father

A package parser that can resolve self and dependencies, supporting spm / component.

---

Install

$ npm install father -g

Usage

// using SpmPackage
var Package = require('father').SpmPackage;
var pkg = new Package('path/to/package')
console.log(pkg.name);
console.log(pkg.version);
console.log(pkg.main);
console.log(pkg.dependencies); // return a object contains dependencies
console.log(pkg.get('each')); // return a package named each

// using ComponentPackage
var Package = require('father').ComponentPackage;

Properties

The properties of Package instance

pkg.id

Unique id for each package

= {pkg.name}@{pkg.version}

pkg.name require

Package's name

pkg.version require

Package's version

pkg.main

Entry point of the package, default is index.js

pkg.dependencies

Package's dependencies, each one will return a Package instance

pkg.files

All used files will exist in pkg.files, it will be parsed from pkg.main. Each file contains dependent files (no deep dependencies).

Example below

{
  files: {
    'index.js': {
      dependencies: ['each', './feature']
    }
  }
}

pkg.dest

The base directory of the package

pkg.origin

The origin package info

pkg.output

Export files when build

Method

pkg.get(pkg.id)

Get a package of id

pkg.set(pkg)

Set a package

pkg.getPackages()

Get all dependent packages

Options

The options when instantiation

new Package('path/to/package', options);

extraDeps

Config an extension as key, when that extension is found, value will be added to deps

new Package('path/to/package', {
  extraDeps: {
    'handlebars': 'handlebars'
  }
});

If one file require('./xx.handlebars'), handlebars will be added to the dependencies ['./xx.handlebars', 'handlebars']

entry

Generally, files will be parsed from pkg.main, no dependent file will not be included. entry will be another entry point.

Files

// a.js <- pkg.main
console.log('no require');

// b.js
require('./c');

// c.js
console.log('no require');

Code

new Package('path/to/package', {
  entry: ['b.js']
});

Return

// without entry
{
  ...
  files: {
    'a.js': []
  }
}

// with entry
{
  ...
  files: {
    'a.js': [],
    'b.js': ['./c'],
    'c.js': []
  }
}

ignore

// a.js
require('b')

If you don't want to parse package b, you can specify ignore. And it won't parse the dependencies of b.

new Package('path/to/package', {
  ignore: ['b']
});

Custom

If you want to use it for your package, you can extend Package and override readPackage.

var Package = require('father').Package;
var Custom = Package.extend({
  readPackage: function() {
    // 1. read config file, E.g. component.json
    // 2. return a package contains id, name, version, dependencies, main, dest, files, origin
    // 3. dependencies should contain id, name, version, dest
  };
})

Example for returned object by readPackage

{
  id: 'a',
  name: 'a'  
  version: '1.0.0',
  main: 'index.js',
  dest: '/home/user/a',
  dependencies: {
    b: {
      id: 'b@1.1.0',
      name: 'b',
      version: '1.1.0',
      dest: '/home/user/a/components/b'
    }
  }
}
