Debugging Aleph apps in VSCode

How are you debugging Aleph apps inside Visual Studio code?

NOTE: I'm referring to debugging my application that's running inside the Aleph framework, not actually debugging Aleph itself.

Similary (but not the same of course) as Nextjs:

Start the server:

$ aleph dev -reload

INFO Server ready on http://localhost:8084/

Then try to attach to the process in the launch.json:

  "configurations": [
    {
      "type": "pwa-node",
      "name": "Aleph: Run",
      "request": "attach",
      "port": 8084
    },

But no chance. Has anyone out there got this configuration working in Aleph yet?

Throws after I add your launch.json @Dizzy

With JS debugger (nightly) enabled:

This is not fully working because breakpoints are not being hit. But you can put debugger in your code and it will stop there.

.vscode/launch.json

      "runtimeExecutable": "deno",
      "runtimeArgs": [
        "run",
        "--inspect",

    }
  ]
}
