Create a Chat Application using Angular, Flask, and Socket.IO

In this project, we’ll build a real-time chat application using Angular, Flask, and Socket.IO that will include a chat history storing feature using SQLite.

Create a Chat Application using Angular, Flask, and Socket.IO

You will learn to:

Use Socket.IO to facilitate real time communication in a web application.

Use SQLite3 to store and retrieve user chats.

Implement user management using Flask and Angular.

Use the socket.io-client library in Angular for the client-side implementation of Socket.IO.

Project Description

The Socket.IO library is a powerful tool that facilitates seamless real-time communication between clients and servers. We'll create an engaging chat application where each user will have their own account after completing the registration process. This personalized account will grant access to the application after logging in. The application will enable the logged-in users to look for other online users and start a chat with anyone they want. Moreover, the users will be able to see the list of users they’ve previously conversed with. They will also have access to the chat history with each user.

In this project, we'll set up the backend using Flask, a famous Python framework for web development. The front-end implementation of Socket.IO and Flask will be done using Angular and Material UI. We will also handle database-related operations using SQLite, a file-based SQL database that can be connected using the sqlite3 Python module.

Here is the complete layout of the application:
