html node.js form input

Question

I am following this previously asked question but am receiving this error:

usera@usera-VirtualBox:~/Desktop/test/sample$ nodejs smallNode.js /home/usera/Desktop/test/sample/smallNode.js:3 var app = express(); ^ TypeError: object is not a function at Object.<anonymous> (/home/usera/Desktop/test/sample/smallNode.js:3:11) at Module._compile (module.js:456:26) at Object.Module._extensions..js (module.js:474:10) at Module.load (module.js:356:32) at Function.Module._load (module.js:312:12) at Function.Module.runMain (module.js:497:10) at startup (node.js:119:16) at node.js:902:3

What am I missing?

Server side code:

var express = require('express');
var bodyParser = require('body-parser');
var app     = express();

//Note that in version 4 of express, express.bodyParser() was
//deprecated in favor of a separate 'body-parser' module.
app.use(bodyParser.urlencoded({ extended: true })); 

//app.use(express.bodyParser());

app.post('/myaction', function(req, res) {
  res.send('You sent the name "' + req.body.name + '".');
});

app.listen(8080, function() {
  console.log('Server running at http://127.0.0.1:8080/');
});

Here are the results from running npm install. It looks like there is a warning during the install process so maybe that's the issue...

Yes, edited original post to include results from `npm install express` — JRR, Feb 07 '16 at 14:55
Thats an old version of express... you should at least use v3, or better v4 to have it export a function. — crackmigg, Feb 07 '16 at 14:58
So should I be trying to figure out 3.x.x/4.x.x version information for the `package.json` file or is there some other approach so I don't have to figure out what the latest greatest version is? Where can I find version information? — JRR, Feb 07 '16 at 15:07
Got it, updated the `package.json` file to something like this: `"express": "~4.0.0"` — JRR, Feb 07 '16 at 15:47
