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.

ADTs in Typescript
When working in a TS codebase I'll lean on this variant library, which works pretty well as far as simple sum types go (v3 is great but not stable yet).

disc-union - (yet another) library for working with discriminated union types
About half-way through writing this library I discovered that Variant existed... and does a great job at doing the exact same things (and more). I might not have started if I knew about that, but I'm glad I did because it has been a great learning experience!

ts-pattern: pattern matching library for TypeScript, with smart type inference
Oddly enough, this feature alone has been a a big draw to Rust, Haskell and functional programming in general for me... so it's nice that there's libs filling the gap for TypeScript. Here's another one I haven't gotten around to trying yet either.

Tool to normalize types (specifically intersections)?
I had to solve this for a project of mine.

disc-union - (yet another) library for working with discriminated union types
Lately I've been working with discriminated unions more and more, and I found myself writing a lot of the same boilerplate code over and over again, so I wrote disc-union to help with creating and managing discriminated union types. It allows you to easily define your types by simply writing constructor functions for them, and Typescript's type inference does the rest. It also provides functions for exhaustive type-safe matching and other common tasks.
What are some alternatives?
When comparing variant and disc-union you can also consider the following projects:
type-fest - A collection of essential TypeScript types
boxed - Essential building-blocks for functional & safe TypeScript code
TypeScript - TypeScript is a superset of JavaScript that compiles to clean JavaScript output.
ts-pattern - 🎨 The exhaustive Pattern Matching library for TypeScript, with smart type inference.
