Announcing ReScript 12 | ReScript Blog ReScript 12 arrives with a redesigned build toolchain, a modular runtime, and a wave of ergonomic language features.

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.

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)

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.

What can I do with ReScript? | ReScript Blog Can I use Vite, or Next.js? Is it only for React? Can I use Node or Deno?

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!
