How to detect happy-dom environment?

[diegohaz]

Hi! I'm currently using the following code to detect JSDOM environment:

const isJSDOM =
  typeof navigator !== "undefined" && navigator.userAgent.includes("jsdom");

How do I do this for Happy DOM? Is there a recommended way to reliably detect both JSDOM and Happy DOM (and maybe other alternatives)?

Hi @diegohaz! 🙂

It is possible to detect that it is an Happy DOM environment by checking if window.happyDOM is defined.

Example

if(window.happyDOM) {
    // Do something
}

I have added the issue #482 for adding it to navigation.userAgent as well.
