Default imports not working

I have an import like this:

import Stumper from "stumper";

import Stumper from "stumper";

I can't call any of the methods that exist on the default export. The Stumper object contains all of the exports from the entire library. I have the ability to use Stumper.default but I feel like that should not be necessary....

Error occurs when using React third-party component library

I want to use react-phone-number-input component in my project, but it gives error when I incorporate the component in my code. Picture 1 is the error it gives in browser and picture 2 is the error it gives in terminal. I wonder if anyone knows what's going on here or knows how to properly include third-party component library in the project? I created a small project to reproduce the error I got just for referrence: https://github.com/MingdaMa/fresh-react-third-party-library...

Is there a way to run a command from a package in a workspace?

Something like: deno task server:check which would run the task "check" in the "server" package in my workspace.

Will my server stop crashing with this error if I upgrade to a paid subscription? It's very frustrating for me and visitors to my website.

Include DLL files in deno compile

I'm currently building a CLI application with Deno that I want to compile into a standalone executable which uses FFI. I learned about deno compile, but I'm also stuck on how to include the DLLs that are used via FFI in my output binary. I don't want to include the DLLs separately after the binary is built, but I want to be able to ship a single binary. For example, nexe.js allows users to add static files under resources https://github.com/nexe/nexe?tab=readme-ov-file#resources...

Running Fresh app on Windows with pm2

I'm trying to run a fresh project in a production environment (windows server) but for some reason whenever I run deno via pm2 it panics with a "The handle is invalid (OS Error 6)" message when I try to run it. I was also able to reproduce this on a regular windows 11 install. Interestingly I'm unable to reproduce this on a mac device which I used to develop the website. Is there some sort of config setting I need to enable for pm2 other than specifying deno as the interpreter? I'm using deno 2.0.3...

Deno cron timeout

I've got an app running on Deno deploy with a cron that triggers each two days, i noticed that after 6 ~ 8 minutes the cron interrupts the task and marks it as successful even if it didn't finish, i'm looking around for info if the Deno cron functionality got some timeout config and trying to understand why it's happening, the cron should run for like ~20 minutes.

Vite plugin's global variables are `undefined` when using Deno

Anyone run across this before? Running Deno 2 and Vite 6beta. I built a third-party Vite plugin, and now I'm testing it in a "native" Deno project (deno.json, not package.json, etc). However, all of the packages and dependencies are from npm. My Vite plugin defines a global like so. ```js ......

`deno compile` executable not working with cross-platforms

I have a basic app (frontend using vite and backend using oak) which upon a button click displays a message from the backend. This app is working totally fine on my personal laptop having Ubuntu (24.04.1 LTS), after running deno compile -A --output linux_app main.js, and then running ./linux_app to see my app running on http://localhost:8000. I'm using the useState hook - import { useState } from "react";, hence node_modules 's existence being there in my project. The issue arises when I compile the app to a Windows executable by specifying --target x86_64-pc-windows-msvc. I get the following warning: Warning The node_modules directory may be incompatible with the target system. ...
