The article provides a detailed guide on integrating SQLite with Golang to build an activity tracker that persists data using the database/sql package, ensuring workouts are not lost even if the service goes down. It covers setting up the development environment, installing necessary tools like SQLite3 and sqlite-utils, and creating a database schema either manually or using utilities for ease. The tutorial further explains the nuances of handling data types in SQLite, using the Golang SQL repository for database operations, and the importance of prepared statements for optimizing SQL queries. Testing methods and integration with Earthly for containerized builds are discussed, alongside challenges like the need for a GCC compiler for building the SQLite driver. The author reflects on the learning process, highlighting key insights into database handling and encouraging the use of tools like Earthly for efficient Golang builds, while also teasing future explorations into gRPC and protocol buffers.
