A swift and simple app made for NHS hospitals where you have quick, easy access to all the doctors and surgeons actively working to share all the secure media and chats safely
This App at high level works similarly to most widely used messengers like Whatsapp, imessenger, etc. the difference here is the contacts are only from all the hospitals bound with NHS in UK. About 150 hospitals have lots of doctors which can be easily searched within the app and they can also create groups within so that chat can be made easy for all the doctors involved in a single case.
Socket.io is widely used for chats and instant request/response architecture. Hence that was only challenge to bring on the chat system work swiftly with socket.io without any interruption. Along with that there was also session expiry for a chat session so that man in middle attacks can be avoided.
Implementation of socket.io library in iOS and android along with Node was solution. Node being an active instance will always remain in active state where clients will use socket.io to listen to each other.
