Systems Programming with Zig: Build Real Tools with No Hidden Cost

Build efficient systems software with the Zig programming language by creating UNIX tools, network services, asynchronous applications, and high-performance servers. Key Features Build real-world systems software and UNIX programming tools through practical Zig projects Develop network programming skills through TCP, UDP, HTTP services, concurrent applications, and CLI tools Master memory management, I/O, and systems-level design with the Zig programming language Book DescriptionBuild reliable systems software with Zig through a project-driven approach focused on practical engineering challenges. Guided by UNIX systems engineer & bestselling author Mihalis Tsoukalos, you will learn modern systems programming techniques while creating production-ready applications, UNIX tools, & network services. This book takes you from essential UNIX tooling and build infrastructure to advanced topics such as direct memory access, binary formats, filesystem monitoring, networking, concurrency, asynchronous I/O, & database integration. Through hands-on projects, you will create command-line utilities, TCP and UDP services, HTTP applications, file indexing tools, cache servers, & a domain-specific language interpreter that combines memory management, comptime metaprogramming, parsing, evaluation, & error handling. Each chapter demonstrates how Zig features solve practical systems programming problems. You will work with memory management, process control, synchronization primitives, event-driven architectures, SQLite integration, protocol design, & performance-focused data structures while learning the reasoning behind key engineering decisions. By the end of this book, you will be able to build efficient and maintainable systems software in Zig & confidently apply the language to production projects.What you will learn Build production-ready UNIX command-line tools with Zig Develop TCP, UDP, and HTTP network services and applications Apply systems programming techniques to memory, filesystems, and process management Manage memory and binary data safely and efficiently Implement multithreading, synchronization, and concurrent systems Create asynchronous I/O and event-driven network applications Integrate SQLite into real-world Zig applications Design and build a domain-specific language using parsing and comptime techniques Who this book is forSoftware developers, systems programmers, UNIX systems engineers, and backend engineers who already understand Zig fundamentals and want to build production-ready systems software. Familiarity with programming concepts and experience using languages such as C, C++, Rust, Go, or Python will help you get the most from this book.
