Building Agents Using Langgraph TS

Consider giving this repo a ✨! Thanks!!!

Prerequisites

You need to have the following tools installed:

• NodeJS
• PNPM
• Inferix or any OpenAI compatible API.

Environment Setup

1. Setup the project

# To install all dependencies
pnpm install

2. Install Inferix (OpenAI compatible API)

• Feel free to use OpenAI or any OpenAI compatible server.
• Use this guide to setup inferix to host a OpenAI compatible API capable of function calling.

3. Set the environment variables

• INFERIX_BASE_URL
• INFERIX_API_KEY

You can change these by updating the ./src/utils/models.ts file.

Run The App

We got 4 scripts in this project:

1. pnpm run 00 - Making a simple inference call using langchain js.
2. pnpm run 01 - Running an langgraph equivalent of the above step.
3. pnpm run 02 - Add support for function/tool calling in langgraph
4. pnpm run 03 - A full feldged langgraph app.

You can try running the final script with the following inputs:

• Get me all my tasks - It will list and summarize all your tasks.
• I got my groceries - It marks the "Buy groceries task as done."
• I finished watching all episodes from Naruto - It doesn't do anything cause such a task doesn't exist.
