Import local typescript file so both Deno (LSP) and TS work?

Seems like Deno wants the import to end with .ts while TS wants no file extension. Is there any way to change either of them to accept the other?...

how to cli run node modules without --compat

So deno run --compat has now been removed in favor of npm: specifiers https://deno.com/blog/v1.26#--compat-mode-removed. I am sure this consolidates a lot of code, but I am unsure how I can gain back certain functionality. For instance, I could run a solidjs template out of the box from deno with compat like so: deno run --compat --unstable --allow-env --allow-read --allow-run --allow-net node_modules/.bin/vite dev Using npm specifiers, I dont seem to have the same capabilities. deno run --compat --unstable --allow-env --allow-read --allow-run npm:vite...

Intellisense on an import not working, works for friend

I cannot for the life of me get import * as bsdeno from "https://raw.githubusercontent.com/KivalEvan/BeatSaber-Deno/main/types/beatmap/v3/mod.ts" to have intellisense. I try typing const b: bsdeno. and nothing shows up. I tried restarting TS and deno language servers, tried restarting VSC, tried updating deno, and restarting my computer. No dice.. my friend is using the exact same import and intellisense is working fine....

Command doesn't work in deno task but works outside of deno task

The command in question:

(find . -name '*.js'; find . -name '*.as') | grep -v bundle | xargs wc -l | sort

(find . -name '*.js'; find . -name '*.as') | grep -v bundle | xargs wc -l | sort

Run it in Terminal.app, it works. Run it in Deno, it freezes! This changes when I remove the () to join two commands together....
