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 Runtime Validators and DX, a type-checking performance analysis of zod/superstruct/yup/typebox
What's prompted me to look at this is my tRPC+Zod editor experience at work has become unusable. 2-3 seconds to just get autocompletion options on a tRPC path, and then another 2-3 for the next path, repeat. When investigated using TypeScript's tracing tools the data entirely points back to my team's Zod DTOs. What I learned is that Zod's performance is okay at the start, but when you start using methods like .extend/.pick/.omit (and so on) the performance regresses in the order of a magnitude. Rather than making this into a "Zod considered bad" post, I wanted to investigate how the alternatives which can be integrated with tRPC fare, and see whether I can do better.

Ten Years of TypeScript
When you can write a busy beaver machine in the type system, LOC ceases to be a good indicator or how long something should take to typecheck, imo. If you're frustrated with your build, you should use the trace tools on the TS wiki[1] to track down what types are slow to check, so you can attribute the slowness to the appropriate library authors/yourself and decide for yourself if the speed/correctness tradeoff they've made is right for you.

How to upgrade TypeScript versions - what's your process regarding breaking changes?
So I want to update my (very large*) project from TypeScript 2.3.3 to the latest version, and I know that a breaking changes doc exists.

Tired of Typescript? Check out ReScript!
ReScript is a fully typed language with an easy to understand JS like syntax, blazing fast compiler, that compiles to JavaScript. You can easily drop it into an existing project, and there is even a way to generate TypeScript types if you want to add it to a TypeScript project!

Learning Elm by porting a medium-sized web front end from React (2019)
If you’re a front-end developer, you should checkout ReScript[1], supposedly a JS-oriented successor of ReasonML and developed by the ReasonML team.

ReScript: Rust like features for JavaScript
ReScript is "Fast, Simple, Fully Typed JavaScript from the Future". What that means is that ReScript has a lightning fast compiler, an easy to learn JS like syntax, strong static types, with amazing features like pattern matching and variant types. Until 2020 it was called "BuckleScript" and is closely related to ReasonML.

Ask HN: Interest in a Rust-Inspired Language Compiling to JavaScript?
As another commenter has already suggested, ReasonML has a lot of what you described here.
However, modern JS-oriented toolchain for ReasonML is called ReScript and you can learn more here: https://rescript-lang.org/

How does one write React apps in a purely functional style without making the entire codebase a mess?
ReScript (before BuckleScript) https://rescript-lang.org/ is a functional language that can also use OOP. Ideal for Javascript and Typescript projects, React and servers. It integrates perfectly with Javascript and Typescript code https://rescript-lang.org/docs/react/latest/introduction

Show HN: EdgeDB Cloud and 4.0 with FTS and Auth
Thank you!
We invited Gabriel because we think what he's building is pretty cool. It showcases so much about EdgeDB: its type system, data model, query language, composability, introspection, etc.
I'm not a ReScript user myself. What I know is that it's a functional programming language somewhat heavily inspired by OCaml. Their website goes into details [1]

Strong typing, a hill I'm willing to die on
You might want to look into ReScript (https://rescript-lang.org/). It has strong static typing with type inference, and it is very fast.

Building React Components Using Unions in TypeScript
This is because a “Tagged Union”, another word for TypeScript’s Discriminated Union, is a way to “tag which one is in use right now… we check the tag to see”. Just like when you’re shopping and check the tag of a piece of clothing to see what the price is, what size it is, or what material it’s made out of. Languages like ReScript compile many of their Unions (called Variants) to JavaScript Objects that have a tag property.
