Is it possible to expose some renderer method to work in a web worker and then apply it to the Handsontable configuration that is in the main thread?
(Angular)Render styles in web worker service
We don’t have any official examples of web worker for Angular, but this topic was also raised by other users here: https://github.com/handsontable/handsontable/issues/5816#issuecomment-564097741
There you can find an example in React, but it shows that it should be possible to do, and I believe that main rules are similar.
