Code based on the MIT-licensed github project:

  https://github.com/hillis/gpt-4-chat-ui.git

Updated to work with openai v4.x Nodejs API

Then changed to work with a custom assistant that has been
'taught' about a collection based on exporting the
collection:

  export.pl -save_as OpenAIGPTs ...
  
Further changed so the ChatGPT GUI can be embedded in a Greenstone page.


To setup and run the code:

1. Make sure you have created a '.env' field in the top-level of
   this NodeJS project, and set the following lines accordingly
   with the relevant values from your OpenAI account:

----
OPENAI_API_KEY=sk-????????????????????????????????????????????????
ORGANIZATION_ID=org-????????????????????????
ASSISTANT_ID=asst_????????????????????????
----


2. Start the development server (defaults to port 3000) with:

  npm run dev


Now access:

   http://localhost:3000/


3. To run as a production server

  ./BUILD-PROD.sh
  ./START-PROD-NOHUP.sh
