Learn Go with Pocket-Sized Projects

Pocket-size projects, modular and versatile skills! Take your Go programming capabilities to the next level with 11 engaging applications. Learn Go with Pocket-Sized Projects teaches some of the most important skills of Go programming—including Go’s unique idiomatic syntax—all through building fun and useful apps and games. Each project is fully working, simple to write, and easy to scale-up to full-size Go applications. In Learn Go with Pocket-Sized Projects you’ll build: • A Wordle-alike game • A currency converter application • A habit-tracking application • A book digest application • A maze-solving algorithm • A microcontroller-based traffic lights program • …and more! Each small, self-contained project in Learn Go with Pocket-Sized Projects introduces important practical skills, including ensuring that your code is thoroughly tested and documented! You’ll make architectural decisions for your projects and organize your code in a maintainable way. Work your way through, and you’ll be able to utilize Go for everything from server-side applications to low-level systems programming. Foreword by Ron Evans.

About the technology There’s no more satisfying way to learn a programming language than by building your own projects! Whether you’re coming from another language or taking your next steps in Go, these eleven projects will get you working hands on faster than you can type “Bonjour le monde.” About the book Learn Go with Pocket-Sized Projects introduces the most important features, concepts and techniques of the Go programming language. You’ll learn hands on as you build fun mini projects including a Wordle clone you can run as a web service and a maze solver that uses goroutines. Along the way, you’ll explore a wide range of topics, including Go’s unique approach to interfaces, concurrency, REST and gRPC microservice APIs, and more. What's inside • Concurrency with goroutines • A habit tracker using gRPC and HTML templates • Deploying a secure web service • A microcontroller-based traffic lights program using TinyGo About the reader For beginners with Go or another programming language. About the author Aliénor Latour, Donia Chaiehloudj, and Pascal Bertrand are experienced developers with a passion for Go and excellence in programming. Table of Contents 1 MeetGo 2 Hello, earth!
