Some time ago I released voft (Various Objects For TypeScript), a tiny utility library that brings some of the ergonomics of the Java VAVR functional library to TypeScript/JavaScript.
Why?
I missed VAVR's Try monad when writing Node back‑ends and React front‑ends: it lets you chain calls without drowning in try/catch blocks.
I wanted an async‑aware variant (AsyncTry) for promise chains.
Existing FP libs (fp‑ts, purify, etc.) cover similar ground but felt heavier for small projects, and I also wanted to challenge myself.
What's inside?
- Try – wrap any sync code, then .map, .flatMap, .recover…
- AsyncTry – same, but for Promise‑based flows; awaitable and chainable.
- Optional – lightweight Maybe.
- Either<L, R> – success/failure container with ergonomic helpers.
Early days – the API is still settling and there are probably bugs. I'd love feedback, issues and PRs!
Thanks for reading!
