React Material UI - Export multiple higher order components

Just try this

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

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

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);

Without recompose or compose:

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