Thinking in Redux: Migrating from MVC to React‑Native State Management

The author, a former front‑end engineer at Hujiang, shares a practical guide for developers who are moving from a classic MVC (or MVVC) mindset to using Redux in a React‑Native mobile application. The article does not cover how React‑Native works internally; instead, it focuses on the conceptual shift required to think in Redux.

To help readers make the transition, the author draws direct analogies between MVC concepts and Redux components: Actions correspond to controllers , Reducers act like models , the Store is a unique container that holds the entire application state, and Components serve as the views . This mapping clarifies how data flows in a unidirectional manner in Redux, contrasting with the bidirectional flow typical of MVC.

The article also highlights the key difference that Redux enforces a single‑direction data flow: actions are dispatched, reducers produce a new immutable state, and the updated state is then passed down to components as props.

Implementation steps are outlined as follows:

Define your actions.

Create reducers to handle those actions.

Connect actions to components via props.

Render the components in the view.

Below are the essential code snippets, kept intact and wrapped in

export const SAVE_NAME = "SAVE_NAME";

export function modifyName(name) {
    return {
        type: MODIFY_NAME,
        payload: { name }
    };
}

export function saveName() {
    return { type: SAVE_NAME };
}

import * as constants from '../actions.js';

const initialState = {
    name: '',
    isSaved: false
};

function reducer(state = initialState, action) {
    switch (action.type) {
        case constants.MODIFY_NAME:
            return { ...state, name: action.payload.name };
        case constants.SAVE_NAME:
            return { ...state, isSaved: !state.isSaved };
        default:
            return state;
    }
}
export default reducer;

'use strict';
import React, { Component } from 'react';
import { connect } from 'react-redux';
import Name from './presentational/Name';
import * as actions from './actions/name';

class NameContainer extends Component {
    render() {
        return (
            <Name
                name={this.props.name}
                isSaved={this.props.isSaved}
                modifyName={this.props.modifyName}
                saveName={this.props.saveName}
            />
        );
    }
}

const mapStateToProps = (state) => {
    const { name, isSaved } = state.name;
    return { name, isSaved };
};

const mapDispatchToProps = (dispatch) => ({
    modifyName: (name) => dispatch(actions.modifyName(name)),
    saveName: () => dispatch(actions.saveName())
});

export default connect(mapStateToProps, mapDispatchToProps)(NameContainer);

'use strict';
import React, { Component } from 'react';
import { Text, TextInput, TouchableOpacity, View } from 'react-native';

class Name extends Component {
    render() {
        return (
            <View>
                <TextInput
                    multiline={false}
                    value={this.props.name}
                    placeholder="Full Name"
                    onChangeText={(name) => this.props.modifyName(name)}
                />
                <TouchableOpacity onPress={() => this.props.saveName()}>
                    <Text>Save</Text>
                </TouchableOpacity>
            </View>
        );
    }
}
export default Name;

By following these patterns, developers can replace the familiar MVC workflow with a Redux‑centric approach, achieving a clear, predictable state management system for React‑Native applications.

The author also provides links to the team’s demo app and notes common pitfalls, such as understanding where data travels and how actions are wired to reducers.
