Just landed support in RescriptRelay for a new directive called @exhaustive. Putting this on a field or fragment definition that's a union will force you to select all members explicitly of that union. Great for evolving your schema and being notified of new code paths, just like with enums.

I just stumbled on @z-th.bsky.social’s ResX and audibly said “how the fuck is he doing that” so many times when reading the docs Genuinely magical, I’m gonna try it out tonight and am super excited to. The HTMX handlers are just… I don’t understand how that’s possible lol.

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!

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

Good morning! We are currently kicking off this year's ReScript Retreat with a talk about editor tooling by @z-th.bsky.social and @nojaf.com.

Heading out to the @rescript-lang.org contributors retreat! Very excited.

After all these years, I still love Relay and GraphQL and the benefits they bring. Talk about standing the test of time, at least for me. I've used both since they were open sourced almost 10 years ago. They're not without issues ofc, but they answer all the big issues in UI development for me.

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

This one is really exciting to me because it solves a very real issue - using records for deeply nested objects is a big pain - hard to both define and read the types needed. Looking forward to using it in v12!

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.

This is going to be a blast, can't wait! Last one was absolutely fantastic.

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

I had the great opportunity to be on Developer Voices to talk a bit about ReScript!

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

This is going to make a few use cases, like when dealing with one-off nested shapes, much easier.

Records are powerful, but you need explicit definitions for them. We're experimenting with allowing inline record definitions nested inside a record type definition. This will make some of the common use cases for records more ergonomic.

Explored options for my new personal project, from more common ones like Phoenix Liveview, to niche ones like Moonbit / Swift fullstack on Spin, Gleam fullstack with Wisp and Lustre, etc... Looks like I'm ending up with ReScript and @z-th.bsky.social stuffs like Resgraph, ReScriptRelay and pgtyped 😅

ReScript @rescript-lang.org · 2y ago

The new dot completion also works for objects. Objects are structurally typed, doesn't need a type definition, and are quite useful in some scenarios. Completion for object fields will be more ergonomic and get better discoverability with this addition.

ReScript @rescript-lang.org · 2y ago

With the new dot completion enhancements in our editor tooling you'll now get completions from the Option module when autocompleting on a record field that's an optional value, instead of just no completions like before.

ReScript@rescript-lang.org · 2y ago

This is one of the more exciting features I've worked on for the editor in a while. Pragmatic, useful and ergonomic. Just what we should be focusing on. I'm really proud of what we're doing! I look forward to 2025, which I think is going to be a big year for ReScript.

Happy new year! We're almost ready to release an exciting editor feature - dot completion everywhere! "." will now trigger completions for more than just record fields. Example: you'll get completions for pipeable functions from the module of that type. Examples and videos ⬇️
