Cloudflare Worker Example

[iosdeveloper]

Running OS

macOS 13.5.2

Running Node Version

16.19.1

Description

Trying to run examples/cloudflare-worker/webpack5.x using npm run example fails.

Expected behavior

Local server successfully starts

Steps to reproduce

Execute npm run example:

> cloudflare-worker@0.0.0 example
> npx wrangler dev --ip 0.0.0.0

 ⛅️ wrangler 3.10.0
-------------------
wrangler dev now uses local mode by default, powered by 🔥 Miniflare and 👷 workerd.
To run an edge preview session for your Worker, use wrangler dev --remote
▲ [WARNING] Processing wrangler.toml configuration:

    - 😶 Ignored: "type":
      Most common features now work out of the box with wrangler, including modules, jsx,
  typescript, etc. If you need anything more, use a custom build.
    - Deprecation: "zone_id":
      This is unnecessary since we can deduce this from routes directly.
    - The "route" field in your configuration is an empty string and will be ignored.
      Please remove the "route" field from your configuration.
    - Deprecation: "build.upload.format":
      The format is inferred automatically from the code.

Running custom build: npm run build

> cloudflare-worker@0.0.0 build
> npx webpack --config webpack.config.mjs

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

Were you able to verify it by using (and changing) the examples?

Yes

If yes, which changes did you apply?

Fix missing entry-point error by adding this line to wrangler.toml:

main = "dist/worker.js"

Since this example is quite old, is there a better way to install this project in Cloudflare Worker?

Hey @iosdeveloper, thanks for using passkit-generator!
Well, I guess something might have changed. I'll take a look and update it.
Thanks for your pointer!

I honestly don't know. I do not work with Cloudflare Workers. I barely used them to create the example when a guy shared their existence with me.

I'll keep you posted about this.

Hi @iosdeveloper, 34a12e3 brings the new reworked cloudflare workers example.

I've removed the two examples there were before as they were completely outdated as you found out. I'd like to thank for reporting me this.

I've been able to run the worker locally without any issue, but I haven't tested a deployed version.

Let me know what do you think of this!

P.s. if you could leave a ⭐ on the project, that would be awesome!

[iosdeveloper]

It works! Thank you so much. 💙

[iosdeveloper]

Already did 😃
