Getting Started 🚀

To run the chat app, you need to:

1. Clone this GitHub repo
2. Run the backend server
3. Run the frontend app

1. Clone this GitHub repo 📁

To clone this GitHub repo, open up your Terminal (MacOS) or Bash terminal (Windows) and navigate to wherever you want to save this repo on your local machine. Then, run:

git clone https://github.com/virattt/chat_app.git

2. Run the backend server 🖥️

Once you have this chat_app project cloned locally, navigate to the backend directory:

Create and activate a virtual environment:

python3 -m venv myenv

For MacOS/Linux:

source myenv/bin/activate

Make sure that you have Redis installed. You can find instructions here. Once installed, run redis:

If your backend server is running correctly, you should see something like this:
