^ the voice coding (and eye tracking) system referenced by the author. I use it every day. It's actively developed, has some unique capabilities, and the community is great!
It'll be easier if you can still mostly use your hands since you can incrementally move over to voice coding/control, and the built-in functionality and community commands have truly progressed. There's also the eye tracking functionality if it's difficult for you to use a mouse/trackball etc.
There is a community-maintained Talon VSCode plugin, but no explicit TypeScript integration. That's a great idea, though! I think some folks use VSCode snippets to help their workflow. I personally want to get to the point where I can utter commands that can write the correct code in whatever language/context I happen to be in, and maybe something even higher level than that. The Talon author and community members are already thinking along those lines, as evidenced by upcoming APIs that make Talon easier to use and even more configurable/extensible than it already is.
