🌟 Introduction

Live chat allows users to send and receive messages in real-time. It is built using a microservices architecture, JWT verification and Websockets. The purpose of the project is to demonstrate my ability to build API's and manage non-relational databases.

🚀 Features

• 🔐 User authentication and authorization
• 📨 Real-time messaging
• 📇 Contacts management
• 🔗 Connection management
• 🗄️MongoDB for data storage

🏛️ Architecture

The application is composed of several microservices, each responsible for a specific functionality. The services communicate with each other using HTTP and WebSockets. Below is an overview of the architecture:

• 🔑 Login Service: Handles user login and token generation.
• ✅ Verification Service: Manages token verification processes.
• 📇 Contacts Service: Manages user contacts.
• 💬 Messages Service: Manages the sending and downloading of messages.
• 🔗 Connection Service: Manages WebSocket communications to enable real time chat conversations.
• 🗄️ MongoDB Database: Stores all persistent data for the application.

🛠️ Technologies

• FastAPI: Back-end framework for building APIs.
• MongoDB: NoSQL database for storing application data.
• Docker: Containerization of services.
• JWT: JSON Web Tokens for user authentication.
• WebSockets: Real-time communication protocol.
