In part 3 of this series, we unlock the power of Dependency Injection in our Go application! We delve into structuring our code for greater flexibility and maintainability. Discover why rolling your own DI can be more beneficial than relying on frameworks.
Continuing from part 1, we are expanding our simple "Hello World" project by making it configurable. We introduce environment-based configuration along with .env files and the godotenv package. We then show how to automate loading our settings into structs with reflection and struct tags. Finally, we will cover splitting our configuration by concern for a cleaner, more scalable design.
