The most powerful and lightweight API that allows you to develop your original Haxball(www.haxball.com) host, client, and standalone applications both on node.js and browser environments and also includes every possible hack and functionality that you can imagine.
Node.js package is not updated yet, so its version is incompatible with the current documentation. I will probably update it next week. In the mean time, you can work inside the browser.
Running the node app throws the following error
Cannot read properties of undefined (reading 'create')
I'm surely missing something, but I'm not sure what exactly, considering how early I am on the development process
