Is is possible to run multiple files concurrently using the

hi all, i'm just trying to make a simple form but for some reason it keeps submitting the form as if there's no

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)...

Hi, how would I go about reading a single line from
Deno.stdin synchronously?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?

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....
Closing a websocket server in a unit test
Hello, I'm an author of rpc lib and I'm currently writing unit tests for it. I am facing a problem of closing a server. How should I do it without

How to cancel or abort .pipeTo()?
I prefer not asking, but after I found (what I consider) an MDN easter egg, I realized this is probably not something I'm going to solve without help from runtime-implementers. https://user-images.githubusercontent.com/17692058/200146738-da3e8747-6c7f-4ec7-adb8-fbb8c8947d33.png
The example is straightforward, call
stream1.pipeTo(stream2) then, with full access to both stream1 and stream2 try to shutdown/cancel/close/abort/sabotage/nuke stream1, stream2 or even just the pipe itself (copy-paste example below). The big issue is that, because of the pipeTo the deno process never ends. I've tried absolutely everything I can think of, including inheriting from WritableStream, prototype pollution hacks, accessing probably-shouldnt-be-accessed-directly-symbol keys, etc and I've not got a hint of success
