You can do that with nodejs too, e.g. edit package.json and main.js in vscode, hit hotkey to npm install hit hotkey to run node ./main.js. This is what I'm doing at the day job.

What I'm trying to do there is to have a client and server in the same ./src, hot-reloaded module-wise on "save" only when a relevant part changes, and vscode to typecheck both at the same time. The language similarity is also a goal. It's a little more than just a traditional lazy-compile-restart cycle.

Non-monorepo non-ts-only guys do not experience my issues, because they only have one environment per project (or per src-<target>), and don't try to make their build configs incompatible with other parts of a build system. I tried to push it as far as it could go to evaluate the state of things for writing non-standard slightly different web apps. To make a ts-react app, they just use CRA, for a backend they just use node main.js.

But anyway this shows how interdependent this ecosystem is, instead of being full of orthogonal possibilities.
