Is there a good dataframe library for deno?

I use the nodejs bindings for pola.rs for now but I'd like to move from nodejs to deno. This is my last blocker. Pola.rs is written in Rust. Would I have to wait for the wasm version of it?...

[resolved] CI failure TS2684

Hey, I'm currently working on a pull request for the Astro project. Unfortunately the CI doesn't like my code despite the latest Deno version (1.26.1). Does anyone know what the reason is and can possibly give me a solution? GitHub Actions run: https://github.com/withastro/astro/actions/runs/3200178618/jobs/5226807106....

How to import the Image class to Deno Fresh?

I'm trying to access an image's naturalHeight and naturalWidth. But when I construct the object new Image() I get a Reference Error that it is not defined. I figured I could import it from a preact module or something similar to (import {Image} from 'preact/image), but I simply couldn't find out from which module to import it.

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....
