From my experience (used Typescript for a few projects for frontend and tried Flow but ran into bugs/missing things) both TS and Flow type system are easy to fool and in the end you are still writing javascript. I've never heard of Elm or PureScript being used for backends, users would prefer Haskell I presume. With elm it would require using ports for almost everything, I haven't used PureScript so I can't comment on that. And as far as ecosystems go, I would prefer using the Python one rather than the Node one.

There are some PureScript projects that I know of running on Node, although it is admittedly less common. I'm currently working on a framework to build REST services in PureScript, so hopefully the situation will improve shortly.

I just decided to use TypeScript for a new REST API I'm writing. I'd have liked to use Rust instead, but I felt it was still too early (and can't afford the productivity hits of using a new-ish ecosystem). So far, TypeScript's type system isn't perfect, but it is strict enough to help me catch errors before runtime. Also, there's the (huge) added benefit of making code more readable and self-documenting. I think I've only had one instance where I violated a type at runtime, but keeping the type system in mind as you're writing your code, you know exactly where those things can or can't happen. I am really enjoying using Visual Studio's excellent IntelliSense and debugging features, which are on-par with any other web language I've used. Generally speaking, the typing makes hints and autocompletion far better. Overall, I'd give the whole experience a 7 out of 10. I don't really know of a more productive way to write asynchronous code at the moment.

I'd be curious to know how Flow is easy to fool (other than uninitialised class members).
