javascript - How to configure dynamic routes with express.js

Question

I have a route.js which looks like this:

module.exports = function(app) {

  app.get('/tip', function(req, res) {
    res.render("tip");
  });

  app.get('/article', function(req, res) {
   res.render("article");
  });

  app.get('/article1', function(req, res) {
   res.render("article1");
  });

  app.get('/article2', function(req, res) {
   res.render("article2");
  });

  app.get('/article3', function(req, res) {
   res.render("article3");
  });

  app.get('/modules/:name', function(req, res) {
    var name = req.params.name;
    res.render('modules/' + name);
  });

  app.get('/modules/esaver/:name', function(req, res) {
    var name = req.params.name;
    res.render('modules/esaver/' + name);
  });

};

Considering i have over 200 different routes to create, i would end up with stuff like 'article1', 'article2' etc

and my app.js is like:

var express = require('express')
  ,http = require('http')
  ,fs = require('fs')
  ,path = require('path');

var app = express();

html_templates = __dirname + '/html_templates';

app.set('views', html_templates + '/views');
app.set('view engine', 'jade');

app.use('/Core', express.static(__dirname + '/Core'));


app.listen(3000, function () {
 console.log("express has started on port 3000");
});

require('./html_templates/controller/routes.js')(app);

Is there any dynamic way to create this?

I would do the same thing you did for /modules/:name

app.get('/article/:id', function(req , res){
  res.render('article' + req.params.id);
});

It would be more meaningful from a rest point of view.

If you cannot do it for any particular reason you might want to do something like:

var articlesEndpoints = ['/article2', '/article3'];
articlesEndpoints.forEach(function(name) {
  app.get(name, function(req, res) {
    res.render(name);
  });
});

Is this what you meant?
