Haxe can be a powerful tool for developing JavaScript applications. Let's look at our first sample. This is a very basic example showing the toolchain.
Create a new folder and save this class as Main.hx.
import js.Browser; class Main { static function main() { var button = Browser.document.createButtonElement(); button.textContent = "Click me!"; button.onclick = (event) -> Browser.alert("Haxe is great"); Browser.document.body.appendChild(button); } }
To compile, either run the following from the command line:
haxe --js js/app.js --main Main
Another possibility is to create and run (double-click) a file called compile.hxml. In this example the hxml file should be in the same directory as the example class.
--js js/app.js --main Main
The output will be js/app.js, which creates and adds a clickable button to the document body.
To display the output in a browser, create an HTML-document called index.html and open it.
<!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <title>Haxe Application</title> </head> <body> <script src="js/app.js"></script> </body> </html>
