Not really clear why someone should use Inversify. Could you elaborate?

[AriaFallah]

I don't mean that in a rude way, but just as someone who's stumbled upon the repo it seems like a lot of decorum for simply passing parameters around.

Your README says

InversifyJS is a tool that helps JavaScript developers to write code with a good OO design.

but really doesn't go into depth much after that.

I think it'd really be helpful if you had some examples of how Inversify compares to the alternatives. To me, not saying it's right as it's probably wrong, I feel like everything inversify does, I could do without it, and your README does nothing to convince me otherwise. I feel like it really only caters to people who have used DI before.

So to follow that up. Why, specifically, should I use inversify? What common problems in JS does it solve that I couldn't solve without it?

I will try to document it better in the future (my priority right now is the 2.0 release candidate) but for the moment you can refer to some of my blog posts:

• The current state of dependency inversion in JavaScript
• About object-oriented design and the “class” & “extends” keywords in TypeScript / ES6

IoC containers is somehow controversial and not everyone feels like it is something that they need. If you feel like you need an IoC container then I would like InversifyJS to be the best but if you don't want too use it that is cool too. My personal point of view is that if you code using an OOP style InversifyJS will help. If you are using a FP style then you probably don't need it.

Alright thanks! I'll take a look.

@remojansen both blog posts were exactly what I wanted. Really well written. You should put them at the top of the README or something.

Thanks! I have plans to create page about "motivation" in the wiki. I will add the links there :)

Why this is closed ? I spent days trying to understand why would someone use Inversify. This motivation qutoes is not enough.

JavaScript now supports object oriented (OO) programming with class based inheritance. These features are great but the truth is that they are also dangerous.

We need a good OO design to protect ourselves from these threats. The problem is that OO design is difficult and that is exactly why we created InversifyJS.

InversifyJS is a tool that helps JavaScript developers to write code with a good OO design.

A motivation page is highly recomanded with examples !

I asked chatGPT about this and this is what it had to say.

Inversify provides a number of benefits over traditional manual dependency management in JavaScript:

1. Improved maintainability: Inversify provides a centralized and standardized way to manage dependencies, which can lead to a more organized and maintainable codebase over time.
2. Loose coupling: Inversify promotes loose coupling between components, making it easier to change the implementation of a component or reuse it in different parts of the application.
3. Easier testing: By explicitly defining dependencies, Inversify makes it easier to isolate and test individual components, as you can substitute test doubles for the real dependencies.
4. TypeScript support: Inversify provides built-in support for TypeScript, including support for type-checking and improved code navigation.
5. Dynamic binding: Inversify allows you to change the implementation of a component at runtime, making it easier to switch between different implementations of a dependency.
6. Centralized error handling: Inversify provides centralized error handling, making it easier to track down and debug issues with dependencies.
7. Improved scalability: Inversify makes it easier to manage a large number of dependencies and scale your application as it grows.

Overall, Inversify is a useful tool for JavaScript developers who want to write clean, maintainable, and scalable code. By providing a centralized way to manage dependencies, it helps to improve the organization of the codebase and make it easier to isolate and test individual components.

There are a few reasons why one might not want to use Inversify:

1. Increased complexity: Using Inversify can add a certain level of complexity to your codebase, as each component may require its own @injectable decorator and an associated binding in the IoC container.
2. Steep learning curve: Inversify may have a steep learning curve for developers who are not familiar with dependency injection and IoC containers, as it introduces a number of new concepts and patterns.
3. Overhead: Inversify introduces a certain amount of overhead to your application, as it requires you to define and maintain a separate IoC container.
4. Performance: While the performance impact of using Inversify is usually negligible, it may slow down your application if it is not used correctly, for example by injecting too many dependencies into a single component.
5. Over-engineering: In some cases, Inversify may be over-engineering for small projects, where the benefits of using it are outweighed by the added complexity and overhead.

Overall, whether or not Inversify is a good fit for your project depends on the specific needs of your application and the level of experience of your development team. If you're working on a small, simple project with a small number of dependencies, it may not be worth the added complexity. However, if you're working on a large, complex project with many dependencies, Inversify can help you to write cleaner, more maintainable, and more scalable code.

very good answer, good AI 🥇
