bluerain.redux.beforeInit

This hook is executed before anyother hooks are registered or executed.

bluerain.redux.app

This hook gives the ability to modify the main System App component that gets wrapped in Redux's Provider.

Parameters:

Returns:

Example:

This example wraps the System App with a Redux provider by using a withRedux higher order component (HOC).

import BR from '@blueeast/bluerain-os';
import withRedux from './withReduxBasedComponent';

BR.Filters(
    'bluerain.redux.app', 
    function AddReduxPluginToSystemApp(App) {
        return withReduxBasedComponent(App);
    }
);

bluerain.redux.initialState

This hook gives the ability to modify the initial state sent to the redux store.

Parameters:

Returns:

Example:

This example sets the bluerain.taskbar.active state of the redux store to true at system boot time.

import BR from '@blueeast/bluerain-os';

BR.Filters.add(
    'bluerain.redux.initialState',
    function ActivateTaskbar(state) {
        return Object.assign({}, state, {
            bluerain: {
                taskbar: {
                    active: true
                }
            }
        })
    }
);

bluerain.redux.reducers

This hook gives the ability to modify the redux store's reducer.

Parameters:

Returns:

Example:

This example adds a reducer to bluerain state, which will be accessible at foo.

import BR from '@blueeast/bluerain-os';
import reducer from './reducer';

BR.Filters.add(
    'bluerain.redux.reducers', 
    function AddReducer(reducers) {
        return Object.assign({}, reducers, {
            foo: 'bar'
        });
    }
);

bluerain.redux.reducers.bluerain

This hook gives the ability to modify the nested bluerain reducer.

Parameters:

Returns:

Example:

This example adds a taskbar reducer to bluerain state, which will be accessible at bluerain.taskbar.

import BR from '@blueeast/bluerain-os';
import reducer from './reducer';

BR.Filters(
    'bluerain.redux.reducers.bluerain',
    function AddReducers(reducers) {
        return Object.assign({}, reducers, {
            taskbar: reducer
        })
    }
);

bluerain.redux.middlewares

This hook gives the ability to add or modify custom middlewares to the main redux store.

Parameters:

Returns:

Example:

This example adds a taskbar reducer to bluerain state, which will be accessible at bluerain.taskbar.

import BR from '@blueeast/bluerain-os';
import customMiddleware from './customMiddleware';

BR.Filters(
    'bluerain.redux.middlewares', 
    function AddMiddleware(middlewares) {
        return middlewares.push(customMiddleware());
    }
);

bluerain.redux.enhancers

This hook gives the ability to modify the redux enhancers array. After execution, this array will be sent to the redux's compose function.

Parameters:

Returns:

bluerain.redux.composed

This hook gives the ability to modify the final composed enhancers array (by passing enhancers array as a parameter to the compose function), right before they are used in the redux store. Parameters:

Returns:

bluerain.redux.provider

This hook gives the ability to modify the Provider component of the redux store.

Parameters:

Returns:

Example:

This example replaces the original provider with Apollo's provider.

import BR from '@blueeast/bluerain-os';
import { ApolloProvider } from 'react-apollo';

BR.Filters(
    'bluerain.redux.provider', 
    function ChangeProvider(Provider) {
        return ({ store, children }) => (<ApolloProvider store={store} client={client}>{children}</ApolloProvider>);
});
