Modifying HTML Website from Node.js Server to Display File Data

Not sure what the output needs to be following your example, but I would surly start by using express.js in your project. This will simplify greatly your RESTfull api.

Depending on how noob, you are to node, I will try to guide you thru the simplest way I can! ;)

You first need to install Express in your node project.

From the command shell you type npm install express --save to install the node_module. The --save adds the dependency to your package.json. (Depending on your user's role, you might have to use the sudo command (sudo npm install express --save)

Using the following link Express "Hello World" example you will find the simplest example on how to use Express.

So if we use your example your setting might look like this.

var express = require('express')
var app = express()

app.get('/', function(req, res){
    res.sendFile(__dirname + '/clientMonitor.html');
});

app.get('/client-data', function(req, res){

    /* Depending on what you use on your client side, 
      you may get data here than send a response in json or flat data.*/

    res.json(aJsonObject); // For json response {"Context-Type": "application/json"}

    // OR

    res.send('AnyValue'); // Will send 200, {"Context-Type": "text/html"}

    // OR

    res.sendFile(__dirname + '/someFile.html');

});

app.listen(8080, function () {
  console.log('Example app listening on port 8080!')
})

For your client side, you may use any plugin such as DataTables.net or custom-made function that updates your data in your table using Ajax calls to refresh the information.

Hope this will help solve your issue!

If you decide to use POST instead of get, you will do something like :

app.post('/client-data', function(req, res){    
   var data = req.body.data;
}

Or if you wish to use queryStrings in the Get url parameters, you will do soemthing like :

app.get('/client-data/:id', function(req, res){
   var data = req.params.id;
}
