Connect with jsx about react-native-axios-jwt

I don’t see how this library has anything to do with react navigation or conditional rendering.

Thanks for this awesome tool! I'm facing the same issue @c0nsoleg tho: there is no way to react to when the user gets logged in or logged out in order to do something like:

const isLoggedIn = useIsUserLoggedIn();

if (isLoggedIn) {
  return <HomeNavigation />;
}

return <AuthNavigation />;

You can answer with "this library is just for setting the axios headers interceptors" and you would be 100% right, but at the same time it would be nice to have the possibility to respond accordingly.

Thanks!

Hi @ericlifs, have you tried using the isLoggedIn function that is exported from this library? Check out the readme to learn how to use this library.

Hey @mvanroon, how are you? Yes, I've tried using that isLoggedIn function but it doesn't fit our requirement as it is an async function that returns a boolean indicating whether the user is logged at the time of calling the function or not. We were talking about having a hook that returns a boolean indicating when the headers are set or not, by doing that you can react to changes on this boolean and show different navigators accordingly.

Also, there is a "bug" in the readme file: this is the code for the isLoggedIn function:

/**
 * Checks if refresh tokens are stored
 * @async
 * @returns {Promise<boolean>} Whether the user is logged in or not
 */
export const isLoggedIn = async (): Promise<boolean> => {
  const token = await getRefreshToken()
  return !!token
}

If you do in your code:

if (isLoggedIn()) {
  console.log('logged in')
} else {
  console.log('not logged in')
}

It will always show 'logged in' because the isLoggedIn function is an async function and therefore returns a Promise<boolean> which is always true (you'll always need to await that call).

Eric.

You’re right! Looks like the readme needs to be updated. Could you open a PR?

As for ‘caching’ the auth state. You could build this in your own project or we could create a hook that returns the logged in state. This state would need to be updated when a user logs in or out.

Wanna take a stab at it? I’m available for reviewing pull requests.
