commander-extra

A wrapper around commander.js

This wrapper allows you to use commander with an organized folder structure and some helpers.

Installation

$ [sudo] npm i commander-extra --save

Usage

Create a file that will be the entry point of your command:

var path = require('path');
var commander = require('commander-extra');
var pkg = require(path.join(__dirname, 'package.json'));

var program = commander({
    name: 'my-tool',
    version: pkg.version,
    commandsDir: path.join(__dirname, 'commands'),
    beforeHelp: function() {
        // This will be called before displaying help so you can add anything
    },
    // If this is true then a config file will be created in ~/.my-tool/config
    hasConfig: true
});

Then, to create your first command, create a folder commands and add a javascript file:

module.exports = function makeEvent(program) {
    'use strict';

    program
        .command('hello <mandatory> [optional]')
        .description('Command description')
        .action(function(mandatory, optional, command) {
            program.log.i('Normal output');
            program.log.e('Error');
            program.log.w('Warning');

            // This is only shown if the option -h or --help is used
            program.log.d('Debug info');

            // These need the hasConfig option to be true
            program.config.get('some.config');
            program.config.set('some.config', 'Some value');
            program.config.has('some.config');
        });
};

You can then test your command by doing:

$ node my-tool.js hello john smith
