Please note: This is an answer to your main question regarding Jade rendering. What you do with socket.io is up to you, but of course, you should consider sending only small packets of data back to the browser and do the rendering by client side templates instead.

However, yes, you can manually render with Jade in Node.js without the need of the Express framework. Please see Jade API documentation for all the methods and options you can use.

Try this in your app.js:

var jade = require('jade');
var renderFunc = jade.compileFile('./views/layout.jade');
var html = renderFunc({ title: 'Express' });
console.log(html);
