pkginfo

node-pkginfo

An easy way to expose properties on a module from a package.json

Installing pkginfo

  npm install pkginfo

Motivation

How often when writing node.js modules have you written the following line(s) of code?

Hard code your version string into your code

  exports.version = '0.1.0';

Programmatically expose the version from the package.json

  exports.version = require('/path/to/package.json').version;

In other words, how often have you wanted to expose basic information from your package.json onto your module programmatically? WELL NOW YOU CAN!

Usage

Using pkginfo is idiot-proof, just require and invoke it.

  var pkginfo = require('pkginfo')(module);
 
  console.dir(module.exports);

By invoking the pkginfo module all of the properties in your package.json file will be automatically exposed on the callee module (i.e. the parent module of pkginfo).

Here's a sample of the output:

  { name: 'simple-app',
    description: 'A test fixture for pkginfo',
    version: '0.1.0',
    author: 'Charlie Robbins <charlie.robbins@gmail.com>',
    keywords: [ 'test', 'fixture' ],
    main: './index.js',
    scripts: { test: 'vows test/*-test.js --spec' },
    engines: { node: '>= 0.4.0' } }

Expose specific properties

If you don't want to expose all properties on from your package.json on your module then simple pass those properties to the pkginfo function:

  var pkginfo = require('pkginfo')(module, 'version', 'author');
 
  console.dir(module.exports);

  { version: '0.1.0',
    author: 'Charlie Robbins <charlie.robbins@gmail.com>' }
