React app UI talking to OpenAI REST endpoints

Caution - this is just a demo - there is practically no error checking ! Some of the config is hardcoded (I will get to it sometine !).

This is a simple/toy REST service in Node.js and Express using OpenAI API for converting and scaling weights and measures (it can be used for other purposes with a few changes). It is rendered using a React UI compoment.

You will need Node.js and npm

Get OpenAI API key (check References towards the end). Copy .env.example to .env and add the API key there.

Do an npm install and run with npm start. This will start a local REST service on port 4000 and a React web UI on port 3000.

The React web UI can be accessed on a browser by going to http://localhost:3000. The React UI will talk to the backend REST services and update the UI with results.

To try the backend REST service without React UI; it should be possible to test some weights and measures scaling REST endpoint with something like:

http://localhost:4000/scaleWeightsAndMeasures?quantity=20&fromUnit=ounces&toUnit=milliliters&scaleFactor=2

from a browser.

OR

curl 'http://localhost:4000/scaleWeightsAndMeasures?quantity=20&fromUnit=ounces&toUnit=milliliters&scaleFactor=2'

from commandline.

It will comeup with an answer like:

{"scaledValue":"Answer: 40 ounces is equal to 1136.5225 milliliters"}
