Quick Intro To ReactFire v4 Sample Application

• Blog Post & Video - https://dev.to/aaronksaunders/intro-to-reactfire-v4-login-logout-create-account-and-protected-routes-37e5
• ReactFire Repo - https://github.com/FirebaseExtended/reactfire
• updated previously released reactfire intro application to work with v4
• current has auth and create account, will add some CRUD functionality soon
• used Ionic Framework for UI but the code is react so it should work in all cases

Two Approaches For Checking For Auth User

From the react router documentation..

for this to work with IonicReactRouter, I had to remove the location from being passed in to the redirect as state. IonicRouter doesnt support Switch, so the thing just kept looping

// A wrapper for <Route> that redirects to the login
// screen if you're not yet authenticated.
export const PrivateRoute = ({
  children,
  location,
  ...rest
}: React.PropsWithChildren<any>) => {
  const { status, data: signInCheckResult } = useSigninCheck();
  console.log(signInCheckResult);
  debugger;
  if (status === "loading") {
    return <IonLoading isOpen={status === "loading"} />;
  }

  return (
    <Route
      {...rest}
      render={({ location }) =>
        signInCheckResult.signedIn === true ? (
          children
        ) : (
          <Redirect
            to={{
              pathname: "/login",
            }}
          />
        )
      }
    />
  );
};

From the ReactFire Example Code, see this is in AppAuthWrapper.tsx. The AuthWrapper code is from the reactfire repo to account for the removal of AuthCheck component

export const AuthWrapper = ({
  children,
  fallback,
}: React.PropsWithChildren<{ fallback: JSX.Element }>): JSX.Element => {
  const { status, data: signInCheckResult } = useSigninCheck();
  console.log(signInCheckResult);

  if (!children) {
    throw new Error("Children must be provided");
  }
  if (status === "loading") {
    return <IonLoading isOpen={status === "loading"} />;
  } else if (signInCheckResult.signedIn === true) {
    return children as JSX.Element;
  }

  return fallback;
};
