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.

Ask HN: What Happened to Elm?
> It sounds like you read my statement as "run the exact same code in node or OCaml" which I agree would have been very hard.
Hello! Indeed, I did misunderstand you. I agree that it was possible to share some parts of the code between Reason's JS target with BuckleScript, and native target with the stock OCaml compiler. I think a pretty reasonable number of people did that. Actually, it's still possible to this day even with ReScript e.g. https://github.com/aantron/dream/tree/master/example/w-fulls...
> Between the breaking changes and the general change in development philosophy...switching to the ReScript compiler for my project would have required nearly a complete rewrite.
There were perhaps a couple of minor breaking changes but can you explain why it would have required a near complete rewrite? I wasn't aware of anything major like that. ReScript even supported and as far as I know, to this day continues to support the old Reason syntax.

Functional Reactive Programming
> you might want to check out OCaml for general purpose programming
Any tips on backend frameworks to look at? I need to write a small websocket service for a side-project and have always wanted to try OCaml. I came across https://github.com/aantron/dream.

so people are making these
The framework I played around with for OCaml was called Dream: https://github.com/aantron/dream. I think it had built-in support for auth, but I didn't use it in what I was doing. I also barely scratched the surface of what it supported. On the whole, it seemed really nice though. The biggest issues I had were figuring out OCaml since I'd literally never used it before and figuring out how to make an HTTP call from within OCaml since the documentation can be iffy. Thankfully, Dream's documentation was actually reasonably good.

Dream – Tidy Web Framework for OCaml and ReasonML
Yes. OCaml + all of the 3 OCaml-to-JS compilers support OCaml syntax.
Dream itself demonstrates:
- Server and client both written in Reason, using ocamlc+Melange https://github.com/aantron/dream/tree/master/example/r-fulls...
That example could also have been written in OCaml syntax, because ocamlc (native) and Melange (JS) both support OCaml. However, Reason is nicer if you want to use React with JSX.
- Server and client both written in OCaml, using ocamlc+Js_of_ocaml https://github.com/aantron/dream/tree/master/example/w-fulls...
The remaining example uses Ocaml on the server and ReScript on the client, using the ReScript compiler. However, you could use OCaml on the client with the ReScript compiler. Just as with Melange, you would lose access to nice JSX syntax https://github.com/aantron/dream/tree/master/example/r-fulls...
It's definitely a lot and not user-friendly to have to decide between all these options, but the community is experimenting greatly right now... so it's good and bad, and that's how it is :/
As for Node.js, using ReScript syntax requires you to use Node.js on the native side, but that is the only coupling. If you write your native side in OCaml or Reason, you can compile it to native code with ocamlc (technically, ocamlopt is the internal command; nobody uses either one directly, but the build system calls them).

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.
