Requirements

• Python ^3.10
• Poetry (optional)
• Node.js >=16
• Yarn (optional: npm can be used instead)
• make (optional: jump to Slow start if you don't have it)

Quick start

If you have all the requirements installed, you can run the following commands to start the app.

# Setup all the things
make setup

# Run all the things
make runall
# Or if you installed tmux
make tmux

# Run the backend
make backend

# Run the frontend
make frontend

Slow start

If you don't have make installed, you can follow the steps below to start the app.

1. Environment variables

# Create a .env.local file
cp .env.local.example .env.local

And fill in the values for the environment variables.

2. Setup the backend

Launch the backend server first.

Or

cd backend

# Download necessary packages
poetry install
# or
pip install -r requirements.txt

# Start your backend server
poetry run uvicorn api.conversation_chain:app --reload
# or
python uvicorn api.conversation_chain:app

3. Setup the frontend

Open up another terminal (tab or window) and keep your backend running.

# In the new terminal cd into the next-app directory
cd frontend

# Install all dependencies
yarn install

# Start your frontend app
yarn dev

Opening http://localhost:3000/ in your browser should now show your frontend Next.js app.

Shell script for starting frontend and backend at the same time using tmux

Requirement: Unix like shell, zsh or bash; tmux installed.

In project folder "my_langchain_pa", you can use rundev.sh to start the app.

./rundev.sh

backend playground

When you successfully launch the backend server, you can visit http://localhost:8000 to use the playground.
