Question

I am a newbie in Node.js (and Express) and I am trying to make sense of this. Say I have a website with 3 pages (can be GET or POST): /, /page1, /page2. What should I do so that every page is handled by a separate JS file?

app.all('/', function(request, response)
{
    // Get home.js to handle this request and response
});
app.all('/page1', function(request, response)
{
    // Get page1.js to handle this request and response
});
app.all('/page2', function(request, response)
{
    // Get page2.js to handle this request and response
});

Better yet, is there a way to define a wildcard so there is not so much repetition? Something like this:

app.all('*', function(request, response)
{
    // Get *.js to handle this request and response. * is whatever the URI string is
});

Continuing my discussion with @Alex. Here’s how I did it. Any gotcha?

// app.js
var EXPRESS = require('express');
var URL = require('url');
var PATH = require('path');

var app = EXPRESS.createServer();

app.all(/^\/([a-zA-Z0-9-]+)$/, function(request, response, next)
{
    var page = request.params[0];
    if (PATH.existsSync(__dirname + '/' + page + '.js'))
    {
        require('./' + page).handleRequest(request, response, next);
    }
    else
    {
        next();
    }
});

app.all('*', function(request, response)
{
    response.send('Catch all');
});

// --- truncated for brievity


// page1.js
exports.handleRequest = function(request, response, next)
{
    response.send('Howdy!');
};
