This repository contains all of the starter code needed to run an LLM-powered chat app on your local machine:

1. Django backend
2. React TypeScript frontend
3. LangChain Agents and LLMs

To run the chat app, you need to:

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

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

Make sure that you have git installed (instructions).

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

cd ~/path_to/chat_app/backend

Create and activate a virtual environment:

python3 -m venv myenv

For MacOS/Linux:

source myenv/bin/activate

For Windows:

myenv\Scripts\activate

Install the necessary libraries:

pip install -r requirements.txt

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

redis-server

Run the backend server:

daphne project.asgi:application

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

"WSCONNECTING /ws/chat/" - -
"WSCONNECT /ws/chat/" - -

Important: In order to run the LLM, set your Open AI API key here.

In a new Terminal window (or tab), navigate to the frontend directory:

cd ~/path_to/chat_app/frontend

Make sure that you have Node and npm installed (MacOS instructions and Windows instructions)

Install the necessary packages:

npm install

Run the frontend app:

npm start

If successful, your browser should open and navigate to https://localhost:3000/. The chat app should load automatically.
