impulse-bin

node.js CLI module runner

• Adapters for commander.js and node-optimist
• Basic set of long-con console loggers for stdout/stderr/verbose with color

Purpose

• CLI scripts that are easier to test without running the executable.
• Reduce boilerplate.

Example

bin/myproj

Executables are reduced to thin loading calls.

var bin = require('impulse-bin').create();
bin.run(require('commander'), require('./lib/cli/myproj'));
 
// Or if your CLI module's run() function is a generator:
bin.runGenerator(require('commander'), require('./lib/cli/myproj'));

lib/cli/myproj.js

While the rest is separated into input parsing and input consumption.

• init() receives a CLI input provider like commander.js or node-optimist for you to configure.
• run() receives the parsed this.options and this.args from the provider.

exports.init = function(provider) {
  provider.option('-c, --config <dir>', 'Config file');
};
 
exports.run = function() {
  this.exitOnMissingOption(['config']);
 
  this.stdout('using config file: %s', this.clc.green(this.options.config));
 
  // ...
};

Pass arguments from bin/myproj to the lib/cli/myproj.js

// bin/myproj
bin.run(require('commander'), require('./lib/cli/myproj'), 1, 2, 3);
 
// lib/cli/myproj.js
exports.run = function() {
  console.log([].slice.call(arguments)); // [1, 2, 3]
};
