How I unit tested types
Nice. Have you checked out tsd? Would you consider your library to be a viable alternative to tsd?

How to test TypeScript type definitions with Jest
The library we're going to use to execute these static type tests is one that I made called jest-tsd. It's a wrapper around tsd to make it really easy to use with Jest.

Typing is good but testing is better!?
But even with a very strict TS/ESLint configuration, you can't avoid a typing error. I looked for libraries to test types and I was very surprised to see that it is not a very common practice and there is not much choice. The most popular one seems to be tsd, unfortunately like all the other libs I found, it does not integrate with existing tools.

Testing TS Type Inference
How is this different than tsd ? https://github.com/SamVerschueren/tsd

How to generate declaration for only public members of a package?
Yep. Similarly I'm surprised there's no built in way to test typescript definitions, so I end up using tsd.

Is there any known way to measure coverage of... types?

⚛️ Explaining React's Types
Prior to React 18, it used to include an implicit children prop, making it suitable for components expected to have children. For a long time, though, the implicit children prop type has been removed according to React 18's type changes.

Introduction to TypeScript — What is TypeScript?
Additionally, because TypeScript has a well established and widely used install-base, there are already many different definition files in the wild for supporting non-TypeScript supporting projects. One of the more extensive collections of these typings lives at the DefinitelyTyped repository, which publishes the package's community typings under the package names @types/your-package-name (where your-package-name is the name of the project you're looking for typings of) that you can look for on your package manager.

Declaring JSX types in TypeScript 5.1
The TypeScript pull request was merged, so Sebastian (who helps maintain the React type definitions) exercised new powers in this pull request to the DefinitelyTyped repository for the React type definitions. At the time of writing, this pull request is still open, but once merged and shipped the React community we will feel its benefits.
