Since the last time I shared it the API got significantly improved; rather than using decorators we now use member properties, making the syntax work the same whether you use TypeScript or plain JavaScript. All option types are 100% inferred, and validated/coerced thanks to a companion library called Typanion.

How to check that an 'unknown' object has a specific key and that the key is a specific type?
⭐ Recommended: Doing this manually is a ton of work, and if you're dealing with unknown objects often it would be better to lean onto a validation library to simplify it. My personal favorite is superstruct, although lots of people like joi or zod. They all do the same thing

How do you "stitch & glue" types for all your needs?
The class-validator / class-transform looks really nice for formatting/validation but there is also joi. suretype is attractive since theoretically typeconv could generate jsonSchema for json-schema-faker and Open API docs.

A few questions about type guards
Since Typescript is just a language and not a library of some sorts, it doesn't add runtime functionality. If this is what you're after, there's so many libraries that help converting unknown's into known types - joi, yup, superstruct (my choice), purify-ts Codec, io-ts
