Mean-stack handling 500 (Internal Server Error)
<p>Currently this is what I have as my nodejs/expressjs serverside code:</p>

<pre><code>// Init Express Web Framework
var express = require('express');
var app = express();
var path = require('path');


// Set view engine to EJS &amp; set views directory
app.engine('html', require('ejs').renderFile);
app.set('view engine', 'html');
app.set('views', path.resolve(__dirname, 'client', 'views'));

app.use(express.static(path.resolve(__dirname, 'client')));

//app.use(function(req, res, next) {
//    res.header('Access-Control-Allow-Origin', '*');
//    res.header('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Accept, Authorization');
//    res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE');
//    if (req.method === 'OPTIONS') {
//        res.send(200);
//    }
//    else {
//        next();
//    }
//});


// Database Connection
var mongoose = require('mongoose');
var configDB = require('./server/config/database.js');
require('./server/routes/capture');
require('./server/routes/comment');
require('./server/routes/vote');
require('./server/routes/follow');
mongoose.connect(configDB.url);

var bodyParser = require('body-parser');
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: true}));               
app.use(bodyParser.text());                                    
app.use(bodyParser.json({ type: 'application/json'}));

// Main route
app.get('/', function(req, res){
    res.render('index.html');
});

// API 
var api = express.Router();
require('./server/routes/capture')(api);
require('./server/routes/comment')(api);
require('./server/routes/vote')(api);
require('./server/routes/follow')(api);
app.use('/api', api);

app.use(function(err, req, res, next) {
    res.status(err.status || 50, function(res) {
        res.render('error.html');
    });
});

// Port Settings
app.listen(process.env.PORT || 3000, process.env.IP);
console.log('Listening on port ' + process.env.PORT);
</code></pre>

<p>In my client I have 2 views: my <code>index.html</code> where all my content renders, and I have a <code>error.html</code> where I want to redirect people to if they get a 500 error.
Currently if people go to a link that does not exist, they get redirected to the main page.</p>

<p>But when I use an url that exists but with a parameter that doesnt, I get the 500 (Internal server error).</p>

<p>Using the code on the bottom of my serverside, I would think that these errors get redirected to the error.html page, but for some reason it doesn't.</p>

<p>On my server log it gives no errors, seeing it should be redirecting, but on my client side, I simply load the page with the wrong parameter (and ofcourse no content, except for the empty elements, seeing nothing is found).</p>

<p>How do I solve this?</p>

<p>Thanks</p>
