How to use Redux with React

This project is to understand how redux can be used with react. Everything is in a single script for better understandability. When developing a complex redux-react app, you'll need to modularize (eg. components, actions, reducers etc.)

File: src/index.js

Configuaration

• Clone the project

git clone https://github.com/prabushitha/single-script-react-with-redux.git

• Install dependenies

npm install

• Run the project

npm start

Steps

There are basically 6 steps you need to follow.

Redux Part

1. Create middleware [Optional : But most of the times you'll need a middleware to make your work easier]

const middleware = applyMiddleware(createLogger());

2. Create reducer OR reducers (using combineReducers).

We'll create a single reducer

const initialState = {
    toggled:false
};
const reducer =  (state=initialState, action)=>{
    switch (action.type){
        case 'TOGGLE':
            return {toggled:!state.toggled};
        default:
            return state;
    }
};

3. Create the STORE

const store = createStore(reducer,middleware);

React Part

4. Create react component element

class TodoElement extends React.Component{
    _toggle(){
        this.props.dispatch({type:"TOGGLE",payload:'content'});
    }
    render(){
        return (<button onClick={this._toggle.bind(this)} >{this.props.toggled?'Hide':'Show'}</button>);
    }
}

5. Connect react and redux

const Todo = connect((state)=>{
    return {
        toggled:state.toggled
    };
})(TodoElement);

6. Render react element

ReactDOM.render(<Provider store={store}><Todo /></Provider>, document.getElementById('root'));
registerServiceWorker();
