We have migrated all agent functionality from LangChain Typescript to LangChain Python. Thus you will need to run the Langchain UI API in order to interact with the chatbot. In the future when the TS package is on par with the Python package we will migrate to only using Javascript.

1. Setup the Langchain UI API

2. Clone the repo into a public GitHub repository (or fork https://github.com/homanp/langchain-ui/fork). If you plan to distribute the code, keep the source code public.

   git clone https://github.com/homanp/langchain-ui.git

3. Go to the project folder

   cd langchain-ui

4. Install packages with npm

   npm install

5. Set up your .env file

   • Duplicate .env.example to .env

6. Run the project

   npm run dev

7. Run the linter

   npm run lint
