Communicator App

Simple communicator app that allow sending text messages (and other attachments in future) in real time connection and saving conversation history.

How does it works

1. User is able to create new account protected by basic auth security (cridentials: login and password)
2. When user is trying to log in, server generate JWT, based on user's cridentials, wchich is stored in session in client app
3. JWT is sent in every request via http header
4. When deserialized token is correct (Spring Security filter chain returns positive result), user is able to use server's REST API e.g. send message
5. Sending messages process:
1. When user fill message's editor input field and press send button, message is stored in database by http post method
2. In same time, both participants of conversation subscribes appropriate websocket connection.
3. For that moment, users are able to sending messages in real time, simultaneously storing history of conversation in DB
