Electron Build Status

A simple command-line interface framework for node.js.

Features

  • reimagined process.argv parsing utility
  • framework for single or multiple command programs
  • automatic --help command generation with multiple theming options
  • built in cli coloring
  • chainable api

Quick Start Guide

This "Quick Start Guide" and the full API reference can be found on electron's documentation website.

Installation

The electron package is available through npm. It is recommended that you add it to your project's package.json.

npm install electron

Parsing Arguments

The argument parsing utility can be used independently of the program framework. Just pass the process.argv from any node modules and your ready to go.

The following command execution...

$ node cli.js build --minify --out saved.min.js

Could be captured as so...

var argv = require('electron').argv();

// objects
argv.commands;               // [ 'build' ]
argv.modes;                  // [ 'minify' ]
argv.params;                 // { out: 'saved.min.js' }

// helpers
argv.command('build');       // true
argv.mode('m', 'minify');    // true
argv.param('o', 'out');      // 'saved.min.js'

Recommend reading the "Argument Parsing Utility" section of the documentation to learn about the methodologies and specifics of each of the helpers.

Your First Program

To construct your first program, simply execute the electron export with a parameter of the namespace you wish to use for your program. Then proceed to define your settings and commands.

var myApp = require('../lib/myapp')
  , program = require('electron')('myapp');

/**
 * Define your program settings
 */

program
  .name('My Cool App')
  .desc('http://docs.mycoolapp.com')
  .version(myApp.version);

/**
 * Define your first command
 */

program
  .command('build')
  .desc('start a build task')
  .option('-m, --minify', 'flag to set enable minification')
  .option('-o, --out [file.js]', 'name of output file')
  .action(function (argv) {
    var minify = argv.mode('m', 'minify')
      , savefile = argv.param('o', 'out')
      , cwd = argv.cwd;

   program.colorize();
   console.log('Welcome to myApp'.gray + myApp.version);
   console.log('It works if it ends with '.gray + 'myApp ' + 'ok'.green);
   // etc...
  });

/**
 * Parse argv and execute respective command
 */

program.parse();

Your -h, --help and -v, --version will be generated for you automatically.

Recommend reading the "Program Framework" and "Constructing Commands" sections of the documentation to learn about all of the available chainable commands and theming options available to construct your programs.

Tests

Tests are writting in Mocha using the Chai should BDD assertion library. To make sure you have that installed, clone this repo, install dependacies using npm install.

$ npm test
