npm/node works fine in Windows (and I'm pretty sure it's the same with composer), so why do you want to use it in WSL?
Edit: this is a genuine question of an engineer, who uses Git/npm/node for fullstack development on Windows 10 every day. What kind of setup do you have and what UX do you expect, that requires running the tools in WSL?
