React Material UI - Export multiple higher order components

Question

I\'m stuck on exporting material-ui styles with redux connector. Here is my code:

import React, { Component } from \'react\';
import { connect } from \'react         


        

Answer 1

Just try this

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

Where App is your component. It works fine for me.

Answer 2

Take a look at how it's being handled in the material-ui docs site, specifically in the AppFrame component:

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

They're using recompose to do this.

So in your case, it would be:

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);

Complete Component

    import React from "react";
    import { makeStyles } from "@material-ui/core/styles";
    import ExpansionPanel from "@material-ui/core/ExpansionPanel";
    import ExpansionPanelSummary from "@material-ui/core/ExpansionPanelSummary";
    import ExpansionPanelDetails from "@material-ui/core/ExpansionPanelDetails";
    import Typography from "@material-ui/core/Typography";
    import ExpandMoreIcon from "@material-ui/icons/ExpandMore";
    import { withStyles } from "@material-ui/core/styles";
    import { connect } from "react-redux";
    import { fetchPosts } from "../../store/actions/postActions";
    import PropTypes from "prop-types";

    const useStyles = theme => ({
        root: {
            marginLeft: 250,
            marginRight: 10
        },
        heading: {
            fontSize: "1rem",
            fontWeight: theme.typography.fontWeightRegular
        }
    });

    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
                        expandIcon={<ExpandMoreIcon />}
                        aria-controls="panel1a-content"
                        id="panel1a-header">
                        <Typography className={classes.heading}>{post.title}</Typography>
                    </ExpansionPanelSummary>
                    <ExpansionPanelDetails>
                        <Typography>{post.body}</Typography>
                    </ExpansionPanelDetails>
                </ExpansionPanel>
            ));
            return <div className={classes.root}>{postItem}</div>;
        }
    }

    SimpleExpansionPanel.propTypes = {
        fetchPosts: PropTypes.func.isRequired,
        postsa: PropTypes.array.isRequired,
        newPost: PropTypes.object
    };

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

    export default connect(
        mapStateToProps,
        { fetchPosts }
    )(withStyles(useStyles)(SimpleExpansionPanel));

Answer 4

Without recompose or compose:

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

Answer 5

You may use this below. As both withStyles and connect were higher order components

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

Answer 6

install npm install recompose or yarn add recompose

and on your export section

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

and I forgot to export my store.
