feat: stdio for cli apps

[jtmcdole]

Description

I wrote a server using package:shelf and had built a cli interface for managing the backend state. I ported over to dart_frog and have sense lost that cli, even in non-dev mode. Maybe I missed some documentation - but is it possible to get stdio in production mode?

Requirements

• stdio works in built mode.

Hi @jtmcdole 👋
Thanks for opening an issue!

Are you able to provide a link to a minimal reproduction sample that illustrates the issue you're facing? Thanks!

  try {
    stdin.lineMode = true;
  } catch (_) {}

  await for (var char in stdin) {
    var str = utf8.decode(char).trim();
    stdout.writeln("Hello $str");
  }

@jtmcdole Still don't think I have enough context 😅
Is this code in a route handler?

Is the CLI + shelf server you wrote publicly available? Just want to get a better understanding of the working setup you had.
