Go App Development: Building and Seeding a Phone Book Application

Every real-world application needs realistic data to test its performance and search capabilities under pressure. Building and testing software with manual entries limits your ability to find bugs and optimize search algorithms. In this written course, you will learn how to design a Go-based phone book application from scratch and implement robust data-generation techniques to populate it with thousands of mock records. You will gain a solid understanding of how data structures affect search speed and how to write clean, testable Go code. What you'll learn: - Understand foundational Go concepts including structs, slices, and maps for managing application state. - Generate realistic random names and phone numbers to seed your application database. - Implement efficient search algorithms to quickly locate records within large datasets. - Write basic unit tests in Go to ensure your data generation and search logic work reliably. - Apply performance best practices such as memory pre-allocation for slices. The course starts with fundamental Go syntax and data structures before guiding you through the step-by-step logic of mock data generation, search optimization, and testing. This course is designed for beginners who have a basic understanding of programming concepts and want to practice building practical Go applications. No advanced Go experience is required.
