`multipart` file upload streams

I'm trying to handle multipart forms and I am new to Deno and noticed that the MultipartReader mentioned in a few blog posts seems to be gone in newer versions of the standard library. Does that also mean that there is no way anymore to control memory usage with something like a maxMemory property? Because as far as I understand you are supposed to just use request.formData() which provides no way of handling this.

deno_runtime inspector service not starting...

Hi! I'm embedding deno_runtime, and I can't get the inspector working. I set BootstrapOptions.inspect to true, and WorkerOptions maybe_inspector_server and should_break_on_first_statement. The server is set to listen on 127.0.0.1:9229. server in inspector_server.rs is called, and prints

Debugger listening on ws://127.0.0.1:9229/ws/5b5725e4-ac19-4f4d-ba1b-f6d44ce9430f
Visit chrome://inspect to connect to the debugger.
Deno is waiting for debugger to connect.

Deno Deploy and Digital Ocean PostgreSQL DB...how on earth?

https://github.com/denoland/deno/issues/10312 So since the issue above seems to take quite some time to fix because it apparently involves several upstream software, is there anyway to fix the "other side"? What specifically is so special about (for example) Digital Ocean's ca certificates that they are completely unusable with Deno/Deno Deploy/rustls/webpki (whatever the latter two are). I assume this isn't the case with every other certificate issuer or service or host (sorry I don't understand a lot about this, it's all a bit complex). I assume people are successfully connecting to their databases on other services through Deno. What I mean, is there any point in asking Digital Ocean support if they can workaround this on their side? Are they even able to do that? Is there anything I can do locally? Does anybody know of an alternative route/service that works?...

VScode Deno Extensions produces constant errors

I am currently using Deno with Opine in order to rewrite an API from JS to TS. While Opine only is used in one file, I chose Deno for the TS support and this I must have it enabled on all files in order to run(AFAIK). My issue comes with Deno constantly producing errors like the one pictured that I cannot find answers on how to solve. This pop up every few seconds making it extremely distracting, and as Errors their is no way to silence them even in VScode. I understand this means that deno features are not working and even after reinstalls they stop working after a little bit. Meaning I also loose functionality like hover and such ...

deno.lock multiple entry point best practices

Hi, I just upgraded to 1.28.0 and realized that lock files are here by default for deno.json config projects. I figure that means its time I adopted lock files. So I wanted to open a forum about best practices. I have read this doc https://deno.land/manual@v1.28.0/basics/modules/integrity_checking, which is a good start. I know at least that a lock file should be checked into git (which is less confusing than w/ node, where lock files change per OS and their advice on version control is pretty fuzzy. Here is my remaining question though, what happens when I have multiple entrypoints? Specifically, I am looking at this repo I own https://github.com/andykais/sqlite-native. I have three main module entrypoints: 1. src/mod.ts (this is what lib users will use) 2. test/*.ts (this is for running tests)...
