Getting Deno and Nuxt to work well together

I've experimented with Nuxt 3 in the past and wanted to use it for a new project I'm working on, but at the same time, I wanted to try out using deno, and since Nuxt shows up on the list of supported frameworks, I decided to give it a try and use both of them together. The problem comes up when I try to add packages either from npm or jsr and nuxt never seems to find them. I tried creating a project with npm and moving the folder from the package into node_modules and it worked on the deno version, so I'm guessing it has something to do with how each one handles adding imports? I was trying it with @std/fmt Is there any way to fix it? Should I just use npm until nuxt adds better support for deno? Or is there any other framework similar to nuxt where I can use vue and where I can also use deno?...

How do I make Deno run code when it is closed out on Windows

According to the documentation there is Deno.addSignalListener but it only handles on Windows when you use CTRL+C or CTRL+BREAK, how do I make it handle all possible closes like Deno.exit or closing it from the task bar?

Global install with “Failed resolving binary export”

Trying to install a cli with deno but I’m running into two issues. The cli is “@cyclonedx/cdxgen”. 1. It fails to run the npm lifecycle scripts for SQLite no matter what I do (I tried setting “-A” to allow all permissions). 2. Ignoring number 1 it fails to run the cli because it “did not have a bin entry for ‘@cyclonedx/cdxgen’. Instead the “bin” is an object of key values, one of which being “cdxgen”. And Deno is aware of that as it lists them all as “possibilities”. However, I don’t know what to do with this information. Is there anyway I can tell deno to call the “cdxgen” binary, like npm would by default?...

Questions about files and what happens when other programs writes to them

I am a noob at programming. There is this video game I play named Team Fortress 2 and it has this option called condebug which makes it create a file with all of the contents of the in-game console, this file is updated in realtime. I'm going to use this in deno to detect in-game button presses and team-changes to control VLC Media Player. I want to make a script with Deno that reads this file out in realtime and decodes it to perform actions when it sees certain groups of text, I am wondering w...

Properly Integrating JSDoc and Type Definitions for Deno and JS

Hi everyone! I’m working on a JavaScript codebase designed for both Deno and browsers. We’re adding documentation and types to publish it on JSR, but I’ve hit some roadblocks. Issue 1: JSDoc Using JSDoc for @param and @returns doesn’t work with deno doc or JSR—they ignore the types, likely because they rely on .d.ts files for type information. This seems limiting for *.js files but might be a technical constraint....

How to reveal a long inferred type in order to publish to jsr

I've published a package to jsr (@schoolai/ts-prompt) and everything went well. Now, I'm improving the package and I have a function whose type is quite complex. Typescript is inferring its type correctly. However, when I go to publish to JSR, I get the "this function is missing an explicit return type" error/warning. Normally, I would just hover over the function in my editor (Zed, in this case) and it would oblige and show me the full inferred type--I'd then copy paste it into the code and call it a day. However, now that I have a very large/complex type, the editor elides some of the type information:...

Without using a framework, how do I compile natively supported TS in Deno into static JS?

If I am not mistaken, this used to be possible with the built in bundler which is now gone. How do we go from dev-time TS to prod-time JS without a framework or custom transpiler in the middle? Basically, help me get from deno init to deno "prod" - how to turn those main.ts files into runnable js?
