I would like to have a smart ponent/container that handles CRUD operations for Product entity and I have the following code:

function productContainerRender(WrappedComponent) {
    return class extends React.Component {
        constructor(props) {
            super(props);
            this.fetchProducts = this.fetchProducts.bind(this);
        }

        fetchProducts = (page) => {
            this.props.dispatch(fetchProductsBegin());
            productsApi.getAll(page)
                .then(response => {
                    if (response.data) {
                        this.props.dispatch(fetchProductsSuccess(response.data._embeddedpanies));
                    } else {
                        this.props.dispatch(fetchProductsFailure({message: "Fetching products failed"}));
                    }
                });
        };

        ponentDidMount() {
            // this.fetchProducts(1);
        }

        render() {
            // ... and renders the wrapped ponent with the fresh data!
            // Notice that we pass through any additional props
            return <WrappedComponent {...this.props} fetchProducts={this.fetchProducts} />;
        }
    }
}

const productSelector = createSelector(
    state => state.products,
    items => items,
    loading => loading,
    error => error,
);

const mapStateToProps = createSelector(
    productSelector,
    (products) => ({
        products,
    })
);

const ListProducts = productContainerRender(
    ListProductComponent
);

const AddProduct = productContainerRender(
    AddProductComponent
);

export default connect(mapStateToProps)(ListProducts,AddProduct);

When I try to call from App ponent, it always shows up

Any idea how to make it so I can export both ListProducts,AddProduct and call from anywhere on the app.

You can’t return multiple ponent at the same time with one call connect, remember that you are export default and you should return only one single function/ponent, remember that connect only return one single ponent at time, so the way you can do it is like

export default {
  ListProduct: connect(mapStateToProps)(ListProducts),
  AddProduct: connect(mapStateToProps)(AddProduct)
}

So when importing the ponents you can do

import Components from ‘.../your/path’;
class MyView extends React.Component{
  render(){
    return <Components.ListProducts/>
  }
}

You can only pass one Component to connect. So, instead, you’d have to do two connects:

const ConnectedListProducts = connect(mapStateToProps)(ListProducts)
const ConnectedAddProduct = connect(mapStateToProps)(AddProduct)

Since you can have only one default export, you‘d have to use named export in this case or split up those two ponents in two files.
