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.

volder is a powerful JavaScript schema builder for value parsing and validation. Define a schema and validate values, volder schema are extremely simple to use, it has custom error messages, custom types, nested schemas.
What does this library provide that is not provided by Yup, Zod, Superstruct (a personal favorite), Joi, Nope, computed-types, typanion, and all the other validation libraries?

Since the last time I shared it the API got significantly improved; rather than using decorators we now use member properties, making the syntax work the same whether you use TypeScript or plain JavaScript. All option types are 100% inferred, and validated/coerced thanks to a companion library called Typanion.

Type-Safe Printf() in TypeScript
There is an implementation of SQL that operates on a table shaped type, entirely at type level. For your amusement: https://github.com/codemix/ts-sql
There are a bunch of more practical takes that codegen types from your database and generate types for your queries, eg: https://github.com/adelsz/pgtyped
To me the second approach seems much more pragmatic because you don’t need to run a SQL parser in a fairly potato interpreter on every build
- Functions and algorithms implemented purely with TypeScript's type system
- Que opinan de esta forma de actualizar estados complejos en React, creen que es buena practica o tienen una mejor forma?

How to Sell Elixir Again (2023)
> If I would level criticisms at dialyzer it would be its sometimes difficult to read warnings, it’s speed (despite being multithreaded) and the race conditions in the VS Code plugin (which is looking for extra maintainers – if I had time I would help).
One of the advantages of TypeScript is that VSCode is written in TypeScript, and both VSCode and TypeScript are developed by the same company, so there's a really nice synergy there. I imagine Kotlin users feel the same way using Jetbrains products, and Swift users feel the same way about XCode.
Dialyzer looks interesting, but I can't imagine giving up on the expressiveness of TypeScript. Some of the things you can do with generics, mapped types, intersection types, template literal types, conditional types, and utility types are almost mind boggling. It's difficult to reap all of the benefits of static analysis without some of these advanced type operators. The type manipulation section of the TS manual is really underrated.
Someone for example wrote an SQL parser in TypeScript that requires no runtime code [1]. It can infer the types of an SQL query's result based on an SQL string without any runtime code execution. There was a similar project where someone built a JSON parser entirely using the type system [2]. There's also an ongoing discussion on Github about the the fact that TypeScript's type system appears to be a Turing-complete language with some other cool examples [3]. My point is that the type system is incredibly expressive. You rarely run into an idiom that can't be typed effectively.

Pls can we go back to traditional languages?
If anyone saw this meme and thought, "damn parsing a type from a SQL query, that looks useful" (as I did), the source appears to be from here.

Which allows for things like this type that implements a simplified SQL query parser checked against a provided 'database' object:

This project was my go-to "nifty but pointless" example for TS string literal types before this article :)
