Go Database Access: PostgreSQL CRUD for Web APIs

Connecting a backend service to a robust database is essential for any modern application. This course teaches you how to design, build, and structure a dedicated, reusable database package in Go. You will move beyond simple connection strings to implement safe, concurrent, and efficient data access logic using PostgreSQL, forming the foundation for scalable web APIs. What you'll learn: * Understand the fundamentals of relational database access in Go using the standard library and key packages. * Configure robust connection pooling and handle lifecycle management for PostgreSQL connections. * Implement foundational CRUD (Create, Read, Update, Delete) operations for common data models. * Apply context handling to database calls for proper timeout and cancellation control in concurrent APIs. * Practice structuring the database layer using interface definitions for improved testability and separation of concerns. * Master safe query execution, including prepared statements and avoiding common SQL injection vulnerabilities. The course begins by defining key database concepts and setting up the local PostgreSQL environment. We then systematically build out the connection manager and implement practical data access methods, ensuring every operation is structured for reliability and performance. This course is designed for new Go developers who understand basic Go syntax and want to learn how to integrate persistence into their web services. No prior advanced database experience is required.
