I resonated with the post as I'm in a similar position but I'm really sad that typescript chose just to be a thin layer on top of javascript.

The sentiment mostly comes from having the JS ecosystem mostly being untyped and having to interact with it.

That being said I tried io-ts but found it undocumented, missing examples and hard to write. For future libraries/projects I'm looking to try again ReasonML, tried in the past but had to write too many bindings.

Author here. I used io-ts when the documentation is still on its root README.md. Apparently it has been moved to https://github.com/gcanti/io-ts/blob/master/index.md

I've been rolling io-ts into an app I inherited and have been porting to TypeScript. If you know a little Haskell/Scala type FP, the docs are plenty. I think the lib could definitely have a shallower learning curve for folks coming from Go though (what my back end devs write mostly).
