authentication with Firebase Auth and JWT (#35)

# Authentication with Firebase Auth and JWT ## ♻️ Current situation & Problem Please refer to these two discussion posts for context: https://github.com/orgs/CS342/discussions/78. https://github.com/orgs/CS342/discussions/83 ## ⚙️ Release Notes Modifications has been made to Prisma/Chat/ChatView 1. We generated JWT token in app in the `signInWithFirebase` function: `token = try await Auth.auth().currentUser?.getIDToken()`. 2. Then, the token is sent to the frontend via a URL parameter: `if let url = URL(string: "http://localhost:3000?token=\(token)")` Successful implementation is reflected by passing a JWT token from Swift to the web chat interface, which connects to the python backend and prints "user successfully authenticated via JWT". ## 📚 Documentation See in-line documentation ## ✅ Testing This codebase has not been thoroughly tested. We will address the stylistic requirements later. ## 📝 Code of Conduct & Contributing Guidelines By submitting creating this pull request, you agree to follow our [Code of Conduct](https://github.com/CS342/.github/blob/main/CODE_OF_CONDUCT.md) and [Contributing Guidelines](https://github.com/CS342/.github/blob/main/CONTRIBUTING.md): - [x] I agree to follow the [Code of Conduct](https://github.com/CS342/.github/blob/main/CODE_OF_CONDUCT.md) and [Contributing Guidelines](https://github.com/CS342/.github/blob/main/CONTRIBUTING.md). --------- Co-authored-by: bryant-jimenez <[email protected]> Co-authored-by: Paul Schmiedmayer <[email protected]> Co-authored-by: Dhruv Naik <[email protected]>
