React State Management without Redux

React RetiX

Demo here

This package is used for state management, it is not intended to become an alternative to Redux. It just provides a different approach to state management in React.

If you're looking for a simple, flexible, effective way to manage the global state of your React application, this package is for you. If you're new to Redux, you're confused with a lot of its concepts such as the store, reducer, action, middleware - Alright, go ahead with React RetiX.

Let's take a look at the detail below:

Competitive benefits:

• Can use any where in your react application, not only in component
• Light-weight
• Easy to use
• Simple of architecture

Install

npm i react-retix

Built-in

MasterStore

• For registering a store, the same concept as createStore in Redux

useSubscriber

• For watching state, the same concept as useSelector in React Hooks + Redux

useEmitter

• For doing action, updating state, the same concept as useDispatch in React Hooks + Redux

Usage

Register

import React, { useState } from 'react';
import { MasterStore } from 'react-retix';

new MasterStore({ state });

const App = () => {

  return <></>
};

const rootElement = document.getElementById('root')
ReactDOM.render(<App />, rootElement)

Watch state

Root (Master store)

import React from 'react';
import { useSubscriber } from 'react-retix';

const App = () => {
  const masterStore = useSubscriber();

  return <></>
};

Children

import React from 'react';
import { useSubscriber } from 'react-retix';

const LoadingIndicator = () => {
  const isLoading = useSubscriber('page.isLoading');

  return isLoading && <Spinner />
};

Update state

Inside component

import React from 'react';
import { useSubscriber } from 'react-retix';

const PostReaction = (post) => {

  const { isAuthenticated } = useSubscriber('user');

  const doLike = () => {
    useEmitter({ isLiked: true });
  }

  return (
    <div>
      { 
        isAuthenticated ? <button onClick={doLike}>Like</button> : <button>Sign in</button>
      }
    </div>
  )
}

Outside component (Either Service, utils or othes)

import { useEmitter } from 'react-retix';

class PostService {
  constructor () {
    //
  }

  getPost () {
    this.api.get('posts').then((data) => {
      useEmitter({ post: data });
    }).catch((err) => {
      useEmitter({ errors: err });
    }).finally(() => {
      useEmitter({ isLoading: false });
    });
  }
}

Others

The usage of tring

To update a state, you can specify the path of an object

useEmitter(val, 'level1.level2.level3.level4');

instead of

useEmitter({ 
  level1: {
    level2: {
      level3: {
        level4: val
      }
    }
  }
});

Both of them works the same, choose a comfortable one base on your use-case.

Deep merge objects

Highly noted that, due to data integrity purpose we decided to use deep merge for updating objects, for example:

Current state

{
  level1: {
    level21: true,
    level22: 'xyz',
    level23: {
      level3: null
    }
  }
}

Update the state with new data

useEmitter({ 
  level1: {
    level21: false
  }
});

The result would be

{
  level1: {
    level21: false, // updated with new value
    level22: 'xyz', // not be removed
    level23: { // not be removed
      level3: null
    }
  }
}

It means all attributes of an object will be persisted as initial values, unless you try to force to remove them all by setting it value to empty object {} or null

Force to remove all attributes

useEmitter({ 
  level1: {} // or null also works
});

The result would be

{ 
  level1: {}
};

Services

React RetiX recommend you to use service to handle business logic of your application.

If you have familiared with Redux, you can imagine that services is the same as what reducers do in Redux architecture.
