Server-Side Components

• server/Config.java: Handles configuration properties such as decryption keys and database credentials.
• server/Server.java: The main entry point of the server application, sets up routes for various functionalities and manages the server lifecycle.
• server/JwtManager.java: Manages JWT creation and validation for secure authentication.
• server/database/Database.java: Handles all database interactions, including user management, tweet storage, and direct messages.
• server/contexthandlers/: Contains HTTP request handlers for various endpoints such as /login, /signup, /edit, and /tweet.

Client-Side Components

• client/Client.java: The main entry point of the client application, which uses JavaFX for the UI.
• client/Requester.java: Handles HTTP requests to interact with the server for user authentication, timeline fetching, and social interactions.
• client/TweetCell.java: Manages the rendering of tweets, including retweets, replies, and polls, in the client UI.
• client/LikeEventHandler.java: Handles like/unlike actions for tweets.
