Dovid G•10mo ago

Why else would you handle EmailEvent?

Hello, I’m Allie!OP•10mo ago

I mean that you can write code to handle incoming emails in a Worker, but to actually use that code, you need to connect some addresses to the Worker via the dash

Thanks, your saying there is no documentation only types? Getting error locally: service core:user:driving-theory: Uncaught Error: No such module "cloudflare-internal:email Presumably the local dev server does not yet support email?

Hello, I’m Allie!OP•10mo ago

Is that at build, or at runtime?

Dovid G•10mo ago

npm run dev from simple Workers template project

Hello, I’m Allie!OP•10mo ago

No I mean when does the error occur when running dev

Dovid G•10mo ago

It occurs on start/build Here is the full error:

✘ [ERROR] service core:user:driving-theory: Uncaught Error: No such module "cloudflare-internal:email".

    imported from "cloudflare:email"


✘ [ERROR] MiniflareCoreError [ERR_RUNTIME_FAILURE]: The Workers runtime failed to start. There is likely additional logging output above.

Hello, I’m Allie!OP•10mo ago

Yeah, gonna guess that it just doesn’t work locally

Dovid G•10mo ago

I can confirm from docs that its not supported: https://github.com/cloudflare/workers-sdk/tree/main/packages/miniflare
