Any way to wait for server closed?

[howesteve]

Hello, this is more of a doubt.

So when I call this:

// ...
app.listen(3000))

.. a promise is returned, and even if I wait for it:

await app.listen(3000))

the next line is executed immediately.

My question is, how can I wait until the server is stopped to finish closing other resources?

try {
  //...
  await app.listen(3000))
  // ==> should be waiting here somehow until server stops listening; e.g.
  await app.closed() 
} finally (e) {
  // cleaning up resources
  databasePool.close()
  app.close()
}

Thanks

Hi @howesteve
Thank you for asking these questions, but it's not bug.

• There no app.closed() method
• app.listen() async/promise works properly, tested
• app.close() method code is here

Thanks. I never thought this is a bug. However, after listen() the execution should pause until the server exits, is that right?
But it's continuing right away. Let's see an example:

const app = require("nanoexpress")();
(async () => {
  await app.listen(3000);
  console.log(`I shouldn't print yet`); // it prints "I shouldn't print yet" immediately
})();

I was expecting the execution flow to pause at app.listen().

It waits until server starts. That at core level
