Typing is good but testing is better!?
As a Vitest user I want to be able to test my types with it. So I wrote my own type assertion plugin for Vitest.

Enforcing Localization through Types
Typescript doesn’t natively provide an Opaque type that we can use to define a string that has already been localized. If the data looks like a string, Typescript will consider it a string. We can however use utility types that simulate opaque types, like the Opaque definition in type-fest:

Boost Your JavaScript with JSDoc Typing
With these powerful features, you can create dynamic and expressive types. One last thing I want to mention before moving on, is that you can install libraries with which you can add more types to your project like type-fest or utility-types. These libraries contain a lot of useful types that you can use in your project.

Essential Code Organization Principles
Also, it’s not as restrictive as mutability tools — if you know what you are doing and want to ignore this limitation for a particular case, you can apply the -readonly modifier or the Writeable type from type-fest or ts-essentials.

Best practice for typing server data for get vs post in client code
Remember you can derive one type from another type so you can make sure they don't diverge. SetOptional type util

All JavaScript and TypeScript features of the last 3 years explained
Some folks have built whole SQL databases and DSL compilers in the TS type system. These tend to be toy projects with disclaimers not to use them. But the type system being Turing complete[0] (for better or worse), pretty much whatever you can imagine. This project[1] is one I actually return to frequently for practical ideas.

Preventing more parameters being passed than needed by a type definition?
Try the Exact method provided by Type Fest, looks like it does what you're looking for
-
Creating a derived type of only required parameters from a base type?
This is a fairly common scenario and available via libraries like type-fest or implementable with a couple lines of code.
