Generate TypeScript Definition Files

[paf31]

To expose a PureScript library to TypeScript, we can generate .d.ts files from an externs file.

Would be nice to have, but not essential for a first release. Also, I'm not sure what to do with things like

foo :: forall r. { a :: A | r } -> { b :: B | r }

Closing this as wontfix. The type system really won't help with things like rows.

In case anyone is interested in this topic: I've written a tool to do this. See https://github.com/minoki/purescript-tsd-gen

I think @justinwoo has also worked on some stuff around this!

My thing is just a PureScript library in the end though https://github.com/justinwoo/purescript-ohyes

If PureScript compiled to TypeScript and could read TypeScript definitions, it would take over the front-end world.

That'd be nice, but TS can't (directly) express a lot of PS types and vice versa. Plus there's effects to consider.

I think tools that assist with some cases is the best we'll get really.

I think this would be really nice. It would make it much nicer to make libraries with purescript and make them usable with the typescript/javascript world. But also in integrating purescript components into existing TypeScript codebases.
