Render the HTML page and inject the json_code to be used in a script tag:

JS:

router.get('/user', function(req, res, next) {
    var json_code = { 'hello': 'world' };
    res.render('user', { title: 'Express', data: JSON.stringify(json_code) }); 
});

HTML/JADE:

script
    var json_code = JSON.parse(#{data})
