Get stdin from runtime

I am currently running the following code inside of an

Effect.promise()

Effect.promise()

using Bun:

      process.stdout.write(promptMessage);

      const value = await (async function () {
        for await (const line of console) {
          if (line === undefined || line === "") {
            process.stdout.write("Please enter a valid response: ");
            continue;
          }
          return line;
        }
        return '';
      }());

      process.stdout.write(promptMessage);

      const value = await (async function () {
        for await (const line of console) {
          if (line === undefined || line === "") {
            process.stdout.write("Please enter a valid response: ");
            continue;
          }
          return line;
        }
        return '';
      }());

The console iterator and process.stdout.write are provided by Bun, or at least Bun's Node compatibility. I noticed that many examples provide a Platform requirement to effect depending on whether the runtime is Bun, Node, Deno, etc. Does this allow one to write code like this in a platform-agnostic manner?

If it does, I haven't yet been able to figure out what API to use -- it doesn't look like Effect's

Console

supports reading input, and I can't really tell if the platform packages provide anything of utility. It would be great to know what the best practice for this kind of thing would be. Thanks in advance for pointing me in the right direction!
