react-redux-mvc

Implementation of MVC pattrern based on React-Redux bunch keeping one direction data flow (flux pattern)

index.js (entry point of application)

/*
* in place of this helper can be superagent.js for example, or other asynс function. It is used by middleware to
* support async actions functionality
* */

    }, 3000);
  });
}


const appStore = function () {

}();

ReactDOM.render(
  <Provider store={appStore}>
    <ReactReduxMvc store={appStore}>

Installation

npm i react-redux-mvc -S

Example

Для того, чтобы посмотреть рабочий пример, нужно собрать его командой npm run example из корневой директории проекта, затем открыть файл ./example/index.html Пример работает локально, без веб-сервера
