// main.mjs
import inspector from "node:inspector";

console.log(`process.env.NODE_OPTIONS: ${process.env.NODE_OPTIONS}`);
console.log(`process.env.VSCODE_INSPECTOR_OPTIONS: ${process.env.VSCODE_INSPECTOR_OPTIONS}`);
console.log(`inspector.url(): ${inspector.url()}`);
console.log("pausing...");
debugger;
console.log("pause ended");

In the VSCode new terminal dropdown menu, open a 'JavaScript Debug Terminal'.

Node:

$ node main.mjs
Debugger attached.
process.env.NODE_OPTIONS:  --require /home/nayeem/.vscode-server/bin/c9d77990917f3102ada88be140d28b038d1dd7c7/extensions/ms-vscode.js-debug/src/bootloader.js  --inspect-publish-uid=http

<Press 'Continue' on the debugger toolbar>

When this works, you should get a similar result with Deno:

$ deno run -A main.mjs
Debugger listening on ws://127.0.0.1:53539/ws/6921f55a-769e-4a9c-9e32-3f9fc94cb447
Visit chrome://inspect to connect to the debugger.
Debugger session started.

<Press 'Continue' on the debugger toolbar>
pause ended
Program finished. Waiting for inspector to disconnect to exit the process...
Debugger session ended
