This repository contains all of the starter code needed to run an LLM-powered chat app on your local machine:
- Django backend
- React TypeScript frontend
- LangChain Agents and LLMs
To run the chat app, you need to:
- Clone this GitHub repo
- Run the backend server
- 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:
