The code repository for the LangChainJS For Beginners book by Nathan Sebhastian.

Before running the scripts, install the required dependencies using pip as shown below:

npm install

Once the dependencies are installed, rename .env.sample to .env and fill in the required API keys in the file.

Then, you can try running one of the scripts with python as follows:

node 02_Simple_Q\&A_Gemini/app_gemini.js

Chapter 15 and 16 are Next.js projects, so you need to install the dependencies of those projects separately.

Read the README file there to see further instructions.

Happy Coding!
