Accessing writeOut from actions

[hypeJunction]

I am working on a web app that doesn't have access to stdout and I was able to replace the output of the program with .configureOutput(), but I am not really sure how I would access the API from inside the actions. All examples use console, and I don't see any public API to write/print with Command. For now, I am using a proxy on top of window.console to be able to print from the actions, but perhaps there is a more elegant way, or something that I am missing.

There isn't a custom API for using writeOut and writeErr directly. The main use of writeOut is displaying the help, and there are .help() and .outputHelp() routines to trigger that directly. For errors, there is the .error() method to display and handle a custom error the same way Commander does.

However, you can retrieve the configured output and use it yourself:

program
  .action((options, command) => {
    const output = command.configureOutput();
    output.writeOut('Hello, world!\n');
  });

An answer was provided, and no further activity in a month. Closing this as resolved.

Feel free to open a new issue if it comes up again, with new information and renewed interest.

All good, thanks a lot. Our work is on pause for now, but we will pick it up later. I will let you know how it goes.
