When using koa, it has no effect

[godkun]

After starting the Koa service, the browser accesses port 3000, and then checks the c8 report and finds that it has no effect

I had the same issue, however the issue is not coming from c8, it's from how Nodejs handle the flag NODE_V8_COVERAGE Here what i'm doing on my project (express):

function closeServer() {
  server.close(() => {
    process.exit(0);
  })
}

process.on('SIGINT', closeServer)
process.on('SIGQUIT', closeServer)
process.on('SIGTERM', closeServer)

Closing the server properly before exiting the process. ref: https://github.com/nodejs/node/issues/29896

@bcoe I believe we can close this 😁

@olivierodo an you confirm that this works with never releases of Node.js that contain the fix @olivierodo points to?
