Message App with WebSocket and JWT authentication

💡 Overview

The Message App is a project developed for real time exchange of messages. It has multiple technologies for authentication, exchanging of messages using socket and API development for CRUD.

✨ Features

• 🔐 User Authentication: Secure login with JWT Token and expiring token.
• 🌎 Chat rooms: Chat rooms using socket.io to exchange messages safely.
• 📄 Databases: CRUD technology using MySQL and sequelize to store password hashes, conversation messages and more.
• 🔍 Creating messages and filtering users: Create message as groups or individuals and search for the users you want to assign.
• 🖥️ API Restful: Rest APIs developed to manage conversations, users, chatrooms and others.
• ❗ Disclaimer: In the backend, Im not using .env file to setup variables so people can check on passwords, ports and etc., however in a real project it's higly recommended to do so and do not save confidential variables in the code.
