React JS code:
I want the src/app.jsx to do export default App when the REACT_APP_AUTH_SERVER variable in .env does not exist or have other value, and do export default withAuthenticator(App) when the REACT_APP_AUTH_SERVER variable in .env does exist, and has value aws-cognito:
src/app.jsx:
import React, { Component } from 'react';
import SecuredGate from './SecuredGate/SecuredGate';
import { withAuthenticator } from '@aws-amplify/ui-react'
import './App.css';
import '../fontStyles.css';
class App extends Component {
render() {
return (
<div>
<SecuredGate />
</div>
);
}
}
const Result = () => {
if (process.env.REACT_APP_AUTH_SERVER && process.env.REACT_APP_AUTH_SERVER === "aws-cognito"){
return withAuthenticator(App);
}
return App;
}
// export default App;
// export default withAuthenticator(App)
export default Result;
However, this is not working.
If I do:
export default App;
// export default withAuthenticator(App)
, it works, and if I do:
// export default App;
export default withAuthenticator(App)
it works as well.
So what am I missing?
I think the problem is that the Result component returns a component instead of an element. To understand this better look at what App component does when called with <App />. It runs the code in its body and returns some markup. But what happens if you call <Result />. It will run the code in its block and return another component (a function). So to solve this you can try:
const Result = (process.env.REACT_APP_AUTH_SERVER && process.env.REACT_APP_AUTH_SERVER === "aws-cognito")
? withAuthenticator(App)
: App;
}
export default Result;
