Dev server continues to run after aborting `npm run dev` (Ctrl+C)

Description

I had to restart the dev server after pulling in a package. In my terminal, where npm run dev command was being executed, I pressed Ctrl+C to abort it. Then I ran npm run dev again and it failed with some reference to localhost:8080, and from what I understood, the port was already occupied. Indeed, when I went to localhost:8080 the app was still running even though npm run dev was terminated and the terminal was closed.

Steps

1. npm run dev
2. Ctrl+C
3. npm run dev

Results

• Expected: it should restart the dev server
• Actual: it fails with an error; the server isn’t halted and continues to run on localhost:8000

Brute-force fix

Kill the process manually. In WIndows, you can kill Node.js: Server-side JavaScript from Task Manager.

i had the same issue on windows solved it using the commands below remember these commands will only work in cmd not in gitbash this command will give you the process id of the process running on that specific port

$ netstat -ano | find ":3000 "

this command will tell you which program is using this port

$ tasklist /fi “pid eq {process-id}”

and this will kill that process

$ taskkill /pid {process-id} /f

Doesn’t seem to be directly related to this template. Plus we will be switching to webpack-dev-server in the coming days (#975), so this would have to be re-evaluated after that.
