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.

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.

Looks like a massive perf improvement could land on the playground! Great job @hyeseong.kim !
Experimented with wasm_of_ocaml build for

compiler
It gave almost 3x faster performance than the original js_of_ocaml build! 🔥

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!

@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…

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.

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.

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.

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.
