General Resources:

Steps to get started

  2. Create a .env file on root folder
  3. Add a variable OPENAI_API_KEY=your_open_api_key
  4. Run npm i

Hints

Currently its using davinci-003. Due to the reduced max token size, I would always incorporate the tables that you want to include for your prompts.

You can to that by tweaking the code here:

includesTables: ['Products', 'Orders', 'Order Details'],

I am working on a solution to make it easier.

Ideas to enhance this project

  • Add reading git repos to search for particular solutions or libraries.
  • Add OpenAPI Chain to query against OpenAPI definitions.
