AccountSection

AccountSection is a component which handles logging in and out on the website. It displays a prompt to log in if the user is not logged in, and if the user is logged in, it displays account details, including whether the user is an admin.

Props used:

  • fbAuth: a Firebase authentication object. This should be handed down from the App.js component.
  • fbProvider: a Firebase provider object. This should be handed down from the App.js component.
  • db: a Firestore database object. Used to check whether the user is an admin or not.
  • currentUser: the current user object. Used to display information pertaining to the user.
  • setCurrentUser: updates the current user object. Used when logging in/out.
  • isUserAdmin: indicates if the user is an admin.
    • Please note that this does not truly affect what the user is able to do with writing permissions, as if a user’s account is not really an admin account, their attempts to write to the Firestore will be rejected regardless of this variable’s value.
  • setIsUserAdmin: sets the indicator for if the user is an admin.

Functions implemented:

  • onAuthStateChanged: Calls a callback function whenever the state of the authentication object is changed (i.e. log in, log out, etc.).
    • The callback function used in this component checks whether there is a user logged in, and if there is, grabs whether they’re an admin, and sets the isUserAdmin state, as well as the currentUser state.
    • If the user is not logged in, it sets isUserAdmin to false, and sets currentUser to undefined.
    • Please note that this function is simply called in this file, and not actually created. However, its call contains a callback function which is implemented in this file.

Noteworthy components used:

  • LoggedInSection: A component displayed if the user is logged in (checked by whether currentUser has a value). More information in the LoggedInSection section of this page.
  • LogInSection: A component displayed if the user is not logged in. More information in the LogInSection section of this page.

  • isUserAdmin: indicates if the user is an admin.

Notes:

  • This component will make a pop-up for logging in via Google. This component doesn’t need to set the current user because the authorization object state change handles this on its own in the AccountDetails component.
