Nodejs/Expressjs app structure

Question

Say i have this code to separate routes in expressjs:

module.exports = function(express,app,client) {

    app.get(\'/\', function(req,res,next) {
               


        

Answer 1

How about express-train ? i have been using it lately, and it plays well with complex app structures.

Answer 2

In the expressjs download package, there is a folder called "mvc". The author provides a good example for a tiny&efficient mvc structure. Going through the code, you will get much inspiration.

Answer 3

There is a similar question here which you should read: How to structure a express.js application?

1) All your query logic should be put in models (modules that reside in /models for example)

2) Separate all your routes (controllers) into modules (and put them in /routes for ex) By routes I mean for example: - all the logic for "Users" routes go into /routes/users.js

Try to keep you app as MVC-ish as possible.

Small example for your app above:

app.js

// configuration for express etc
require('./routes/index')(app)

routes/index.js

var model = require("../models/users.js");

module.exports = function (app) {

  app.get('/', function (req, res, next) {
    model.get_recent(function (err, results) {
      // do stuff with your results
      res.render('index');
    });
  });

}

models/users.js

module.exports = {
  get_recent: function(callback) {
    var query = "SELECT * FROM users LIMIT 10";
    database.query(query, callback);
  }
}
