 ## Differences to Micronaut DI (https://docs.micronaut.io/latest/guide/index.html#ioc)
 
 - DInject generates source code rather that bytecode
 - DInject generates construction order at compile time
 - DInject is aiming to be a `Library only` (so a DI library and that's it without any dependencies)
-- DInject is expected to stay a lot smaller with minimal dependencies 
+- DInject is expected to stay a lot smaller with minimal dependencies
 - DInject is expected to be a lot faster (due to the pre-ordering of construction in generated code)
 
 ## Differences to Spring DI (https://docs.spring.io/spring-framework/docs/current/spring-framework-reference/core.html)
 
 - DInject only has Singleton scope
 - DInject doesn't yet have support for something like `@Value`
 - DInject provides similar DI features but with code generation via APT
