Dagger2 VS katana

There used to be a thing called "releasable references" which was that. It was removed, though: https://github.com/google/dagger/issues/1117

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.

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/

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:

Great job, I have been waiting for this feature/fix for a long time https://github.com/google/dagger/issues/2328

Dagger

Using a few different methods. Pulling the sites I'm using Puppeteer and Katana (https://github.com/projectdiscovery/katana). To process and extract the information is tricky, most websites selling things put time into their metadata; this does make it easier. Additionally, a lot of the larger stores have common patterns between them. Failing all of this, I trained a Tensor flow model to understand how to read product pages. However, it's far from perfect and a journey of continual improvement.

Anyway, check out katana https://github.com/projectdiscovery/katana
