How ReduxX works:

Step 1: Install ReduxX and Set Your Initial Global State

To install ReduxX, input the following npm command:

npm install react-state-management --save

In the directory of your main React component, the most parent component that contains all your other components, add the following reduxX.js file:

import ReduxX from 'react-state-management';


export const {

    setUpReduxX,
    setState,
    getState,

    /* Optional Exports: */
    // resetReduxX,
    // getGlobalUseState,
    // oldeFashionedStateManagement

} = ReduxX({

    initialState: [

        {
            keys: [ 'monkey', 'favoriteFood' ],

            value: 'banana',
        },
        {
            // can put a string for the "keys" for single key values
            keys: 'monkey',

            // the value can be of any type,
            // just like using regular React state
            value: { name: 'Curious George', bff: 'Donkey Kong' },
        },
        {
            keys: [ 'monkey', 'height' ],

            value: '69cm',
        },
        {
            keys: [ 'hippo', 'status', 'mood' ],

            value: 'hungry',
        }
    ]    
});

Notes:

a) you can use any number of keys

b) technically you can put this reduxX.js file anywhere, but it makes the most sense to put it in your root folder based on how you access it (in Step 3)

c) you can alternatively use the Object Form for Initial State

Step 2: Set up ReduxX

In the most parent component itself, the component that contains all your other components, set up the ReduxX global state like the following:

import { useState } from 'react';

// Step 2: a) Import the following setUpReduxX function
//            from the file you created in Step 1.
// Note: this particular path assumes the reduxX.js file
//       is in the same directory as this file
import { setUpReduxX } from './reduxX';


// Your "most parent" component
export default () => {

    setUpReduxX( useState );

    return ...
};

Step 3: Easily Set and Get Values to and from the Global State

Now anywhere you normally do a React setState, you can now setState with ReduxX to access a global state and never have to worry about collisions, so exciting!:

// some other module

import { createElement as e } from 'react';

import { setState, getState } from '/*path to reduxX.js file, the file created in Step 1*/';


const handleClick = () => {

    /*
       ReduxX Effortless State Setting and Getting
    */

    // set the global state for one or more items like this:

    setState(

        {
            keys: [ 'monkey', 'favoriteFood' ],

            value: 'apple',
        },
        {
            keys: [ 'hippo', 'status', 'mood' ],

            value: 'full'
        }
    );

    // get the global state for an item like this:

    const monkeyHeight = getState( 'monkey', 'height' );

    console.log(

        `The reduxX monkey is ${ monkeyHeight } tall!`
    );

    // should log: The reduxX monkey is 69cm tall!
};


export default () => e( 'div', { onClick: handleClick } );

This example also includes a ReduxX getState invocation. You can use this function anywhere and this function gets the requested value from the global state! Extreme #swaggy🎅🏿👳🏽🤠👲🏻!

Wow that's it, so easy!

All you need to do is import your ./reduxX.js file you created in Step 1 and then use setState and getState to manage your global state (like in Step 3).

Bonus Features

Alternate Input Formats for the ReduxX setState and getState Functions

For your convenience, and for better code readability, the ReduxX setState and getState functions offer several ways to set and get values to and from the global state.

import { setState, getState } from '/*path to reduxX.js file, the file created in Step 1*/';

/*
   Different input formats for getState
*/

//  The following four getState invocations are equivalent:
getState( 'user' );
getState( [ 'user' ] );
getState({ keys: 'user' });
getState({ keys: [ 'user' ] });


//  The following three getState invocations are equivalent:
getState( 'user', 'profile' );
getState( [ 'user', 'profile' ] );
getState({ keys: [ 'user', 'profile' ] });


/*
   Different input formats for setState
*/

//  The following four setState invocations are equivalent:
setState( 'user', { id: 69 } );
setState( [ 'user' ], { id: 69 } );
setState({ keys: 'user', value: { id: 69 } });
setState({ keys [ 'user' ], value: { id: 69 } });

//  The following two setState invocations are equivalent:
//  (these invocations involve setting multiple values at once)
setState(

    [ 'user', 'name' ], 'Jar Jar Binks',
    'user', { id: 69 },
    [ 'user', 'game' ], 'React state library author'
);
setState(

    {
        keys: [ 'user', 'name' ],  
        value: 'Jar Jar Binks'
    },
    {
        keys: [ 'user' ],  
        value: { id: 69 }
    },
    {
        keys: [ 'user', 'game' ],  
        value: 'React state library author'
    }
);

Object Form for Initial State

In Step 1, we set up our initial state with an array of objects that each have a keys and a value property. We can alternatively set up our initial state with an object. This can be more suitable for ReduxX apps with a larger number of state keys because it easily allows you to organize your initial state in a modular way (because it easily allows you to put sections of your initial state in different files if you want).

The code below shows you how to use the Object Form for Initial State to set the same initial state as in Step 1:

import ReduxX, {

    /*
        General Use Case:
            use the ReduxX VALUE key to set the initial state value
            for the specified key
    */
    VALUE,

    /*
        Common/Simple Use Case:
            alternatively use the ReduxX special "v" function
            to specify the initial state value
            for simple ReduxX initial state object configurations
    */
    v,

} from 'react-state-management';


export const {

    setUpReduxX,
    setState,
    getState,

    /* Optional Exports: */
    // resetReduxX,
    // getGlobalUseState,
    // oldeFashionedStateManagement

} = ReduxX({

    initialState: {

        monkey: {

            [VALUE]: { name: 'Curious George', bff: 'Donkey Kong' },

            favoriteFood: v( 'banana' ),

            height: {

                [VALUE]: '69cm'
            }
        },

        hippo: {

            status: {

                mood: v( 'hungry' )
            }
        }
    }
});

Reset to Initial State

To reset your app's ReduxX state to the initial state specified in Step 1, simply execute the resetReduxX function as follows:

import { createElement as e } from 'react';

import { resetReduxX } from '/*path to reduxX.js file, the file created in Step 1*/';


export default () => e( 'div', { onClick: resetReduxX } );

Note: the commented out resetReduxX function in Step 1 must be uncommented so that it's exported🦖

You can also specify only certain keys to be reset using the optional listOfKeysToExclude and listOfKeysToInclude input values:

resetReduxX({

    listOfKeysToExclude: [
        [ 'monkey', 'favoriteFood' ],
        [ 'hippo', 'status', 'mood' ]
    ]
});

// or

resetReduxX({

    listOfKeysToInclude: [
        [ 'monkey', 'favoriteFood' ],
        [ 'hippo', 'status', 'mood' ]
    ]
});

Olde Fashioned State Management and Global Use State

You can use the oldeFashionedStateManagement system to manually adjust your ReduxX initialized state.

You can also access and alter the global state manually using getGlobalUseState() to get the most parent component's useState function:

// some other module

import { createElement as e } from 'react';

import { oldeFashionedStateManagement, getGlobalUseState } from '/*path to reduxX.js file, the file created in Step 1*/';

/*
    Note:
        the commented out `oldeFashionedStateManagement` object in Step 1
        must be uncommented so that it's exported🦕
        same with the commented out `getGlobalUseState` function🦖
*/

const handleClick = ({ setCount }) => {

    setCount( '🐒🍌' );

    /*
       Olde Fashioned State Setting and State Getting:
    */
    const {

        stateKeyMapper,
        KEY,
        getStateKeyToStateTools

    } = oldeFashionedStateManagement;

    /*
        NOTE:
            the following assumes the state has been set up
            like how it was in the first section
    */
    const stateKey = stateKeyMapper.monkey.favoriteFood[ KEY ];

    const stateKeyToStateTools = getStateKeyToStateTools();

    const stateTools = stateKeyToStateTools[ stateKey ];

    const { stateValue, stateSetter } = stateTools;

    console.log( stateValue );
    // will log 'banana'

    stateSetter( 'apple' );
    /*
        sets the state value for the [ 'monkey', 'favoriteFood' ]
        state keys to be 'apple'
        
        this is the state setter function
        that's returned by React.useState( ... ) 
        (the one associated with that state value)
    */
};


const div = () => {

    /*
       State Setting and State Getting Using Global Use State:
    */
    const globalUseState = getGlobalUseState();

    const [ count, setCount ] = globalUseState( 1 );

    console.log( count );
    // will log 1

    return e( 'div', { onClick: () => handleClick({ setCount }) } );
};

Multiple ReduxXs

It should be noted that you can have multiple ReduxX instances. This could be useful if you have a larger app. Your file folder structure could look something like this:

/
|
|
/LargeAppComponentA
    reduxX.js // file set up in step 1
    main.js
    ...
|
|
/LargeAppComponentB
    reduxX.js // another file for this large component set up in step 1
    main.js
    ...
|
|
...

Your ReduxX, your way!🦑
