Auto-attach debugger to node child processes

[szszoke]

There is a feature of VS Code called JavaScript Debug Terminal. It looks like a regular terminal but (almost) any running node process will start debugger session in VS Code.

You can read more here: https://code.visualstudio.com/docs/nodejs/nodejs-debugging#_javascript-debug-terminal

This is implemented via a bootloader script: https://github.com/microsoft/vscode-js-debug/blob/main/src/targets/node/bootloader.ts

The terminal uses the NODE_OPTIONS environment cariable to pass a --require argument for the bootloader script, which then talks to VS Code via a pipe to open a debugging session.

This effectively creates a debugging session for any node process in the terminal, so to avoid noise, the bootloader tries to ignore some instances bases on command like arguments (like npm install).

This feature would be useful to for scenarios where a node process is often restarted during development, lile restarting a server if the files change.

It is also just more convenient to start a process and get a debugger session immediately without having to configure anything.

It seems that it's also a must have to make the debugger compatible with SST
