Polymer bindings for Redux.

Polymer Redux

Polymer bindings for Redux. Bind store state to properties and dispatch actions from within Polymer Elements.

Polymer is a modern library for creating Web Components within an application. Redux is a state container for managing predictable data. Binding the two libraries together allows developers to create powerful and complex applications faster and simpler. This approach allows the components you build with Polymer to be more focused on functionality than the applications state.

Polymer 3

Polymer 3 is currently under beta release, checkout: https://github.com/tur-nr/polymer-redux/tree/dev/v2.x

Installation

bower install --save polymer-redux

Example

// Create a Redux store
const store = Redux.createStore((state = {}, action) => state)

// Create the PolymerRedux mixin
const ReduxMixin = PolymerRedux(store)

// Bind Elements using the mixin
class MyElement extends ReduxMixin(Polymer.Element) {
    static get is() {
        return 'my-element'
    }

    connectedCallback() {
        super.connectedCallback();
        const state = this.getState();
    }
}

// Define your Element
customElements.define(MyElement.is, MyElement)

Now MyElement has a connection to the Redux store and can bind properties to it's state and dispatch actions.
