I want to take analytics on continuous data and do live visual analysis on it. I simulate playing a batch of games that have a chance component from emitting a Cmd Msg for a random value. After computing the analysis of the batch, I use that analysis to simulate more games, yielding another random …

That is unavoidable. If you do expensive computation on the main thread you will block it. Seems like using a web worker would be a great fit for your use case, given you don’t want to split or slow down.

Good suggestion-how would I approach implementing that? Do you have resources or tools you recommend?

https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Using_web_workers https://package.elm-lang.org/packages/elm/core/latest/Platform#worker And some time reading and experimenting is all you need. There are other resources if you google but they are for older elm versions, and use JS…

Thank you for the resources, they are valuable and saved me a good deal of time exploring! I may also look for an open source example, and post it here if I find one.

I started to implement the infrastructure stuff for webworker communication, the actual game never came to be but the plumbing is still there, if you want to have a look https://github.com/mfeineis/game01

Awesome, thanks for mentioning!

[image] anon5324703: so update emits a GameGenerated Msg which triggers update to emit a GameGenerated Msg which triggers update . . . ad infinitum. I’ve identified that this section is causing an update loop that crashes the browser, perhaps because it runs out of memory. How do I show the liv…

That is a good point, it would definitely make sense that it is slow because perhaps the view is rerendered to quickly, it is something I considered. But since the entire interface is SVG, I’m not sure how to optimize that. So it seems that indeed a web worker is the best route, feeding interspersed…

I am working on library that would enable you to make large computation without blocking “main thread”. Idea is that you define a step function and then offload computation in batches so that there are no dropped frames (or at least minimum dropped frames). I am currently stranded on finishing som…

Take a look at elm-queue. It is a simple pool queue I wrote. I wrote about it in this other post with an example also: Many messages causes slow rendering
