# node-pkginfo
|
||||
|
||||
An easy way to expose properties on a module from a package.json
|
||||
|
||||
## Installation
|
||||
|
||||
### Installing npm (node package manager)
|
||||
```
|
||||
curl http://npmjs.org/install.sh | sh
|
||||
```
|
||||
|
||||
### Installing pkginfo
|
||||
```
|
||||
[sudo] 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 <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:
|
||||
|
||||
``` js
|
||||
var pkginfo = require('pkginfo')(module, 'version', 'author');
|
||||
|
||||
console.dir(module.exports);
|
||||
```
|
||||
|
||||
```
|
||||
{ version: '0.1.0',
|
||||
author: 'Charlie Robbins <charlie.robbins@gmail.com>' }
|
||||
```
|
||||
|
||||
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.
|
||||
|
||||
```
|
||||
vows test/*-test.js --spec
|
||||
```
