Expose a method to show the help string whenever I want to, like it being the default command of my program.

Program would be something like:

program
  .version(package.version)
  .action(() => program.showHelp())
  .command('real command')
  .action((args, options, logger) => /* do stuff */);
program.parse(process.argv);

// ./myprog
/* ... prints help ... */

Elasticsearch can't index keys or values that are larger than 32kb, so we should add an option to our logger to truncate fields that are larger than this.
