How to read Chunked request body?

Hello! Is it possible to read a chunked request body using for await? It seems to only read up to the point where the reader is empty and then stop. Since some chunks might only show up after some delay, I need it to read until 'zero-length chunk' is sent, meaning the chunked body is over.

Deno event loop and gui application

Hi, I am trying to write custom gtk library in deno using gtk-rs and deno_runtime. I already have initial rendering of components but i am having trouble understanding how to setup event loop for gui application. Currently i am using tokio's new_current_thread and block_on on deno's execute_main_module but this way setTimeouts don't seem to be executed which I suspect is because there is no event loop. execute_main_module seems to already call run_event_loop but should i just call it in loop or is there a proper way to do it using tokio? and how does event_loop_middleware fit into all this?
The other slightly related question is how do i schedule updates from the button clicks if the click listener closure is setup in the #[op(v8)]? thanks for your help...

How are deno processes/isolates managed in Deploy?

Hi, I'm writing a multiplayer game in Deno and currently all of the game state is kept in module-scoped objects, there's no database or any other form of persistence, yet. It all works as expected when I'm developing locally, but sometimes when testing in Deno Deploy, it's as if there's multiple instances of the game running and which one I'm connecting to is random (using the same URL.) Does Deploy create multiple simultaneous isolates for the same deployment? Is the only solution to implement...

Can I create a Fresh project inside another Deno project?

I would like to create a dashboard for my application (a minecraft bot), and I would like to use fresh to do so. I want everything to be contained inside the app's directory, so could I create a fresh project inside my current project? and then start the HTTP server programmatically? Or is there a better solution for something like this?...
