Web Workers and synchronous calls

[bergwerf]

I noticed that this library uses WebAssembly, and that the initialization is async. However, subsequent calls to the library are sync (e.g. they do not have to be awaited). I imagined that all work would be done in a Web Worker running the compiled WASM, but then all calls should have been async. How does this work exactly?

For my application I am interested in using the CoordGen 2D layout algorithm. It might be valuable if this computation happens async, such that it doesn't block the UI thread when it isn't instant.

@bergwerf I suggest you take a look at https://github.com/rdkit/rdkit-structure-renderer, which is also available as npm package. It indeed does rendering using Web Workers to avoid blocking the UI thread. You may configure the number of Web Workers you wish to start. Have a look at the example index.html page and at the api_examples for inspiration.
