NODE, also known as Node.js, is a JavaScript platform specifically for the development of applications that are likely to scale rapidly.

BEGINNER

⇒ Code Examples

→ You must be bilingual (Fr/En). Code examples are in English.

→ Let's start with very simple codes. The more you progress, page after page, the more sophisticated the scripts will be. However, you must go over 30 to 40 pages per level, before moving on to the next step...

→ In order to evaluate your codes, click on the icon on the left at the bottom of the page (gears), then choose a compiler from the list that will be open in another tab. Finally, test your work.

NOW REPRODUCE AND IMMERSE YOURSELF!

C 0001 - Hello World !
Reproduce this code (do not copy and paste!).

console.log("Hello world!");
C 0002 - Creation of a .js file
Reproduce this code (do not copy and paste!).

var http = require('http');

http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/html'});
  res.end('Hello World!');
}).listen(8080);
C 0003 - MySQL DB connection
Reproduce this code (do not copy and paste!).

var mysql = require('mysql');

var con = mysql.createConnection({
  host: "localhost",
  user: "yourusername",
  password: "yourpassword",
  database: "yourdb"
});

con.connect(function(err) {
  if (err) throw err;
  var sql = "SELECT users.name AS user, products.name AS favorite FROM users JOIN products ON users.favorite_product = products.id";
  con.query(sql, function (err, result) {
    if (err) throw err;
    console.log(result);
  });
});

CHOISISSEZ VOTRE COMPILATEUR

Reproduce this code, choosing one of the compilers below (don't copy and paste! It would be too easy). They all have the same function, just choose one according to your preferences.

When copying your code, replace the existing (default) code already in the compiler with your own.

Warning! For some of these compilers, you must choose the programming language yourself from the menu that is then offered. Of course, don't forget to click on RUN!
