Persistent Storage with JSON in Go

Managing data persistence without the overhead of massive database engines is a vital skill for building lightweight, efficient services. This text-based course guides you through the foundational concepts of data serialization, file handling, and network communication in Go. You will start with the absolute basics of Go structures, encoding, and decoding before assembling a fully functional URL shortener utility. By reading through clear, step-by-step explanations and structured code files, you will understand how to safely write data to disk, read it back on startup, and expose your service over Remote Procedure Calls (RPC). What you will learn: - Understand JSON serialization and deserialization using Go's standard library. - Design a robust persistent storage engine utilizing flat JSON files. - Implement concurrent-safe data operations using mutexes to prevent race conditions. - Configure Go's RPC package to enable distributed communication between services. - Apply modern Go practices including structured logging and proper error handling. The course starts with essential definitions of persistence and serialization, moves into file system interactions, and concludes with building a network-accessible service. This program is designed for beginner to intermediate Go developers who want to transition from in-memory applications to persistent, distributed systems. No prior database experience is required.
