Set up and run custom ETL (Extract, Transform, Load) tasks. Kargaru-ETL is a user-friendly, cross-platform Electron application designed to utilize the RxJS-ETL library. RxJS-ETL is a modular platform built with RxJS observables that allow developers to create stream-based ETL pipelines. The platform offers additional capabilities such as buffering, bulk insertions, notifications upon task completion, job scheduling, and the establishment of task dependencies. Those who wish for or need a more visual and guided experience using RxJS-ETL can run Kangaru-ETL to import and export files, connect to databases, write transformation scripts, and set up a queue of scheduled ETL jobs.

QUESTION
I'm very new to IoC idea and I'm trying to jump over the Service Locator pattern. I chose the Kangaru implementation. Suppose I want to use Audio and Logger services in different places of my app. What I have now:
...ANSWER
Answered 2021-Jun-06 at 02:01The main advantages of using a library to handle dependency injection is:
- The automation of boilerplate code
- Having a central place that contains the instance about the current context
Using a dependency injection container, you have that single entity that contains the all the instances. It can be tempting to send that thing everywhere since you'll have the whole context available, but I would advise against.
In the kangaru documentation, I added this in the guidelines:
This library is a great tool to minimize coupling, but coupling with this library is still coupling.
So for example, if void f();
(as a free function) needs the logger, then it should be passed as parameter.
