Profiling WebGL memory usage

What is the appropriate API to monitor the size of the heap in a WebGL build?

I'm trying the API detailed in this article from 2016 but I don't know if it still applies to WebAssembly builds.

Thanks!

 

Following up, I used the plugin code from the above article in my game, left it running overnight and the heap usage returned by the API had increased so I think this API still works now, with WebAssembly builds.
