ReScript 10.0

This page summarizes the projects mentioned and recommended in the original post on

Our great sponsors
  • WorkOS - The modern API for authentication & user identity.
  • Onboard AI - ChatGPT with full context of any GitHub repo.
  • InfluxDB - Power Real-Time Data Analytics at Scale
  • genType

    Auto generation of idiomatic bindings between Reason and JavaScript: either vanilla or typed with TypeScript/FlowType.

    They discuss this in their docs.

    Seems like a type system for Javascript, built with a differing set of opinions than Typescript.

    Looks like they also offer some form of TS interop:

  • reason

    Simple, fast & type safe code that leverages the JavaScript & OCaml ecosystems

    IT's a META project based/fork of ReasonML ( They are ocalm dialects thats compile to Javascript. Advantage vs Typescript is a strict type system.

  • WorkOS

    The modern API for authentication & user identity. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • proposal-type-annotations

    ECMAScript proposal for type syntax that is erased - Stage 1

    > I even don't understand why browser don't start to work on supporting it directly

  • nanoid

    A tiny (124 bytes), secure, URL-friendly, unique string ID generator for JavaScript

    I don't understand why ReScript is trying to sell itself as a language for React. React is already "kind of" functional, has a rich JS/TS ecosystem and there are fantastic alternatives such as Elm.

    I think this would have huge potential in the backend space if it had good interop with Node.js and TS, with perhaps a functional framework similar to Elixir's Phoenix. Elixir proved it can have fantastic integration with Erlang.

    * More robust applications with the Result type

    * An actual integer type (for 64-bit database keys, Prisma uses BigInt)

    * Finite state machines for stateful logic, games, websockets (enums and a sound type system)

    * Benefit from the JS-centric serverless ecosystem

    We've already been "compiling" or "transpiling" JS for years, most website JS is unreadable.

    In its current state, I don't even want to imagine what it would be like to set this up alongside ESM, TS, Prettier, ESLint, Jest, Storybook, ESBuild, Vite, (insert cool tool here). I've already spent literal days trying to setup a "modern" Node.js project, only to give up and go back to CJS for simplicity and import older non-ESM versions of packages[1], wish I wasn't using Node.js, then remember how many things I miss from JS when trialing another language.


  • Scala.js

    Scala.js, the Scala to JavaScript compiler

    I don't see anything in ReScript that hasn't been already covered by

    Am I missing something?
