Hi! Instead of VSCode/Codium I would recommend Pulsar. See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1060778 (ITP: pulsar-edit -- A Community-led Hyper-Hackable Text Editor (formerly Atom)).
However, to get any Electron app in Debian somebody would need to package Electron first, see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=842420 (RFP: electron -- Build cross platform desktop apps with JavaScript, HTML, and CSS).
