#rescript — Public Fediverse posts

I wish so badly that #ReScript had an equivalent to early returns, #Rust `?` syntax, or #Kotlin `.?` syntax. So much nesting. Even #OCaml allows for dumb helper functions for `Result.bind`

📝 New blog post: making a football analytics site

I built a static Super Lig analytics site with a Python scraper, an embedded SQLite database, a ReScript frontend, and a mildly annoying GitHub Pages deployment puzzle.

📝 New blog post: ReScript vs Gleam: is it worth writing your frontend in a typesafe functional language?

I rewrote my portfolio site in both ReScript and Gleam to find out which one actually delivers on the promise of less code, more safety, and better developer experience.

ReScript 12 ra mắt hệ thống build mới, xây dựng bằng Rust, hỗ trợ theo dõi phụ thuộc thông minh, build tăng lượng nhanh hơn và hỗ trợ monorepo. Hệ thống này giảm công việc dư thừa, tăng độ chính xác khi rebuild và tối ưu hóa cấu hình đa package.

Night 2 of #Rescript published my first Rescript binding to immutable js

Q: Why do this if you already have Base.Set.t in the core libs?
A: immutable js has toJS() and fromJS() which allows you to deep convert into/out of immutable classes to standard JavaScript, something I haven’t seen anywhere else.

Is #ReScript the future of #javascipt? A typed subset of JavaScript.

#Typescript is great but not all love it.

From the docs: "ReScript is the language for folks who don't necessarily love JavaScript, but who still acknowledge its importance."

https://rescript-lang.org

As much as I like #TypeScript, I think there's still plenty of innovation left in the world of compiles-to-JavaScript languages. We need something that feels broadly like JavaScript, but shaves away the corner cases, makes everything immutable by default, and just...flows...better. And #ReScript might well be that language. Let's find out...

Hey scripting folks! I'm trying to get started with rescript-react-native and I'm having a bit of trouble, so I put a hundred dollars on it.

Come take my money!

#bounty #bugbounty #javascript #react #reactJS #reactNative #rescript #rescriptReactNative

thank you async await for saving me from #JavaScript callback hell

thank you #ReScript for saving me from typeless no-trail-of-what's-returning-what hell

I just followed a bunch of type errors and ended up with a beautiful chain of async calls that execute in the proper order it's so cute

@rauschma What is your opinion of #ReScript (https://rescript-lang.org/)? It has somewhat an #OCaml heritage via #ReasonML

Edit: Just looked at the source for Grain; it’s mostly ReasonML!

I don't mind breaking changes from time to time, but they really should have fully implemented import maps and written detailed documentation on the main site about how to upgrade *before* deprecating es6-global.

#ReScript

I am adding the #ReScript language server to #nixpkgs. 👍 this PR to get it merged https://github.com/NixOS/nixpkgs/pull/348121

Hey, #Nix friends! I am working on making my first contribution to #nixpkgs, and I have a question:

The package I'm working on adding is an executable npm package, specifically the #ReScript language server.

I wouldn't mind taking on some responsibility for making sure that package is up to date, but it seems like the whole "maintainer" bit described here:

https://github.com/NixOS/nixpkgs/blob/master/maintainers/README.md#how-to-become-a-maintainer

...isn't actually applicable to npm packages b/c they're handled automatically. Do I have that right?

"ReScript: Rust like features for JavaScript - DEV Community" https://dev.to/jderochervlk/rescript-rust-like-features-for-javascript-27ig #rescript #javascript

If a #JavaScript #programmer is compelled to trade up to #TypeScript, then he ought to take one more step to #ReScript and, from thence, to #Reason. With Reason in hand, he wields the full power of #OCaml.

JavaScript → TypeScript → ReScript → Reason

During my parental leave I learned two new programming languages. One of them was #ReScript and I wrote up my impressions of it: https://snarky.ca/my-impressions-of-rescript/ .

At an emotional level, I adore #Python 3, #TypeScript 5, and #ReScript 11. But at an intellectual level, ....🤷‍♂️

Don't expect easy-to-fix bug in JS/TS while aiming to have smallest bundle size. It just too hard!

The worst part is closure compiler can't catch up with latest ES spec 😮‍💨

I place my hope on #ReScript but it doesn't emit sourcemap and there's no sign they're working on it 😱

#webdev #javascript #typescript

I wonder how #melange `[@mel.uncurry]` compare with #rescript uncurry mode 🤔

Of late, there have been numerous good-hearted attempts at creating #webdev #DSL, both internal and external varieties. But just about every one of them get tripped up by the disjointed nature of the current web technologies and, soon, they degenerate into JavaScript mayhem.

When a #programming language obliges the #programmer to handcraft asynchronous communication, thread management, code-download splitting, server-side pre-rendering, session management, authentication, authorisation, transport encryption, data caching, data format conversion, content validation, message queues, storage optimisation, and myriad other system-level facilities, this language, by definition, is not a DSL.

At present, the only webdev DSL that I admire is #Elm, which is a Webskell. And I like #ReScript, not because it's in anyway a DSL, but because it's OCaml.

A different, but related, problem is this: modern business programmers confuse enterprise application implementation with systems programming. And modern business executives confuse enterprise application user interface with marketing material. This is ineffective and unproductive.

So I need to create empty folder `node_modules/rescript/`to make `rescript-editor-analysis.exe` to works 😥

#rescript jouney
Yep, I need to include their stdlib too

#rescript journey 🥷
So ninja v1.11.1 didn't work on rescript but ninja v1.9.0 works just fine. I wonder if it also works on Kawasaki Ninja 🚲

#rescript journey
Seems fun to write my own build system using `xmake` or `knit` then use `bsc` as compiler 🤔

#rescript and #melange not yet available in #nixpkgs 🤔

Mam ochotę popisać znów trochę w #ReScript, ale nie jakieś zabawkowe projekty do kosza, tylko coś użytecznego…

Jakieś sugestie?

#JavaScript

anyway, the last bit from my notes, is a bit more personal:

I’ve always been harping, for years, on how #OCaml and #JavaScript VMs are just such a surprisingly-fantastic, low-impedance match (see the whole #Melange, #BuckleScript, #ReScript, category — they're _fantastic_ to use in practice); …

but now i’m learning that Wasm is … basically OCaml’s semantics, EVEN MORE DIRECTLY, in a bunch of cases, lmao.

I love everything about #rescript except I don't know how much longer I can deal with the constant #Ninja issues.

Updated a program that I had written a couple of years ago in #ReScript (https://rescript-lang.org). The language has changed a bit. Still a good choice.

@musicmatze If you like Rust and you're thinking of using a JS-compiling language, you might have a look at #ReScript. It's a functional language with good pattern matching syntax, very similar to Rust.

Made a #FunctionalProgramming #alignmentchart for funsies. Heated debate is welcome (I might mute the thread though) 😆​

Just realized that, with all the other stuff I have going on, I haven’t checked in on the #ReScript world in a long time. (https://rescript-lang.org/)

I am pleased to announce the next event in the #FPWebConf series, this Saturday (8 July) -

#Rescript meetup at Juspay offices, Bangalore, where Shiva Nandan will speak about how Juspay uses Rescript in production.

@wfaler #ReasonML looked interesting - then kinda forked to #ReScript (https://rescript-lang.org - which is just the buckle script layer) and it’s direction got confusing from the outside.

Maybe I should just start looking at #FSharp and .NET

#introduction

👋 Hello everyone from Brooklyn, NY! In my day job I'm a full-stack web developer using #nodejs #typescript #react building project management tools for fashion designers.

In the 🌃 , I tinker with #rust and #rescript. I'm trying to also learn about infrastructure, so playing around with #pulumi, #nomad, #traefik on #Hetzner

✊
Radical #anarchist #dad #musician #youthliberation #blacklivesmatter

@andrioid current stack is #rescript and #fsharp with some @darklang, #python, #bash and #javascript. I wish more was in Darklang!

I'm surprised at how little activity there is on the #rescript tag even relative to other small languages like Idris.

More of you should try #ReScript! It's a delightful little #javascript-compiling #functional #OCaml for those of us who like C-like visible delimiting characters!
