.NET Core can certainly run in well under 100MB, handle requests under 50ms and get running quickly under load. You also have async/await and type safety, scales horizontally. It's not JS/TS, so the skills are different and that's not idea but if you're in TS and squint, you're looking at C#.
Also far from perfect but I do think it's now a viable option as a replacement for node.
