Node.js debugging with VS Code

Debugging with VS Code

The free Visual Studio Code editor has built-in Node.js debugging facilities as well as debugger extensions for all popular platforms.

These are not used or required here because the debugger running in your container permits remote access. However, they offer some interesting development options.
