NPM Types issue?

Hey, does anyone have any idea why the p5js package doesn't work in vscode? I can run the code and it seems to be alright, but I can't get any npm package to give me auto-completion?

Is there a performance boost on the pro plan of deno deploy?

I'm trying to figure out if my app will run with more resources or respond quicker using a pro plan vs the free plan. I did notice that I would benefit from multiple deno kv read regions on the pro plan.

express types

I was creating a server using express and even after type annotating the request and response correctly, I get this error. One of the most weird behavior is, when I did setup the project initially, everything was working fine. The type annotation, the auto-suggestion, everything. When I closed the file and opened it again, the type annotation is there, but there's no auto-suggestion, and i get this weird error....

(Not FFI related) "Unable to load deno" dyld issue MacOS

On an old version of MacOS deno 1.41 works, but all versions past 1.41 (including 2.x) result in a "unable to load" dyld issue. Was there some core change to deno around the 1.42 update?...

Using Deno 2 for simple HMR/static site dev server with Vite

We have a dead simple frontend which is 100% clientside. Just a folder of html files with some .ts imports. We are trying to unify tooling around Deno 2, but haven't been able to get this working to develop our frontend. Are there docs (specifically for Deno 2.x) for Vite setup? I'm trying really hard to keep a simple Deno setup without re-introducing node/npm stuff (just a simple deno.json config) but can't seem to get Vite working. With npm it was sufficient to just have a vite [folder of html files] dev script but no luck with Deno, can't escape unresolved dependency errors from Vite. I'd love a simple solution, it would be a shame to introduce a bunch more config for such a simple use case....

Learning Process for Web Development?

Hey guys, coming from a backend background, I've mainly been coding in Python/Java. Saw a video on YT about Deno 2 and was thinking about learning web dev for fun. Can someone more experienced outline what steps I should take to start learning? The only exposure I have really is using REST APIs to get json data. Also some basic understanding of how HTML works on a webpage, but otherwise I'm totally lost! So far I've installed deno, installed the VSCode deno plugin, created a test project and executed main.ts to see the simple add example. Should my next step be doing some typescript tutorials? What about after I've learned typescript? How do I go about creating my first website? I don't have any plans to get a job in this area, so preferably I'd like to do everything the Deno 2 way right off the bat....

how to get single result from Subprocess

Hey, I am new to deno and I am learning how to communicate between parent and subprocess. In this doc: https://docs.deno.com/examples/subprocesses-output/ it shows it needs to use console.log() through std.out in subprocess. If there are multiple console.logs in subprocess, then all of them will be captured by parent. Is there a way for subprocess to only return a single result back to parent process? Thanks in advance!...

Using TypeScript with .env file

I was wondering if anyone could point me in the direction of resources that would guide me through the process of creating type safe environmental variables for a Deno project. I am using the @std/dotenv library to read the vars but how to make them type safe. What would be considered best practice? Should I use Zod or can I extend an existing type/interface that exists? Your help is gratefully appreciated....

Using libraries from JSR in SvelteKit

Hi! I'm playing around with using SvelteKit with Deno 2, and tried to import a library from Deno's standard library to use that with SvelteKit. This, however, adds it into deno.json instead of package.json and I'm not able to import it in Svelte code. What would be needed to be able to import modules from JSR and make them work in SvelteKit?
