Exporting two functions in JavaScript

Currently utilizing React, Redux, and experimenting with Material-UI integration. The example codes provided by Redux and Material-UI libraries include an 'export' statement at the end.

Redux:

export default connect(mapStateToProps, actions)(myComponent)

Material-UI:

export default withStyles(styles)(myComponent);

Attempting to combine both exports together, I encountered the need to remove the 'default'. Here's what I thought it should be:

This method does not work:

export {
  connect(mapStateToProps, actions)(myComponent),
  withStyles(styles)(myComponent)
}

Error:

"Syntax error: Unexpected token, expected , (120:15)
       export {connect(mapStateToProps, actions)(myComponent)}
                      ^

Trying this approach didn't yield the desired results: I attempted to assign a name to the function, but for unknown reasons, the function was not called as expected.

import * as myConnect from 'react-redux'
...
export const connect = myConnect.connect(mapStateToProps, actions)(View)

Unsure of the underlying issue causing this problem, I find myself in a standstill. Any assistance would be greatly appreciated :-)

EDIT Although I have yet to find a solution, I managed to work around the issue. I decided to separate the component (myComponent) into its own file. This approach has improved the overall design, now allowing for a clear distinction between pure components and containers.

Answer №1

When it comes to building Higher Order Components (HOC), there is a solution that many people find useful. One option is to utilize the Recompose utility, which involves adding another package to your project. Check out this informative article on the topic.

If I were to write code for you, here is an example of how I would use Recompose to build a HOC:

import compose from 'recompose/compose';

//...your component code goes here

export default compose(withStyles(styles), connect(mapStateToProps, actions))(myComponent);

Answer №2

{
  combine(connect(mapStateToProps, actions)(myComponent), withStyles(styles)(myComponent)),
}

Oops! Looks like the keys are missing in this object.

{
    connected: connect(mapStateToProps, actions)(myComponent),
    styled: withStyles(styles)(myComponent)  
}

Answer №3

Transform them into named exports:

export const myConnection = connect(mapStateToProps, actions)(myComponent);

export const customStyles = withStyles(styles)(myComponent);

Afterwards, utilize named imports:

import {myConnection} from './yourscript';
