    I'll throw https://github.com/woutervh-/typescript-is in the mix as well.

    I'm a fan of typescript-is. Provides both compile time and run time validations

    For what it's worth, thanks to TypeScript transformers (a feature baked into the compiler), one can create a transformer library that verifies an object is valid for any TypeScript type and conveys that information to the typechecker. And indeed, it's already been made. It allows to parse unknown into a given T. This is nice, because one can generate a JSON schema out of a TS type, for other languages/codebases to integrate safely.

    Then there's also typescript-is, which is pretty neat because it converts actual compile-time type definitions to runtime type checks, so it doesn't require changing the type definitions.
  • JSON Schema === Runtime Type System for TypeScript

    typescript-is. This uses a compile-time transformer to generate code for type-checking. You'll need to use ttypescript instead of typescript to compile your code (I recommend setting this up with ts-patch). It won't work if your build pipeline is actually using something like esbuild or Babel to transpile TS->JS.

    If you're not using a bunch of generics, check out typescript-is [1]. It takes little work to get it setup, but it generates run time type checks for you. I understand why typescript decided to not add this functionality to the core of the language, but it's starting to feel like the largest missing piece of typescript is a built-in way to generate run-time type-checks for user-defined types from just the type definition.

    The happy medium we've found with that module is using the runtime type-check on anything "unsafe" to bless the result using typescript-is's equals functionality, but still allowing programmers to use casting with a comment justifying its necessity. For us our list of unsafe is results pulled from the db, anything parsed from JSON, and incoming request bodies (which can be a special case of parsing from JSON, but not always).
