Unable to create Vue app using the Documentation on Deno

I was trying to check if Deno is a good environment for developing Vuejs applications. I am following this guide - https://docs.deno.com/examples/vue_tutorial/ It fails at the point where it shows how to implement api for listing dinosaurs, and updates vite.config.js with @deno/vite-plugin ...

`deno bundle` and React Router

Is bundle intended to fully cover projects would normally require third party build tools? Asking primarily because I ran into a snag trying to migrate a React project off of Vite -- that snag appearsto involve React Router -- which, itself, uses Vite as a dev dependency. (Tangentially, if I keep using Vite, its syntax parsing throws errors on attempting to use text imports)...

I noticed that upon updating to Deno 2.4.2 the hono RPC types stopped working. I noticed that there were some tsconfig default changes in the update, do I need to manually fix one of them?

deno deployed app not reporting to hosted collector

Hello team and community! My Deno Deploy app isn't sending any OpenTelemetry data to a hosted collector. It works great locally with my LGTM (Docker setup) – I get all the traces and logs there, so I know my code and OTel config are good....

`@jsxRuntime` pragma

The TSConfig reference claims that adding a /* @jsxRuntime automatic */ comment to a file has the same effect as setting compilerOptions.jsx to "react-jsx" for that file, but this doesn't seem to be the case. I have a main.tsx file with the following content. ```ts /* @jsxRuntime automatic / / @jsxImportSource npm:hastscript@9.0.1 */ console.log(<></>);...

Issue with Oak, Superdeno / Superagent after going from Deno 2.3 to 2.4

Hi, I've been using Oak + Superdeno (Superagent) with relatively ok DX so far. Recently after upgrading from Deno 2.3 to 2.4, all my tests failed because of this: ``` error: Error: Request has been terminated Possible causes: the network is offline, Origin is not allowed by Access-Control-Allow-Origin, the page is being unloaded, etc. at Test.Request.crossDomainError (https://jspm.dev/npm:superagent@6.1.0!cjs:674:13)...

Is there a way to view active resources keeping the Deno event loop open?

I'm trying to debug a Deno process mysteriously staying alive when it should close. Is there an equivalent of the getActiveResourcesInfo API from node? When I try to do import { getActiveResourcesInfo } from 'node:process'; in Deno I get the error Uncaught SyntaxError: The requested module 'node:process' does not provide an export named 'getActiveResourcesInfo' so it looks like this particular API is unimplemented in Deno. I've also tried looking around in the inspector using `deno run --ins...

React Library Best Practises

Hi, I'm trying to migrate our app-sdk and app-sdk-react from Node to Deno. The app-sdk went fine without issues and is able to be imported and uesd across Deno and Node/npm worlds without issue. But I'm having issues with React. I don't have react in my dependancies as I use Denos built in support. My compiler options are; ``` "compilerOptions": {...

multiple connections to local kv with sqlite from different thread

If I have multiple workers on different thread, occasionally accessing the same kv with sqlite backup, will that cause any problem other than occasionally db being locked (which I can just try again) I'm building a compiled local app so shared kv instance on Deno Deploy is not an option....

Does `deno bundle` have a TypeScript API?

I'm excited to use the new Deno bundler. In my past experience with esbuild, I've almost always needed more config than a shell one-liner and frequently plugins. Is there a TypeScript API exposed? I tried inspecting the Deno global, looking at the docs, and searching for a package on denoland but didn't see anything.

Deno + Tauri, deploy and make app usable on my device forever

Is it possible for me to make my tauri app available on my phone (iOS) all the time. Basically, I want to download the app I made onto my phone, and make it available even if I didn't run deno task tauri ios dev on my laptop and didn't have to keep my phone connected to the internet to use it. Not sure if I should be asking here or in the tauri server (I am asking in both), but just curious if it was possible. Currently I can test it both on simulators and my device, but I want to keep it on m...
