Convert commands to observables

commander-rxjs provides a .observe() function to convert commands an RxJS observable.

Note: The .observe() can be used any place commander's .action(cb) function can be used.

import program from 'commander-rxjs';

program
  .command('order [item]')       // commander function
  .option('--two-day-shipping')  // commander function
  .observe()                     // convert to observable stream
  .do(command => {               // RxJS function
    console.log(command.args);     // --> { item: "JavaScript Stickers" }
    console.log(command.options);  // --> { twoDayShipping: true }
  })
  .subscribe();                  // RxJS function

// INPUT: amazon-cli order "JavaScript Stickers" --two-day-shipping
program
  .parse(process.argv)
