I am getting this eslint error:
Prefer default export
import React, { Component } from 'react';
class HomePage extends Component {
render() {
return (
<div className="Section">HomePage</div>
);
}
}
export { HomePage };
I have tried doing:
export { default as Homepage };
and then I get a fatal parsing error.
Then I changed it to:
export default HomePage;
Which clears the eslint error.
But then throws:
'./HomePage' does not contain an export named 'HomePage'.
Because I am calling HomePage like this:
import { HomePage } from './HomePage';
If I remove the brackets then I get this error:
"export 'default' (imported as 'HomePage') was not found in './HomePage'
import HomePage from './HomePage';
<PrivateRoute exact path="/" component={HomePage} />
What would be the proper way of changing this to the preferred default export?

From eslint-plugin-import
When there is only a single export from a module, prefer using default export over named export.
class HomePage extends Component {
//....
}
export default HomePage
In another file :
import HomePage from './Hello';
Check here codesandbox
Here's an example using functions:
function HomePage() {
function aHelperMethod() {
//
}
return {
aHelperMethod,
}
}
Now to import it in another file
import HomePage from './Hello';
And to use it you'll have to instantiate it
const homePage = HomePage()
homePage.aHelperFunction()
In some cases there should be more than one named export in the module.
export const foo = 'foo';
export const bar = 'bar';
