What is Redux?

Redux is a popular approach to managing state in applications. It emphasises:

  • A single, immutable data store.
  • One-way data flow.
  • An approach to change based on pure functions and a stream of actions.

You can find lots of excellent documentation here: Redux.

What is @angular-redux?

We provide a set of npm packages that help you integrate your redux store into your Angular 2+ applications. Our approach helps you by bridging the gap with some of Angular's advanced features, including:

  • Change processing with RxJS observables.
  • Compile time optimizations with NgModule and Ahead-of-Time compilation.
  • Integration with the Angular change detector.

Getting Started

Examples

Here are some examples of the angular-redux family of packages in action:

In-Depth Usage

@angular-redux/store uses an approach to redux based on RxJS Observables to select and transform data on its way out of the store and into your UI or side-effect handlers. Observables are an efficient analogue to reselect for the RxJS-heavy Angular world.

We also have a number of 'cookbooks' for specific Angular topics:

Hacking on angular-redux/store

Want to hack on angular-redux/store or any of the related packages? Feel free to do so, but please test your changes before making any PRs.

Here's how to do that:

  1. Write unit tests. You can check that they work by running npm test.
  2. Run the linter. If your editor doesn't do it automatically, do it manually with npm run lint.
  3. Test your changes in a 'real world scenario'. We use the example-app for this, using some npm fakery to 'publish the package locally':

  4. clone the example app (git clone https://github.com/angular-redux/example-app.git)

  5. generate a 'local package' (cd to your angular-redux/store clone and run npm pack). This will create a .tgz file.
  6. hook your 'local package' up to your example-app (cd to your example-app clone and run npm install --save /path/to/the/tgz/file/from/above)
  7. run ng serve --aot

Please make sure your changes pass Angular's AoT compiler, because it's a bit finicky with TS syntax.

Index

Type aliases

Comparator

Comparator: function

Type declaration

    • (x: any, y: any): boolean
    • Parameters

      • x: any
      • y: any

      Returns boolean

FunctionSelector

FunctionSelector: function

Type declaration

    • (s: RootState): S
    • Parameters

      • s: RootState

      Returns S

PathSelector

PathSelector: (string | number)[]

PropertySelector

PropertySelector: string | number | symbol

Selector

Selector: PropertySelector | PathSelector | FunctionSelector<RootState, S>

Transformer

Transformer: function

Type declaration

    • (store$: Observable<RootState>): Observable<V>
    • Parameters

      • store$: Observable<RootState>

      Returns Observable<V>

Functions

WithSubStore

  • WithSubStore(__namedParameters: object): ClassDecorator

dispatch

  • dispatch(): PropertyDecorator
  • Auto-dispatches the return value of the decorated function.

    Decorate a function creator method with @dispatch and its return value will automatically be passed to ngRedux.dispatch() for you.

    Returns PropertyDecorator

enableFractalReducers

  • enableFractalReducers(rootReducer: Reducer<any>): function
  • Parameters

    • rootReducer: Reducer<any>

      Call this on your root reducer to enable SubStore functionality for pre-configured stores (e.g. when using NgRedux.provideStore()). NgRedux.configureStore does it for you under the hood.

    Returns function

      • <A>(state: S, action: A): S
      • Type parameters

        • A: Action

        Parameters

        • state: S
        • action: A

        Returns S

select

  • Selects an observable from the store, and attaches it to the decorated property.

    Type parameters

    • T

    Parameters

    • Optional selector: Selector<any, T>

      A selector function, property name string, or property name path (array of strings/array indices) that locates the store data to be selected

    • Optional comparator: Comparator

      Function used to determine if this selector has changed.

    Returns PropertyDecorator

select$

  • Selects an observable using the given path selector, and runs it through the given transformer function. A transformer function takes the store observable as an input and returns a derived observable from it. That derived observable is run through distinctUntilChanges with the given optional comparator and attached to the store property.

    Think of a Transformer as a FunctionSelector that operates on observables instead of values.

    Type parameters

    • T

    Parameters

    Returns PropertyDecorator
