Fluxxor Components

Higher-order components for use with Fluxxor. These are intended to replace FluxMixin and StoreWatchMixin when using ECMAScript 2015 classes.

API

createContext(flux: Flux): Component

Returns a new component whose elements pass the given Flux instance down as a context. Every child element of this new component will have the Flux available as the context prop named flux.

Intended to replace FluxMixin.

Example

/* Create the flux instance. */
const flux = new Fluxxor.Flux(...);
/* Create the new component with a flux instance as context. */
const FluxContext = createFluxContext(flux);
 
class App extends React.Component {
  /* Declare that we accept the Flux instance from the context. */
  static get contextTypes() {
    return {
      flux: React.PropTypes.object
    };
  }
 
  render() {
    /* Use the flux instance. */
    const {flux} = this.context;
    const actionNames = Object.keys(flux.actions);
    return <ul>{actionNames.map(name =>
      <li key={name}>{name}</li>
    )}</ul>;
  }
}
 
/* Render the instance: */
React.render(
  document.getElementById('react'),
  <FluxContext>
    <App />
  </FluxContext>
);

watchStores(Component, ...StoreNames: String, onChange: (Flux) => Object): Component

Watches the given stores, and passes the updates state as props to the given component. Use the returned component as if it was the given component; except it watches Fluxxor stores.

That is, it returns a component that wraps the given React component and calls onChange when any of the given stores are changed. The return of onChange is used to update the state; all of this state is subsequently passed to the wrapped component as props, along with its original props. Assumes flux exists in the context (i.e., in the manner that createFluxContext() would provide it) or the Flux instance passed as a prop named flux.

Intended to replace StoreWatchMixin.

/* We're bringin' it back! */
class Blink extends React.Component {
  render() {
    const {children, speed} = this.props;
    const styles = {
      animation: `blink ${speed} steps(2, start) infinite`
    };
    return <div style={styles}>{children}</div>;
  }
}
 
/* Get the data from the Twitter store. */
const BlinkFromTwitter = watchStores(Blink, 'twitter', (flux) => ({
  children: flux.store('twitter').getLatestTweet()
}));
 
/* Render the instance: */
React.render(
  document.getElementById('react'),
  <FluxContext>
    <BlinkFromTwitter speed="250ms" />
  </FluxContext>
);
