Gleam OTP in Practice

"Gleam OTP in Practice"
"Gleam OTP in Practice" is a comprehensive guide to building robust, maintainable, and highly concurrent systems using the Gleam programming language on the BEAM virtual machine. This book meticulously covers core concepts, starting from advanced Gleam syntax and the intricacies of static typing, through to the details of BEAM’s architecture and Gleam’s interplay with Erlang and Elixir. Readers are introduced to large-scale codebase structuring, powerful tooling techniques, performance profiling, and the nuanced balance between type safety and dynamic flexibility for industrial-grade applications.
Delving deep into OTP (Open Telecom Platform) principles and patterns, the book demonstrates how to design resilient systems with supervision trees, GenServer-like modules, advanced fault-tolerance, and hot code upgrades. It explores critical messaging models, including synchronous and asynchronous communication, distributed state synchronization, event-sourcing, and transactional consistency. Real-world operational concerns are addressed with strategies for testing, debugging, observability, security architectures, disaster recovery, and cloud-native deployment—all within the context of Gleam OTP.
Augmented by practical case studies from production systems, "Gleam OTP in Practice" provides actionable insights for scaling, distributed design, and integrating with both the BEAM ecosystem and external services. Whether you are migrating from Erlang or Elixir, or seeking a typed approach to resilient system development, this book is an indispensable resource for engineers aspiring to harness the full potential of Gleam OTP for modern fault-tolerant and scalable applications.
