Railway Oriented TypeScript

on YouTube ↗33m

" summary

Claim: apply railway-oriented programming to TypeScript by turning ordinary functions into a two-track Result (success/failure), writing a chain combinator and using a fpts library to compose validators, DB updates and logging. Live-coded examples return typed Result objects, the type system enforces exhaustive handling and catches miscompositions, and the talk contrasts this with Promises which cannot distinguish domain errors from panics.
