billypon/browserify-global

example

main.js:

console.log(__dirname);
console.log(__filename);

now you can bundle like this:

var browserify = require('browserify');
var b = browserify('main.js', {
	plugin: ['browserify-global']
});
b.bundle().pipe(process.stdout);

or like this:

browserify -p browserify-global main.js
