Overview

Stop fighting runtime errors and start building systems that just work. Gleam for Production Systems is the practical guide to building fault-tolerant, scalable backends on the BEAM without the steep learning curve of Erlang or the dynamic typing pitfalls of Elixir. Whether you are migrating a legacy codebase or architecting a new microservice, this book gives you the type-safe blueprints you need to ship reliable software with confidence. Go beyond simple ""Hello World"" tutorials and dive deep into real-world production challenges. You will learn how to leverage the Actor Model for massive concurrency, design crash-proof supervision trees, and integrate seamlessly with existing Erlang and Elixir ecosystems. Through hands-on examples, you'll master modern tooling like Wisp for HTTP services, Mist for high-performance servers, and PostgreSQL for type-safe persistence. What You Will Learn: Solid Foundations: Master functional data structures, generics, and the use expression to write clean, maintainable code. Fearless Concurrency: Build scalable systems using Typed Actors and OTP abstractions without manual mutex management. Production-Ready Architecture: Implement Hexagonal Architecture, dependency injection, and comprehensive testing strategies (Unit, Property-Based, and Integration). Seamless Interop: Call Erlang/Elixir libraries directly and migrate incrementally without rewriting your entire stack. Ops & Deployment: Deploy robust releases to Fly.io/AWS and debug live systems using the Observer. Austyn Lawson is a backend systems engineer specializing in functional programming on the BEAM. He has spent years helping teams transition to type-safe architectures, minimizing technical debt while maximizing system uptime. Don't just write code-write systems that last. Scroll up and grab your copy today to master the future of type-safe backend development!
