An easy way to expose properties on a module from a package.json
curl http://npmjs.org/install.sh | sh
[sudo] npm install pkginfo
How often when writing node.js modules have you written the following line(s) of code?
exports.version = '0.1.0';
exports.version = JSON.parse(fs.readFileSync('/path/to/package.json', 'utf8')).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!
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' } }
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>' }
