Getting Started with ReasonML and React Native
Article Summary
ReasonML brings OCaml's type safety to React Native, but getting started requires navigating a new syntax and toolchain. Callstack breaks down the setup.
This guide from Callstack walks through integrating ReasonML with React Native projects. ReasonML is a syntax layer over OCaml that compiles to JavaScript, offering stronger type guarantees than TypeScript while maintaining React compatibility.
Key Takeaways
- ReasonML provides OCaml's type system with JavaScript interop
- Setup requires BuckleScript compiler and reason-react bindings
- Type inference catches errors at compile time, not runtime
- Syntax differs from JavaScript but compiles to readable JS
Critical Insight
ReasonML adds industrial-strength type safety to React Native through OCaml's proven type system, trading familiar syntax for stronger compile-time guarantees.
