Just a quick tip for anyone looking to share data between multiple elements in a mobile plugin.

With web elements this was never much of a problem, because you can use the global `window` object as a bridge between elements. Mobile elements are a different story, there’s no `window` (or DOM) in the React Native runtime. The good news is there’s an equivalent: the `globalThis` object, which is available in both environments and works the same way as a shared space.

Here’s a quick example of each:

**Web element**

```auto
window.sharedVar = "example shared text";
window.sharedFunc = function () { /* ... */ };

```

**Mobile element**

```auto
globalThis.sharedVar = "example shared text";
globalThis.sharedFunc = function () { /* ... */ };

```

One element writes a value (or a function) onto `globalThis`, and another element can read it. A handy pattern is to have one element register a function on `globalThis` that a second element can call, for example to notify it that some shared data has changed.

Hope it’s useful!

Awesome tip. I’ve been looking at dabbling in some mobile plugins soon and use the window a lot in web plugins.
