We've been really enjoying using TypeScript for a while now and love the safety that the strong typing provides. However, getting data into the bounds of the type system, from say a call to a back-end service, can lead to run-time errors. One library that helps solve this problem is io-ts. It bridges the gap between compile-time type-checking and run-time consumption of external data by providing encode and decode functions. It can also be used as a custom type guard. According to our teams, it's an elegant solution to a rascal of a problem.
