Health Link is a cutting-edge platform designed to provide a virtual bridge between patients and doctors, offering remote medical consultations and a comprehensive suite of features tailored to enhance the healthcare experience. With the platform, patients can easily search for and select doctors by name or specialization, request video consultations, and receive personalized medical records post-consultation. This system not only ensures that patients receive timely and efficient healthcare services from the comfort of their homes but also significantly reduces the risk of exposure to contagious diseases in hospital settings.

• Users: Health Link caters to three types of users: patients, doctors, and administrative staff. It allows registered users to log in, while new users can sign up as patients.
• Doctor Selection and Consultation: Patients can search for and select doctors based on specialization or name. They can request video consultations, during which doctors can access the patient's medical records to aid in diagnosis.
• Medical Records: After consultations, patients receive medical records containing advice or treatment plans. Doctors have the capability to view, edit, and delete medical records for their patients.
• User Profiles: All registered users can view and modify their profiles. Administrative staff are responsible for managing doctor profiles within the system.

• Frontend: The client-side of the website is built using React and TailwindCSS, offering a responsive and user-friendly interface.
• Backend: The server-side utilizes Node.js and Express for RESTful API services.
• Real-time Communication: Socket.io is employed to manage online/offline statuses of doctors, facilitating real-time interactions. It supports features like online presence indicators and private consultation rooms.
• Video Consultations: The integration of WebRTC and PeerJS enables high-quality video consultations, with PeerJS simplifying the peer-to-peer connection setup.
• Database: MongoDB, along with the Mongoose library, is used for data storage, providing a flexible and scalable solution for managing user data and medical records.
