Nodejs + commander argument handling takes too much efforts

[harshadyeola]

When we pass args to command we need to apply checks manually on

• number of arguments
• argument type like number or string like

# Here we are checking no. of args should not be zero
# but we need to check max no. of args also
if (!pkgs.length) {
  console.error('packages required');
  process.exit(1);
}

Did you search for libraries?

There must be other libs to take care of that.
