How to Restructure a Go CRUD API Using Packages for Better Maintainability

As Go projects grow beyond simple examples, keeping all code in a single main.go file makes applications harder to navigate and maintain. The solution is to reorganize code into separate packages, each with a distinct responsibility such as data models, HTTP handlers, and server startup. In this approach, a models package holds data structures like the Task struct, while a handlers package manages HTTP request logic, importing from models as needed. This pattern, known as separation of concerns, makes it easier to locate code, fix bugs, and add new features over time. The restructured project uses only Go's standard library, making it accessible to developers learning idiomatic Go project organization.
