Check out https://github.com/woutervh-/TypeScript-is. It works as a compile-time transformer which emits the type guard code for a given type and narrows down the type for you. You just call `is<T>` (returns a bool and narrows if true) or `assertType<T>` (narrows or throws an error). We've used it in production with great success. |
