# 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

``` js
exports.version = '0.1.0';
```

* Programmatically expose the version from the package.json

``` js
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.

``` js
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 ',
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:

``` js
var pkginfo = require('pkginfo')(module, 'version', 'author');

console.dir(module.exports);
```

```
{ version: '0.1.0',
author: 'Charlie Robbins ' }
```

If you're looking for further usage see the [examples][0] included in this repository.

## Run Tests
Tests are written in [vows][1] and give complete coverage of all APIs.

```
npm install
npm test
```
