🔄 Refactor: Enhanced State Management

Overview

Improved the structure of the Redux store and API interactions to provide dynamic environment-based data handling and enhanced API interaction.

Key Highlights:

Dynamic Source Management (api.ts)

Enhanced data source selection mechanism to toggle between mock data and live API responses based on the NEXT_PUBLIC_DATA_SOURCE_TYPE environment variable to allow seamless switching of contexts, facilitating easier testing and debugging.

Redux Enhancements (store.ts, messagesSlice.ts, savedContentSlice.ts, and tagsSlice.ts)

Introduced new slices for better categorization and state management. Refactored existing slices to minimize side effects and improve modularity.

Type-Safe Hooks (hooks.ts)

Implemented custom Redux hooks (useAppDispatch, useAppSelector, useAppStore) to enhance type safety and simplify the Redux usage pattern across the application, making the codebase more maintainable and robust.

Best Practices Implemented:

• Segregated API calls and data processing into custom hooks for better reusability.
• Simplified components by abstracting non-UI logic into utility functions.
• Utilized TypeScript for enhanced type checking and code clarity.
• Enabled dynamic data source switching for adaptable testing and development environments.

✨ Feature: Chat and Category Enhancements

Overview

Major upgrades to provide a more engaging user interface. The introduction of categories within chats allows users to navigate through different topics effectively, improving the overall user experience and engagement.

Key Highlights

Category Interface Implementation (interfaces.ts)

Transitioned from a messages-centric state management to a chats-based approach, with a new Category interface added to categorize messages, facilitating a structured way to handle chat topics.

Asynchronous Actions

Introduced asynchronous actions to fetch and manage AI responses within chat contexts, ensuring real-time interaction and state updates.

Best Practices Implemented:

• Clearly defined types and interfaces for consistency across the application.
• Improved state management within Redux for asynchronous actions.
• Enhanced error handling within API interactions and UI components.
• Cleaned up legacy code to maintain codebase integrity and eliminate deprecated code.

✨ Feature: Robust Authentication System

Title: Implement Robust Authentication Flow and Session Management

Overview

Overhauled the authentication flow to enhance security and user experience, focusing on session management and OAuth enhancements.

Key Highlights

Auth Context (provider.tsx)

New authentication context for global state management. It provides essential functions and state variables to be accessible throughout the application to avoid prop drilling and ensure consistent user authentication state. It maintains context on session information, updating user state on sign-in or sign-out, and handles session persistence across page reloads.

OAuth Enhancements (callback/page.tsx)

Improved OAuth callback handling for secure redirection and session persistence. the component AuthCallback capturing essential tokens, and updates the local storage to maintain session state. Implements checks to navigate the user to the correct page depending on if they are authenticated or not, enhancing the security the login flow.

Best Practices Implemented

• Implemented consistent use of context for authentication across the app.
• Ensured robust session management.
• Enhanced security and user management.
• Improved user experience through secure authentication flow.

🔄 🔄 Refactor: Supabase Functions with CORS headers

Overview

Optimized CORS Handling in Supabase Functions

Key Highlights

CORS Standardization (server/supabase/functions/chat/index.ts):

Uniform CORS headers across responses for improved standards compliance.

✨ Feature: Supabase Chat Integration

Overview

Significant enhancement of chat functionalities through Supabase integration, boosting real-time capabilities and scalability.

Key Highlights:

API Refinement (api.ts)

Shifted to real-time data handling with Supabase for streamlined operations in real-time and scalability.

State Management (chatsSlice.ts)

Configured new chatsSlice for managing chat sessions and messages more effectively.

UI Loader Component (loader.tsx)

New visual component for indicating ongoing operations, enhancing user experience.

Best Practices Implemented:

• Utilized modern backend-as-a-service features to ensure scalability and reliability.
• Enhanced user feedback mechanisms with new UI components.

🧹 Chore: update package files

Dependency Management and Package Updates

Overview

Routine maintenance update to package files, removing outdated dependencies and introducing new packages for enhanced functionality.

Thank you Tanya, such a great work and very great PR description.

Just friendly suggestion for future developments: If you're creating very large PR like this, I think instead of putting all the changes inside single PR, creating multiple PRs would help reviewers to understand changes better. It's still understandable since you shared what each commit does, but creating multiple PRs can be another strategy.

Thanks!

Just a quick suggestion: if possible, could you please convert the dropdown button to an accordion when it is expanded and closed?

When it is closed, it should show a downward arrow (↓), and when it is expanded, an upward arrow (↑) so we can close the accordion.

If this takes a lot of time, feel free to merge your PR without this implementation. :)

[TanyaaCJain]

Thank you everyone for your comments. I have addressed the review comments received on this PR and merging it now. Thank you for such nice words :)

[TanyaaCJain]

@inhwaS I will look into your issue and create a github issue for the fix.
