Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

TypeScript is terrible for library developers
I'm very curious, which "Redux code" are you referring to here?
I don't think the `redux` core lib ever shipped any Flow types itself. Looking at the FlowTyped repo, I see community typedefs at https://github.com/flow-typed/flow-typed/tree/master/definit... , and the Git history suggests those were indeed written by community members.
(of course on the flip side, _I_ didn't even start learning TS myself until 2019, and goodness knows _that_ has been a lot of trial and error over time :) )

Is Flow moving away from (or toward) broader community relevance?
As for configurability of whether casts should error, in my experience with flow it's paradoxically riskier to rely on a type nag when refactoring an unknown "offending" type casts. I've ran into cases where upgrading flow raised a cast issue, it got "fixed" it in a way that made the type system happy, but inadvertently broke tests because falsy values are tricky like that. Here's an example where a type nag showed up for someone refactoring, they did what they thought was reasonable to silence it, and proceeded to accidentally break the entire tool (slipping through tests and code review, to boot). This happened in the flow-typed tool of all places.

Creating a modern JS library: TypeScript and Flow
The process of supporting Flow users is extremely similar to that of TypeScript. Instead of adding the definition file to "types" in package.json, make a .js.flow file alongside every .js file that is being exported (for example, if you export lib/index.js, make sure to create lib/index.js.flow with the definitions). See the docs on how to create such a definition. If you want to support Flow yourself, don't publish to flow-typed; it's mainly meant for community members to create their own types for third-party packages and publish them there.

⚛️ 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.

Announcing TypeScript 5.1
Relatively infrequently. Normally, if an npm package is popular and doesn’t have its own types, there will be a community provided types declaration file available from https://github.com/DefinitelyTyped/DefinitelyTyped
