MyMessage

MyMessage is a web-based WhatsApp-like application.

Description:

MyMessage app is the final project for CS50. It enables users to send and receive messages in a real-time chat environment and was built using the Flask framewok, also it includes 3rd party logging in with google and all messages are encrypted using asymmetric encryption. The project took approximately 3 weeks to complete and was both exciting and occasionally challenging 😅.

Getting started

git clone https://github.com/Maged-Zaki/MyMessage.git

cd MyMessage

python -m venv venv

On Windows

venv\Scripts\activate

pip install -r windows_requirements.txt

On MacOS

source venv/bin/activate

pip install -r macOs_requirements.txt

At this moment before we run the server we need download the secret_client file from google console.

1. After we create our google credentials, Download the secret_client file.
2. copy and paste the file into the root of the project.

Now we need to create config.py file at the root of the project

1. at the root of the project, create config.py
2. copy and paste the following then fill in the required configuration

# google client id from google_client_secret file
GOOGLE_CLIENT_ID = " 
CLIENT_SECRET_FILE_PATH = ""

# app secret
SECRET_KEY = "" 

# mail configuration
MAIL_USERNAME = ''
MAIL_PASSWORD = ''
MAIL_DEFAULT_SENDER = ''

Now we can start the server with the following command

flask run

Now the server is running Head to http://localhost:5000

That's it, we are done, we can now create an account and start messaging people!
