var browser = run();
browser.pipe(process.stdout);
browser.write('console.log(document.location)');
browser.end();
$ browserify main.js | browser-run

var browserify = require('browserify');
var browser = require('browser-run');
 
browserify('main.js').bundle().pipe(browser()).pipe(process.stdout);
