We will remove the Fantomas Discord in favour of a channel on the #fsharp one: discord.com/channels/196... See you there!

Hey #fsharp what are your thoughts on github.com/fsprojects/f... ?

Hey #fsharp what are your thoughts on github.com/fsprojects/f... ?

F# folk, with @nojaf.com we've added support for generating llms.txt to the fsdocs tool that's widely used by the F# community. We'll release it soon but if you have a chance to take it for a spin before please do. github.com/fsprojects/F... #fsharp

F# folk, am working with @nojaf.com on a request from Nick Herchey to add support to fsdocs for "fsdocs convert" to easily convert between the nice literate programming formats F# supports - .fsx, .md, .ipynb, .tex Please take it for a spin and give feedback github.com/fsprojects/F...

Everyone voted right? github.com/fsprojects/f... #fsharp

I was on the latest episode of @deadcode.website to talk about @rescript-lang.org! If you've heard the name and wondered what's going on with it in 2025, give the episode a listen! shows.acast.com/dead-code/ep...

Dear #fsharp, we're asking again about a possible Fantomas default change: github.com/fsprojects/f... With 500+ downloads a day and only ~130 votes, we simply don’t have enough data yet. Absolute numbers matter before making such a decision.

Real talk: without a challenger like @bun.sh this would never have happened.

In the next version of our vscode plugin 🚀: github.com/rescript-lan...

Hi #fsharp we *might* consider changing a default in Fantomas: github.com/fsprojects/f... Please let us know what you think.

Been building a @rescript-lang.org MCP server lately, letting an LLM truly see a codebase. If you haven’t met ReScript before, this one’s still worth watching . It has a clear case of how localized MCP servers can lift developer tooling. youtube.com/watch?v=stIX... #rescript #mcp

ReScript 12.0.0 RC2 is out. Give it a spin and share feedback before the final release. github.com/rescript-lan...

PR merged, release unknown. Kinda a bummer. Dropped a vid with my thoughts: youtu.be/t3R-GnW-r9g?... (bonus: that thumbnail am I right 😉)

Waku v0.26.0 has just dropped. If you are new to Waku, it can help you try React Server Components. Read waku.gg and try `npm create waku@latest`. waku.gg/blog/removin... ⛩️

Latest @rescript-lang.org beta slaps hard! github.com/rescript-lan...

Help us test our new build system which comes enabled by default with the first ReScript v12 beta. npm create rescript-app@next forum.rescript-lang.org/t/ann-rescri...

Just dropped State of KAPLAY #5! A lot of improvements, new products and fun stuff, as always. Let us know what you think! kaplayjs.com/blog/sok5/ #javascript #gamedev

I made another video on @rescriptlang and @kaplayjs youtu.be/xxBPtmtvBTc?... Exploring the published bindings nojaf.com/rescript-kap..., a Flappy Bird clone and Rewatch!

It is hard to have patience in side quests of world domination plans

Sometimes I'm just such a thought leader

I made a video about @kaplayjs.com and @rescript-lang.org youtu.be/zUyrHXB_ImE Had a lot of fun with this!

Today, we’re announcing the preview release of ty, an extremely fast type checker and language server for Python, written in Rust. In early testing, it's 10x, 50x, even 100x faster than existing type checkers. (We've seen >600x speed-ups over Mypy in some real-world projects.)

Never use your default branch to send PRs in GitHub! Maintainers can't push to that branch, even though if you enabled "Maintainers are allowed to edit this pull request."

The editor tooling in #ReScript has immense potential. I'm very happy to be among the core contributors and learn from the best!

Working on preserving JSX in #ReScript output at the @rescript-lang.org retreat!

Upcoming ReScript (@rescript-lang.org) v12 move platform binaries into optional dependencies (e.g. rescript/linux-x64) To shrink the download & install size significantly! Download & Install size change: - Before: 67 MB | 197 MB - After: 15 MB | 48 MB (on a Linux x64 machine)

Does anyone know if #cursor follows links when indexing a remote llm.txt file? forum.cursor.com/t/does-doc-u...

I had a blast exploring @kaplayjs.com over the weekend! It's beautifully designed and offers so many amazing abstractions. Great stuff! Check it out: kaplayjs.com

I've been chatting a bit with Matthew lately, and his journey so far is very inspiring! I recommend tuning in if you're interested in learning how to contribute to #fsharp OSS!

This problem exists because a lot of reasonable individual decisions combined to form evil voltron

Discovery of the day: devtools logpoints. Instead of adding console.log directly in the code, you can add a logpoint in devtools (at least in Chrome). The brilliant @jec.fish has a video about this: youtu.be/JyHjoaUhAus. No more forgotten log lines! 🙌🏻

📢Hey #fsharp! Join us on Friday for another session. This time we'll be joined by @psfinaki.bsky.social we will discuss data serialization (aka ‘pickling’) in the F# compiler! More details amplifyingfsharp.io/sessions/202...

I wrote a blog post about using the React compiler with #rescript. You can check it out here: blog.nojaf.com/2025/03/23/r.... Things are going smoothly so far!

Alright, I made a thing: vanilla-jsx-to-rescript-jsx.web.app #rescript

We just landed a new (experimental) feature for v12 - nested record definitions! Records is a corner stone in ReScript. However, they can't be nested without explicit definitions. Until now! Will be especially useful for deeply nested records (like options objects) not intended to be reused.

My relationship with AST:

As an OSS maintainer, the ultimate move—just tell OP to send a PR. Either they do it, and you win, or they don’t, and the problem vanishes.

📢Hey #fsharp! Join us on Friday for another session. This time we'll be joined by Jimmy Byrd showing us how to use OpenTelemetry in our test suite!. More details amplifyingfsharp.io/sessions/202...

We are happy to announce that there will be another "ReScript Retreat" in 2025, once again in Vienna, Austria. Check out this new blogpost to get an idea what we did last year. rescript-lang.org/blog/retreats

Some thoughts on the TS compiler port to Go: - Overall I'm good here. - MS did talk to some folks in the community while working on this💪. This is good and should have had more emphasis. - They will have something at the end of the year 🤯. This might not be feasible with any other language.

Gleam v1.9.0 is out now! It's a big one! gleam.run/news/hello-e...

But have you heard of marimo? marimo.io

I wrote a post for the @rescript-lang.org blog! ReScript is awesome because you can drop it into any JavaScript project and use any JavaScript runtime. I'm currently working on a project using Deno and it works great!

Bun v1.2.3 - Fixes 128 bugs (addressing 349 👍) - Incredibly fast frontend dev server with hot reloading - Builtin routes in Bun.serve - Many Bun.SQL fixes - Wasm gets faster - Node compatibility improvements for napi & Buffer Thanks to 23 contributors! bun.sh/blog/release...

Moved to github.com/fable-compil... Thank you @jkone27.bsky.social and @Freymaurer #fsharp

@z-th.bsky.social has made an amazing job introducing #ReScript, go watch this deeply interesting video!

Much as I like #TypeScript, I think there's still plenty of room for competition. We need something that feels broadly like #JavaScript, but shaves away the corner cases, compiles faster, and just…flows…better. Could that be #ReScript? Let's find out… youtu.be/yKl2fSdnw7w
