👉 𝗞𝗼𝗶𝗻 𝗶𝘀 𝗽𝗿𝗶𝗺𝗮𝗿𝗶𝗹𝘆 𝗮 𝗗𝗲𝗽𝗲𝗻𝗱𝗲𝗻𝗰𝘆 𝗜𝗻𝗷𝗲𝗰𝘁𝗶𝗼𝗻 (𝗗𝗜) 𝗳𝗿𝗮𝗺𝗲𝘄𝗼𝗿𝗸, but it’s sometimes mistaken for a Service Locator due to how it handles dependencies. The key difference lies in how dependencies are provided:
💠 𝗗𝗲𝗽𝗲𝗻𝗱𝗲𝗻𝗰𝘆 𝗜𝗻𝗷𝗲𝗰𝘁𝗶𝗼𝗻 𝗺𝗲𝗮𝗻𝘀 𝗱𝗲𝗽𝗲𝗻𝗱𝗲𝗻𝗰𝗶𝗲𝘀 𝗮𝗿𝗲 𝗽𝗿𝗼𝘃𝗶𝗱𝗲𝗱 (𝗼𝗿 “𝗶𝗻𝗷𝗲𝗰𝘁𝗲𝗱”) by an external framework (like Koin) to the class that needs them, typically through constructor injection or field injection. Koin supports this approach by resolving and injecting dependencies automatically based on the definitions you provide in its modules.
💠 𝗦𝗲𝗿𝘃𝗶𝗰𝗲 𝗟𝗼𝗰𝗮𝘁𝗼𝗿 𝗶𝘀 𝗮 𝗽𝗮𝘁𝘁𝗲𝗿𝗻 𝘄𝗵𝗲𝗿𝗲 𝗼𝗯𝗷𝗲𝗰𝘁𝘀 𝗿𝗲𝗾𝘂𝗲𝘀𝘁 𝗱𝗲𝗽𝗲𝗻𝗱𝗲𝗻𝗰𝗶𝗲𝘀 𝗱𝗶𝗿𝗲𝗰𝘁𝗹𝘆 𝗳𝗿𝗼𝗺 𝗮 𝗰𝗲𝗻𝘁𝗿𝗮𝗹𝗶𝘇𝗲𝗱 𝗿𝗲𝗴𝗶𝘀𝘁𝗿𝘆 𝗼𝗿 𝗹𝗼𝗰𝗮𝘁𝗼𝗿 𝗮𝘁 𝗿𝘂𝗻𝘁𝗶𝗺𝗲. While Koin has similarities to this pattern (because you can explicitly request instances from Koin’s context), its primary mode of operation aligns more with Dependency Injection, as it manages object creation and wiring automatically for you.
✋ The confusion comes from the fact that Koin offers both injection and resolution on demand (via functions like get()), but its core mechanism follows the DI approach.
🔝 So, to clarify: 𝗞𝗼𝗶𝗻 𝗶𝘀 𝗮 𝗗𝗲𝗽𝗲𝗻𝗱𝗲𝗻𝗰𝘆 𝗜𝗻𝗷𝗲𝗰𝘁𝗶𝗼𝗻 𝗳𝗿𝗮𝗺𝗲𝘄𝗼𝗿𝗸, 𝗯𝘂𝘁 𝗶𝘁 𝗵𝗮𝘀 𝗳𝗲𝗮𝘁𝘂𝗿𝗲𝘀 𝘁𝗵𝗮𝘁 𝗰𝗮𝗻 𝗿𝗲𝘀𝗲𝗺𝗯𝗹𝗲 𝘁𝗵𝗲 𝗦𝗲𝗿𝘃𝗶𝗰𝗲 𝗟𝗼𝗰𝗮𝘁𝗼𝗿 𝗽𝗮𝘁𝘁𝗲𝗿𝗻. 🌟🚀
