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.

Melange for React devs book, alpha release
Hey HN, at Ahrefs we have been working on an online book that hopefully helps React developers get up and running with Melange, an OCaml to JavaScript compiler. You can read more about Melange here: https://melange.re/.
There are still a few chapters that we'd like to add before considering it "complete", but it might be already helpful for some folks out there, that's why we decided to publish it early.
The book uses Reason syntax to implement React components using ReasonReact components. You can read more about both in:

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.

Earning the privilege to work on unoriginal problems
This tracks with how I've seen "normal" languages converge on similar, flawed imitations of better type systems through tools and repurposed syntax. Thank you for confirming.
Do you have any recommendations or warnings regarding general languages which reach in the opposite direction? Reason[1] and F#[2] are both examples: they attach pre-existing ecosystems and compile-for-$PLATFORM tools to OCaml-like typing.
OCaml itself is also intriguing for personal projects. However, I'm worried the "GPL" in its standard library's LGPL license might scare people despite both the linking exception and Jane Street's MIT alternative.

Melange 1.0: Compile OCaml / ReasonML to JavaScript
ReasonML purely as a syntax layer on top of OCaml is still being updated and released[1]. Incidentally, I'm one of the maintainers of that project too :-)
With this Melange release, we're hoping to somewhat revive ReasonML and channel some folks back to the community from the perspective of a vertically integrated platform that has seen major investment in the past few years.

Why not use https://reasonml.github.io/ instead? Or just use Typescript?

Tagging OCaml packages
If you are using the dune build system, add the tag(s) to your dune-project file's package stanza. E.g.:
-
NextJS, the App Router and ReasonReact
One way to get around this is to modify the api/dune file with (include_subdirs qualified); this means that every subdirectory of api/ can be referenced by module namespacing and we don't have to write dune files for every route (or pages) folder. However, the OCaml LSP does not like it and red squiggles will show up in the editor (although the app with still compile without errors). Trying to develop the app knowing those red squiggles cannot be vanquished would drive me nuts, so instead of using (include_subdirs qualified) I just wrote dune files for every route (and page) which gets rid of the red squiggles.

Ask HN: Programs that saved you 100 hours? (2022 edition)
Dune (https://dune.build/) is the preeminent build tool for OCaml development. I don't love its input syntax (s-expressions), and I sometimes miss the ability to write high-level functions to reduce boilerplate (especially for unit tests), but it always gets the dependencies right, and it's fast. This is in stark contrast to some of my experiences with various other build systems, and I am super happy that the default option for OCaml build systems is so good.

How to print anything in OCaml
ONE of the big benefits of OCaml is its powerful REPL (also called the toplevel), the interactive command-line utility where you can load modules, type in and execute code, and see its results. The modern REPL, utop, has powerful auto-completion and integration with the build system dune, which enables productive workflows like loading an entire project's libraries in the REPL and interactively exploring them.
