Calling already defined routes in other routes in Express NodeJS

Question

I am writing a web app in node.js using Express. I have defined a route as follows:

app.get(\"/firstService/:query\", function(req,res){
    //trivial exampl

Similar to what Gates said, but I would keep the function(req, res){} in your routes file. So I would do something like this instead:

routes.js

var myModule = require('myModule');

app.get("/firstService/:query", function(req,res){
    var html = myModule.firstService(req.params.query);
    res.end(html)
});

app.get("/secondService/:query", function(req,res){
    var data = myModule.secondService(req.params.query);
    res.end(data);
});

And then in your module have your logic split up like so:

myModule.js

var MyModule = function() {
    var firstService= function(queryParam) {
        var html = ""; 
        return html;
    }

    var secondService= function(queryParam) {
        var data = firstService(queryParam);
        // do something with the data
        return data;
    }

    return {
        firstService: firstService
       ,secondService: secondService
    }
}();

module.exports = MyModule;
