Answer 1

If I understand correctly, you could for example use hat. Especially the rack function.

Call rack() repeatedly to generate new IDs which are checked for collisions.

code

var hat = require('hat');
var rack = hat.rack(9, 10);

console.log(rack());
console.log(rack());

output

$ node test.js
109
461

The following will work. The routing is an example and for reference https://github.com/kof/node-jqtpl/

Node:

app.get('/randomtest', function(req, res){
    res.render('random.html', 
      {rnd: function(min, max) {
        return Math.random() * (max - min) + min;
      }
    });
});

Template:

${rnd(1,10)}

The min/max control what gets outputted.
