bolt-python VS Dependency Injector

This post will follow and extend the example from slackapi/bolt-python and manage infrasture as code it using AWS CDK typescript.

I started building this framework a couple of years ago because I found no easy existing solution to build Slack bots that can be composed from/organized into plugins. Existing libraries like Bolt make it pretty easy to develop Slack bots, but hard to organize and scale the code base of your bot. I was also missing some crucial features such as scheduling actions for your bot. So I wrote my own framework!

Looks like there's an official guide in the works: https://github.com/slackapi/bolt-python/pull/441

Nothing to do with the nature of the language, but with the nature of the program.

If you're writing a few line script, you don't need a DI container. Once your program gets large, it becomes extremely messy without one. It's no surprise projects like [1] exist.

Totally agree with this. And I’ve found this pattern pairs really well with https://python-dependency-injector.ets-labs.org/

dependency_injector: https://github.com/ets-labs/python-dependency-injector

As projects continue to grow, its recommended to utilise a dependency injection framework to “inject” these dependencies, such as Dependency Injector, to inject dependency arguments automatically ✨.

One approach is to pass this config as a variable to every class it is required, which I dont prefer. Another option is to annotate the config class as singleton and create the config object at every place where I need them. I also came across this library called Dependency_Injector. https://python-dependency-injector.ets-labs.org/ This seems a bit heavy weight for my use case though. I am looking forward to know how other solve this problem

Dependency Injector

dependency-injector (docs) is python library that provides a framework which enables you to implement DI and IoC in Python.
