This project compares different Dependency Injection frameworks by building the same example project for each framework:
Here are some useful links to get you started:
- Ktor Documentation
- Ktor GitHub page
- The Ktor Slack chat. You'll need to request an invite to join.
The domain of the project is fairly simple, and all modules use the same structuring:
com.example/
├── config/
│ └── [DI Configuration Files]
├── posts/
│ ├── Post.kt
│ ├── Repository.kt
│ └── Routes.kt
├── users/
│ ├── User.kt
│ ├── Repository.kt
│ └── Routes.kt
├── comments/
│ ├── Comment.kt
│ ├── Repository.kt
│ └── Routes.kt
└── Application.ktIf you inspect and compare all the files,
you will see that only the config module where the DI code resides differentiates.
The actual Ktor- and business-related code remains unchanged between all frameworks.
