# FAQ

## What are the benefits of NgRx Ducks?

* ⚙️ Create both Reducer and Action Automatically
* 🤫 Get rid of verbose action declarations
* ️️️⤵️ Reduce imports of Action Types and Action Creators
* 💉 Use typed Services instead of dispatching Actions
* 🙅‍ No code generation that needs to be maintained manually

## What is a Duck?

A Duck bundles the tasks of

* [Action Creator](https://redux.js.org/glossary#dispatching-function)
* [Dispatching Function](https://redux.js.org/glossary#action-creator)
* [Case Reducer](https://redux.js.org/recipes/structuring-reducers/refactoring-reducer-example)

As user, you only need to declare which method needs to be executed when a certain action is dispatched. Multiple Ducks are used to generate the [Reducer](https://redux.js.org/glossary#reducer) automatically. You end up writing a class containing pure functions. Leave the rest to `@ngrx-ducks/core`. Components are fully independent of Redux-Architecture

## Which version of **ngrx** is supported?

The version number of **@ngrx-ducks** is aligned with **ngrx/platform**. The major versions of both projects are compatible with each other.

## What happens to the previous Decorator-API?

*Short answer: Nothing*

👍 The Decorator API is still there and can be used. If you already use NgRx Ducks you do not have to worry about breaking changes in your app.

## **Why does the Decorator-API needs a successor?**

*Short answers:*

* *Better compatibility with NgRx’s types*
* *Reduction of boilerplate*
* *Make component fully independent of Redux-Architecture*
* *Even better type-support*

There are various reasons that motivated to improve the API of NgRx Ducks. A video discusses the differences in more detail. You are welcome to join the discussion.

## What about Angular 8? <a href="#id-29e0" id="id-29e0"></a>

The new API isn’t only ready for Angular 9. 🎉 Since NgRx-Ducks 8.4 you can already benefit from `createDuck` and its friends.

{% hint style="warning" %}
Please note that NgRx Ducks 8 is hosted under the co-IT scope. You need to run `npm install @co-it/ngrx-ducks@8.4` to get the Angular 8 compatible version.
