Phoenix Unbound: Practical Elixir Web Development for Scalable, Real-Time Applications

Phoenix Unbound: Practical Elixir Web Development for Scalable, Real-Time Applications is a hands‑on guide for developers who want to exploit the power of Phoenix and the BEAM to build resilient, concurrent web systems. Beginning with Phoenix’s architecture and its Erlang lineage, the book clearly explains how requests flow through Endpoints, Plugs, and Controllers, and how OTP principles provide fault tolerance and predictable concurrency. You’ll learn pragmatic project organization, how to author custom middleware, and how to instrument applications with telemetry to gain deep operational visibility.

Moving into advanced territory, the book covers data modeling and persistence with Ecto—including multi‑tenant strategies, migrations, and working with diverse databases—and shows how to design secure, versioned APIs that support streaming and adhere to OpenAPI standards. Real‑time features are treated in depth: Phoenix Channels, Presence, event‑driven design, and secure communication patterns are all explained with practical examples. LiveView is presented as a first‑class option for building interactive, SEO‑friendly experiences that remain testable and performant.

Complementing the server side, the book provides modern front‑end integration techniques using Esbuild, TailwindCSS, and interoperability patterns with popular JavaScript frameworks. It also addresses the full lifecycle of production systems: testing, observability, security best practices, CI/CD, error monitoring, chaos testing, containerization, and scalable cloud deployments. Whether you’re architecting APIs, real‑time systems, or dynamic interfaces, Phoenix Unbound delivers the patterns, tools, and operational practices to build scalable, maintainable applications with confidence.
