import ReduxPlugin from '@blueeast/bluerain-plugin-redux';

BR.boot({
    plugins: [ReduxPlugin]
})

Filters

This plugin provides complete flexibility to modify the main redux store. This is done by providing various filter hooks at different stages of store initialization. All filter hooks of this plugin are executed during the execution of bluerain.system.app filter hook.

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:

Name	Type	Description
SystemApp	React.Component	The main system app component.

Returns:

Name	Type	Description
SystemApp	React.Component	The main system app component.

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:

Name	Type	Description
initialState	Object	initialState Object

Returns:

Name	Type	Description
initialState	Object	initialState Object

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:

Name	Type	Description
reducers	Object	The reducer object. This object will be sent as a param to the combineReducers of Redux after callback execution.

Returns:

Name	Type	Description
reducers	Object	The reducer object. This object will be sent as a param to the combineReducers of Redux after callback execution.

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:

Name	Type	Description
reducers	Object	The reducer object. This object will be sent as a param to the combineReducers of Redux after callback execution.

Returns:

Name	Type	Description
reducers	Object	The reducer object. This object will be sent as a param to the combineReducers of Redux after callback execution.

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:

Name	Type	Description
middlewares	Array	This is an array of redux middlewares. This array will be sent as a param to the applyMiddleware of Redux after callback execution.

Returns:

Name	Type	Description
middlewares	Array	This is an array of redux middlewares. This array will be sent as a param to the applyMiddleware of Redux after callback execution.

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:

Name	Type	Description
enhancers	Array	This is an array of redux enhancers. This array will be sent as a param to the compose of Redux after callback execution.

Returns:

Name	Type	Description
enhancers	Array	This is an array of redux enhancers. This array will be sent as a param to the compose of Redux after callback execution.

bluerain.redux.composed

composed	Array	This is the composed enhancers array (by passing enhancers array as a parameter to the compose function), right before they are used in the redux store.
enhancers	Array	This is an array of redux middlewares. This array was passed as a parameter to the compose function. The result was as the first param of this function.

Returns:

Name	Type	Description
composed	Array	This is the composed enhancers array (by passing enhancers array as a parameter to the compose function), right before they are used in the redux store.
