AbortSignals not working in Deno

Hi there, I'm trying to create a Hono server with a disconnect handler. When I cancel the request from my client, the abort signal from the raw Request object never changes to true. This code works on both Hono and Bun, so I think this is an issue with Deno's fetch API. See example below (requires Hono)

import { Hono } from 'hono'

const app = new Hono()

async function stall(stallTime = 3000) {
  await new Promise(resolve => setTimeout(resolve, stallTime));
}

app.get('/hello', async (c) => {

  // Should show up when hitting Cancel in Postman
  c.req.raw.signal.addEventListener("abort", () => {
    console.log("Aborted");
  })

  // Simulate a long-running task
  await stall(10000);
  return c.text("Hello from Hono!");
})

Deno.serve(app.fetch)

import { Hono } from 'hono'

const app = new Hono()

async function stall(stallTime = 3000) {
  await new Promise(resolve => setTimeout(resolve, stallTime));
}

app.get('/hello', async (c) => {

  // Should show up when hitting Cancel in Postman
  c.req.raw.signal.addEventListener("abort", () => {
    console.log("Aborted");
  })

  // Simulate a long-running task
  await stall(10000);
  return c.text("Hello from Hono!");
})

Deno.serve(app.fetch)

Cannot use import maps

Hi there, I'm trying to make a project root alias @ so I don't have to suffer through relative path import hell (../../../../file.ts) However, when I specify "@/": "./" in the imports section of deno.json, I get an error from VSCode stating this:

The import specifier can be remapped to "@/absolutePath/file.ts" which will resolve it via the active import map.

The import specifier can be remapped to "@/absolutePath/file.ts" which will resolve it via the active import map.

Therefore, I either have to use absolute imports for every file or use only relative imports. I want to be able to use both. Is converting the project root to @/ not possible without some sort of src directory? Thanks in advance.

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 Can this be replicated in Deno?
