React Material User Interface - Export multiple higher order components

Question

I am stuck in exporting material-ui styles with redux connector. Here is my code:

import React, { Component } from 'react';
import { connect } from 'react-redux';
import Drawer from 'material-ui/Drawer';
import { withStyles } from 'material-ui/styles';
import PropTypes from 'prop-types';

const mapStateToProps = state => ({});

const reduxConnector = connect(mapStateToProps, null);
const styles = theme => {
    console.log(theme);
    return ({
        paper: {
            top: '80px',
            boxShadow: theme.shadows[9]
        },
    });
};

class Cart extends Component {

    render() {
        const { classes } = this.props;
        return (
            <Drawer
                open
                docked
                anchor="right"
                classes={{ paper: classes.paper }}
            >
                <p style={{ width: 250 }}>cart</p>

            </Drawer>
        );
    }
}

export default withStyles(styles, {name: 'Cart'})(Cart);
export default reduxConnector(Cart); // I want to add this

I tried:

export default reduxConnector(withStyles(styles))(Cart); // return Uncaught TypeError: Cannot call a class as a function

export default withStyles(styles, {name: 'Cart'})(reduxConnector(Cart)); // return Uncaught Error: Could not find "store" in either the context or props of "Connect(Cart)". Either wrap the root component in a <Provider>, or explicitly pass "store" as a prop to "Connect(Cart)".

Any solution?

Answer 1

install npm install recomposeoryarn add recompose

and in the export section

export default compose(
    withStyles(styles, {
        name: 'App',
    }),
    connect(),
)(AppFrame);

and I forgot to export my store.

Answer 2

Just try this

export default connect(mapStateToProps, mapDispatchToProps)(withStyles(styles)(App));

Where the application is your component. It works great for me.

Answer 3

, material-ui docs, AppFrame:

export default compose(
  withStyles(styles, {
    name: 'AppFrame',
  }),
  withWidth(),
  connect(),
)(AppFrame);

recompose .

, :

import React, { Component } from 'react';
import compose from 'recompose/compose';
import { connect } from 'react-redux';
import Drawer from 'material-ui/Drawer';
import { withStyles } from 'material-ui/styles';
import PropTypes from 'prop-types';

const styles = theme => {
  console.log(theme);
  return {
    paper: {
      top: '80px',
      boxShadow: theme.shadows[9],
    },
  };
};

const Cart = ({ classes }) =>
  <Drawer open docked anchor="right" classes={{ paper: classes.paper }}>
    <p style={{ width: 250 }}>cart</p>
  </Drawer>;

const mapStateToProps = state => ({});

export default compose(
  withStyles(styles, { name: 'Cart' }),
  connect(mapStateToProps, null)
)(Cart);

Answer 4

recompose compose:

Cart = withStyles(styles, {name: 'Cart'})(Cart);
export default reduxConnector(Cart);

Answer 5

. Styles,

export default withStyles(styles, {name: 'Cart'})(connect(mapStateToProps, mapDispatchToProps), Cart);

    const useStyles = theme => ({

            fontSize: "1rem",

    class SimpleExpansionPanel extends React.Component {
        UNSAFE_componentWillMount() {
            this.props.fetchPosts();
        }

        UNSAFE_componentWillReceiveProps(nextProps) {
            if (nextProps.newPost) {
                this.props.postsa.unshift(nextProps.newPost);
            }
        }

        render() {
            const { classes } = this.props;
            const postItem = this.props.postsa.map(post => (
                <ExpansionPanel key={post.id}>
                    <ExpansionPanelSummary

    const mapStateToProps = state => ({
        postsa: state.postss.items,
        newPost: state.postss.item
    });

    export default connect(
        mapStateToProps,

    )(withStyles(useStyles)(SimpleExpansionPanel));

Answer 7

export default connect(mapStateToProps)((withStyles(styles)(ComponentNameToExport)));

Answer 8

:

 export default withStyles(styles, { withTheme: true }(connect(mapStateToProps,mapDispatchToProps)(App));
