Whenever I run dev, the process oftentimes doesn't shut down correctly and it ends up needing to use a different port every time. I get errors like this: ✘ [ERROR] Address already in use (127.0.0.1:60392). Please check that you are not already running a server on this address or specify a different port with --port. So I have to run the following:
lsof -i :60392
kill -9 <PID>
lsof -i :60392
kill -9 <PID>
Is there a way to avoid this or fix this? I feel like this is some known issue. When I searched about it online, I think folks are saying it's due to the hot-reloading feature, but this seems like a fundamental issue.

👋 Trying to figure out how to set up my local directory structure for a project with Pages and Workers which need to access D1. Seems like wrangler gnerally expects to be in the same directory as the pages/worker project. Anybody know of examples of a multi-component project like this?
project
- pages_dir
- src/
...
- worker1
...
- wranger.toml
project
- pages_dir
- src/
...
- worker1
...
- wranger.toml
I currently have separate the worker and pages projects in separate directories with their own wrangler.toml, but need to duplicate my D1 schema in both and I think they would have different local DBs when running locally. Hoping there's a better way to have everything together. 🤞
Hello, I’m Allie!
You can use —persist-to so they point to the same directory when storing data Then db instances will be shared

hey hello, i am facing "ERR_RUNTIME_FAILURE": MiniflareCoreError [ERR_RUNTIME_FAILURE]: The Workers runtime failed to start. when i execute the "npm run dev" command in my Cloudflare web app - I created this app using "npm create-cloudflare" (v 2.21.9), wrangler (3.62.0) - web app - framework Honojs - no git, no deploy now when I execute the command "npm run dev" it the gives above error and the development server won't start i tried executing "wrangler dev" directly (with version < 3.62.0) it runs the application but i don't know whats wrong with create-cloudflare

so i tried using cf wrangler + devtools to profile my js but i only get (program) as the profiled code and it runs for the whole duration so it's not very useful and it happens also when using chrome://inspect and connecting using the new Performance tab (though i had to pass the --inspect flag to wrangler to make it connect properly) and when i use the example from the web it just gives (program) as well

no, I'm trying to run wrangler locally and it's getting an error, I just did exactly like the documentation says to start a project "npm create hono@latest" but when I run "npm run dev" I get this error MiniflareCoreError [ERR_RUNTIME_FAILURE]: The Workers runtime failed to start. There is likely additional logging output above. from this my-app\node_modules\wrangler\wrangler-dist\cli.js:29747 throw a; ^ and searching on google and in this community I found may be the wrangler needs certification to run locally

Also unable to run pages (remix framework created with create-cloudflare) with wrangler locally (not sure why it thinks the address in use - it's not)

Hello, I’m Allie!
That sounds like something else… Did you try again?

yes, I retry all process since run npm create hono@latest again, and still getting the error, I don't know if this happens because I choose the option to don't send metrics to cloudflare, is it forced required?
