Setup Instructions

This repo requires Node.js version 20+ or bun v1.0.20.

The main branch contains the final application. To code along with the workshop, checkout the step/1 branch. You will also need an API Key from OpenAI.

git clone https://github.com/Hendrixer/agent-from-scratch.git
cd agent-from-scratch
git checkout step/1
npm install # or bun install

To run the project:

npm start
# or
bun run index.ts

OpenAI API Key

Create an API Key from OpenAI and save it in a .env file:

OPENAI_API_KEY='YOUR_API_KEY'

OpenAI requires you to add a minimum of $5 USD credit to your account. Go to the billing page and add credits.

Note

It can take up to 20 minutes for the credits to be available via the API. So if you get an insufficient_quota error, try again in a few minutes.
