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)...

How can I enable type checks while running fresh

I want to relay on the code being type checked and yelling at me when I made a mistake, but deno task start in a fresh project doesn't seem to care by default. Is there some config I can change or at least some other script I can run in parallel to check the types? (I also observed that VSCode plugin seems to indicate more type related errors than my Jetbrains IDE, does somebody know why?)...

securing access for deno deploy?

We are creating a page using fresh, that is only for internal usage inside our company. We would of course love to use deno deploy for it, but is there a good way to limit the access to both the rendered frontend and the API, maybe even with something similar to cloudflare access? We are currently looking into a way to add a custom middleware, butaybe there are simpler solutions, or even alternative ways of hosting the page (without going through tons of infrastructure setup)?...

Learning how this works under the hood

Recommended resources to learn how this stuff works that can be understood by a dummy without a background in computer science? For a guy like me, becoming proficient at coding amounted to more or less like learning what goes with what and remembering how to get things to happen. I'm very limited by my lack of understanding how any of this (runtimes, bundlers, compilers, etc etc) works under the hood. I want to level up....
