Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Performance and memory impact of the @Singleton annotation in Dagger
There used to be a thing called "releasable references" which was that. It was removed, though: https://github.com/google/dagger/issues/1117

Dependency injection with AWS Lambdas in java
As said in the title, we will focus on the dependency inversion principle and one of its application : dependency injection. For production-ready applications, it would be better to rely on a framework and not implement its own container. For it, the java ecosystem have 3 frameworks available : Spring, Guice and Dagger.

Refactoring our Dependency Injection using Anvil
At Reddit, we use Dagger 2 for handling dependency injection (DI) in our Android application. As we’ve scaled the application over the years, we’ve accrued a bit of technical debt in how we have approached this problem.

Confusing. I initially thought someone ported the Dagger DI framework to Python: https://dagger.dev/

Multiplatform dependency injection libraries equivalent to Dagger/Anvil
I'm currently using Dagger and Anvil for my DI needs. It's been working really well, especially around what Anvil permits in terms of multibindings defined on the type declaration rather than in a module. For example:
-
Dagger 2.43 released with support for multiple instances of the same ViewModel using keys 🎉
Great job, I have been waiting for this feature/fix for a long time https://github.com/google/dagger/issues/2328

Refactoring our Dependency Injection using Anvil
Handling DI at scale can be a challenging task in avoiding circular dependencies, build bottlenecks, and poor developer experience. To solve these challenges and make it easier for our developers, we adopted Anvil, a compiler plugin that allows us to invert how developers wire, hook up dependencies and keep our implementations loosely coupled. However, before we get into the juicy details of using this new compiler plugin, let's talk about our current implementation and its problems that we are trying to solve.

Having both Dagger and Hilt at the same time? 🤔
I would recommend checking out Anvil for multi-module setup as it can provide an easier migration path than Hilt while also providing similar features.
-
Whetstone: A DI framework for Android that simplifies working with Dagger 2 using Anvil
In terms of of what Anvil is I'd really recommend reading the README It's a lot more flexible than Hilt and provides a code generation hook so if you have a codebase specific DI pattern you can also set that up to be auto-generated with a custom annotation if you desire.

Anvil, generating factories without kapt, and module structure.
Recently I've been looking into Anvil as an alternative to Dagger and realised that it can handily generate factories for you without kapt. That brings some exciting potential for build time improvement so I was eager to try it out. However very quickly I got stuck.

Toying with Kotlin's Context Receivers
Have you considered something like Dagger + Anvil (https://github.com/square/anvil) ? It works well enough that it gets out of your way. Is it doing insane things in the background at compilation time ? Absolutely. But it's worth it. And to save time in debug, you can shim in dagger-reflect to avoid the cost of having to run annotation processors.

N26 Path to Anvil
And finally, testing: Anvil offers a replace module feature that is handful to provide new dependencies during tests. For that, we create helper modules called testing and we provide fake dependencies of those replacing the production modules. Developers that include the testing in their test classpath can automatically interact with our testing utilities (or create their own, if required). To be completely honest here, it is more of an ongoing process.
