[ANN] Sunset of legacy build system

Dear community, For the next major release our plan is to sunset the rescript-legacy build system (internally named bsb) and completely replace it with the new build system announced in rescript 12. ...

ReScript v12 just got released with a bunch of goodies, so now would definitely be a good time to try it if you wanted to. It's in a better state than ever now.

ReScript 12 is here! A major step toward a leaner, faster, simpler toolchain. This release refines the language and embraces ReScript’s own identity. Blog: rescript-lang.org/blog/release... Notes: github.com/rescript-lan... Huge thanks to everyone who helped move ReScript forward.

Ping me whenever you're taking a look at it. At its core it's essentially "just" producing HTML instead of the DOM creation/update instructions I'm guessing you're producing now, for a single initial render. Then there's hydration of course, which is a bit harder. But lots of prior art.

Have you thought anything about potential support for SSR?

Amazing work by everyone involved in building Rewatch! So excited this will be released in v12. It lays the foundation for ReScript going forward, and enables a bunch of cool things you'll hear more about post v12.

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

I've used it server side only, but still using `relay-runtime` to do the actual querying etc. But without `react-relay` and any client side JS. So I guess it does have the client cache, but server side, and it's reset between each server request, like a dataloader.

Great post! One of the biggest benefits to me is it forces you to actually understand what you're doing, which I think compounds like crazy over the years.

Gabriel Nordeborn @z-th.bsky.social · 09/10/2025

Got it! So it's about untangling dependencies essentially. I can see the value in that for sure.

010

Gabriel Nordeborn @z-th.bsky.social · 09/10/2025

What would you say are the big benefits compared to just using context + functions operating on context directly?

110

Gabriel Nordeborn @z-th.bsky.social · 22/07/2025

There's also an option to turn it on automatically for all mutations that return unions. This makes the pattern of returning a union of success/explicit errors easier and more ergonomic. Will be in the next RescriptRelay version!

010

Gabriel Nordeborn @z-th.bsky.social · 22/07/2025

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.

Thank you, that's very kind! 😀 I use it for a ton of things, especially paired with github.com/zth/pgtyped-.... For many sorts of projects I find it strikes the right balance between complexity and capabilities.

Yup! There's also inlay hints you could experiment with. It's similar, but for identifiers/arguments etc.

Gabriel Nordeborn @z-th.bsky.social · 23/06/2025

Yeah this is invaluable when working a lot with inference! You can enable the same for the ReScript LSP btw if you're using ReScript. It's in the extension settings.

That's great, and exactly what we need - someone who actually knows the tech. Looking forward to it!

Gabriel Nordeborn @z-th.bsky.social · 05/06/2025

Yup! Making a good integration requires someone who really knows the stack well, and is invested in using it. Will never get good results otherwise.

Gabriel Nordeborn @z-th.bsky.social · 05/06/2025

Yeah, keep us posted and hit us up! Start a forum thread and we'd be very happy to support you exploring. Do you know Svelte well?

Gabriel Nordeborn @z-th.bsky.social · 03/06/2025

The caveat is that we'd need a "champion" for it that experiments and is invested in using it + making it work well. Then we'd very much be up for investing into it. Maybe not what you had in mind, but let us know if you'd be interested! 😀

FWIW, there's interest in making the Svelte-and-ReScript story a great one from us: forum.rescript-lang.org/t/use-rescri... In short, if there's sufficient interest one could most definitely make ReScript work in <script type="res"> tags in Svelte, and get tooling working etc.

There’s also the possibility of also writing the ReScript found in Svelte script tags to actual files, kind of like you describe @hellos3b. Lots of possibilities. We can figure out a nice approach fo...

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.

But since we're gradually moving away from the OCaml AST to our own AST it's possible for us to first-class this in the AST if we want to, and if the experiment proves fruitful. Side note - nested definitions has always been possible with structural objects, but not with records. 2/2

060

Gabriel Nordeborn @z-th.bsky.social · 22/03/2025

Yes, it's inherited from OCaml. But I'm sure there's good reason for it looking that way (one type definition per level). What we've been bothered by is the ergonomics primarily. This first implementation still uses individual records for each level, just hides it to the user in practice. 1/2

150

Gabriel Nordeborn @z-th.bsky.social · 20/03/2025

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!

Gabriel Nordeborn @z-th.bsky.social · 17/03/2025

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