Ruchy WebAssembly & REPL Mastery

Production-Ready WebAssembly Development

A comprehensive guide to building high-performance, cross-platform applications with Ruchy’s native WebAssembly compilation

About This Book

This book teaches WASM-first development using Ruchy v2.1.0’s native WebAssembly compilation capabilities. Every example compiles to production-ready WASM modules that deploy instantly to:

  • Browser Applications (JavaScript interop)
  • Node.js Server Modules (high-performance backends)
  • Cloudflare Workers (edge computing)
  • AWS Lambda (serverless functions)
  • Vercel (JAMstack deployment)
  • Deno (modern runtime integration)

What Makes This Different

WASM-First Approach: Write once in Ruchy, deploy everywhere as optimized WebAssembly.

Production Testing: Every code example is validated across all deployment platforms.

Quality Gates: All modules pass security validation, performance benchmarks, and quality scoring.

Test-Driven Learning: TDD methodology with REPL validation for every concept.
