What third-party social providers are mentioned for Firebase authentication?

The video specifically mentions GitHub as a third-party social provider for Firebase authentication.

How does the real-time Firestore database update the UI?

The real-time Firestore database updates the UI by listening to live updates and storing the latest data, which is then reflected in the user interface.

What is the purpose of the cloud function demonstrated in the video?

The cloud function is used to create a user document in the database every time a user signs up, capturing their personal information from their GitHub profile.

How is the user's vote on the pineapple question stored in Firestore?

The user's vote is stored in a document within the 'votes' collection of Firestore, with the document name being the user's UID, and the vote value being the user's choice.

What is the role of the 'react-firebase-hooks' library in the project?

The 'react-firebase-hooks' library provides hooks that wrap around Firebase's core features, such as authentication and Firestore, to simplify their integration into React components.

How does the video guide the setup of Firebase Authentication?

The video guides the setup of Firebase Authentication by enabling GitHub authorization in the Firebase console, creating a GitHub application for OAuth, and setting up the frontend using 'react-firebase-ui'.

What is the significance of the 'emv.local' file in the project?

The 'emv.local' file is used to store environment variables, such as Firebase configuration values, to keep sensitive information secure and not expose it to users.

How is the user's sign-in state detected in the video?

The user's sign-in state is detected using the 'useAuthState' hook from the 'react-firebase-hooks' library, which provides the current signed-in user or undefined if not signed in.

What does the video suggest for organizing the code for better readability?
