Hello world

Developing JavaScript code is easy with Haxe. Let's see our first HelloWorld example :

class Test {
    static function main() {
        trace("Hello World !");

Put this class into a file named Test.hx and create the file compile.hxml in the same directory with the following content:

-js test.js
-main Test

To compile open you terminal and type:


And drag the folder where you saved the files, into the terminal. It will look something like this:

cd /path/to/folder/

Press enter and type:

haxe compile.hxml

If an error occurs, the terminal will display that. If everything went smoothly like it should, this will produce a test.js file that can be embedded into an HTML page such as this one :

<head><title>Haxe JS</title></head>

<script type="text/javascript" src="test.js"></script>

  1. Put this code into a test.html file.
  2. Open it with your browser (like Google Chrome)
  3. It will display Hello World in your Console.
  4. (Google Chrome > Hamburger menu > More Tools > Developers tools)


If you want to experiment with this code, you can do that without installing Haxe.

Below you can see and try the same example code at try.haxe.org without installing Haxe.
