Download OpenFL

Haxelib (Option 1)

OpenFL is available to install from Haxelib. It supports HTML5, native desktop, native mobile, AIR and Flash development from a single toolset and the Haxe programming language.

To get started, install Haxe globally on your system.

With the latest versions of Haxe and Neko installed, open a command-prompt (Windows) or terminal (macOS/Linux) and run these commands:

haxelib install openfl
haxelib run openfl setup

In order to check if OpenFL has been installed properly, try running the openfl command:

openfl

Run a Sample

You can use the "openfl create" command for a list of available samples.

openfl create

For example, here is how to build and run the DisplayingABitmap sample on HTML5:

openfl create DisplayingABitmap
cd DisplayingABitmap
openfl test html5

Next Steps

Now that OpenFL is installed, you can choose a code editor or learn how to use OpenFL by creating your first project.

NPM (Option 2)

If you would like to use OpenFL for a web-only project, OpenFL is also available on npm.

Start by installing Node.js and npm globally.

Then, install Yeoman for generating a new OpenFL project:

npm install -g yo generator-openfl

This workflow supports TypeScript, Haxe, ES6 JavaScript or ES5 JavaScript-based development, but it is not designed to cross-compile to native desktop or mobile targets.

mkdir NewProject
cd NewProject
yo openfl

Run a Sample

There are many OpenFL samples you can try, depending on the code environment you wish to use:

• TypeScript
• Haxe
• ES6 JavaScript
• ES5 JavaScript
• ActionScript

Choose a sample, then npm install and npm start in the local directory to start a development server (with hot-reloading enabled):

git clone https://github.com/openfl/openfl-samples-ts
cd openfl-samples-ts/features/display/DisplayingABitmap
npm install
npm start

Next Steps

If you do not have a code editor already, Visual Studio Code is a good choice for that integrates well with OpenFL and NPM.
