cli-pipe

Accept piped data as an argument to your CLI app

This module allows you to accept piped data in your application along with directly provided arguments. It returns a simple array of all the arguments and flags, with any piped data pushed onto the end of the array.

Usage

First, install with npm:

$ npm install cli-pipe

Then include and call:

// File: test.js
var get_args = require('cli-pipe');

get_args(function (args) {
  console.log(args);
});

Run it like so:

$ node test.js first second    # Arguments provided directly
[ 'node', '/path/to/dir/test.js', 'first', 'second' ]

$ cat somefile.txt | node test.js first   # Piped data and direct args
[ 'node', '/path/to/dir/test.js', 'first', 'content of somefile.txt' ]

This module does not alter process.argv, so it is compatible with most or all other CLI helper modules (e.g. commander, meow).
