Doesn't Check for Port Conflicts When Running Multiple Instances

[Muhammad-Sarfaraz]

What version of Hono are you using?

4.6.10

What runtime/platform is your app running on? (with version if possible)

Cloudflare

What steps can reproduce the bug?

Run two hono scripts,

npm run dev

What is the expected behavior?

When running npm run dev , Hono.js should check for conflicts to see if something is already running.

What do you see instead?

But it starts as usual.

Hi @Muhammad-Sarfaraz

This is not a Hono-side issue. It's not a bug.

Hi @yusukebe,
Thanks for the clarification! I understand this is not a Hono-side issue and isn’t a bug. However, it might be helpful to include a warning, as running both scripts on the same port can cause confusion.

Whether or not it displays warnings is also not a Hono-side issue; Hono does not know how the application is launched.

I think it is the responsibility of the runtime side to detect them.
Hono is just a framework, or a HTTP router like expressjs to be more precise, and detecting port conflicts would be adding code that is not its primary responsibility.

Got it, I will mention it in the Cloudflare Wrangler Repo.

Okay. Closing the issue.
