Im trying to use user roles to determine whether or not to display a component. So im trying to use an HOC to handle that functionality, but im getting an error i dont quite understand. here is the code:
import React from 'react';
import { getUserRoles } from 'modules/api/account/user/selectors';
import { connect } from 'react-redux';
const RestrictedOrFallBack = ({
wrappedComponent,
role,
userRoles,
fallback,
}) => {
if (userRoles.includes(role)) return wrappedComponent;
return fallback;
};
const mapStateToProps = state => ({
userRoles: getUserRoles(state),
});
const ConnectedRestrictedOrFallback = connect(mapStateToProps)(RestrictedOrFallBack);
export { RestrictedOrFallBack };
export default ({
role,
fallback = () => (<div />),
}) => WrappedComponent => (
<ConnectedRestrictedOrFallback
role={role}
fallback={fallback}
WrappedComponent={WrappedComponent}
/>
);
The error im getting is: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: <Connect(RestrictedOrFallBack) />
What am I doing wrong?
EDIT: updated code according to answer
import React from 'react';
import { getUserRoles } from 'modules/api/account/user/selectors';
import { connect } from 'react-redux';
import compose from 'utility/compose';
const RestrictedOrFallBack = ({
wrappedComponent,
role,
userRoles,
fallback,
}) => {
debugger;
if (userRoles && userRoles.includes(role)) return wrappedComponent;
return fallback;
};
const mapStateToProps = state => ({
userRoles: getUserRoles(state),
});
const ConnectedRestrictedOrFallback = compose(
connect(mapStateToProps),
RestrictedOrFallBack,
);
export { RestrictedOrFallBack };
export default ({
role,
fallback = () => (<div />),
}) => wrappedComponent => ConnectedRestrictedOrFallback({
role,
fallback,
wrappedComponent,
});
You cannot "connect" an HOC. "connect" returns an HOC itself and HOC's can only be applied to actual components.
What you are trying to do is compose 2 HOCs to form a new HOC.
so you would do something like:
import { connect, compose } from 'redux';
const ConnectedRestrictedOrFallback = compose(
connect(mapStateToProps),
RestrictedOrFallback
);
