# Readme
This repository guides you to implement a server using Node.js. A first instance is created to understand how to set a server, then the server code is used to read the contents and printed out. Finally, a new server instance is prepared to prepare an `index.html` page and change dynamically its contents and LED status by reading the status option selected by the user.

## Static server
A static server is developed on static-server.js file:

```node
const express = require("express");
const app = express();
const http = require("http");
const server = http.createServer(app);

app.get('/', (req, res)=>{
        res.send('<h1> Hello World</h1>');
});

server.listen(4040, ()=>{
        console.log('listen on http://beaglebone-black.local:4040');
});
``` 

## Server information on a html file

```node
const express = require("express");
const app = express();
const http = require("http");
const server = http.createServer(app);

app.get('/', (req, res)=>{
        res.sendFile(__dirname + '/index-static.html');
        //res.send('<h1> Hello World</h1>');
});

server.listen(4040, ()=>{
        console.log('listen on http://beaglebone-black.local:4040');
});
```
the contents of the .html file is a common file.
