Initialization

import GPTJSON from 'gpt-json';
import { object, number } from 'yup';

const client = new GPTJSON({
  apiKey: 'YOUR_OPENAI_API_KEY', // Your OpenAI API key
});

Non-streamed request

const response = await client.executeRequest({
  model: 'gpt-4', // OpenAI's model
  request: 'Give me some basic data about Estonia', // Your request that targets the GPT API
  schema: object({
    population: number(),
    area: number().meta({ description: 'Area in square kilometers' }), // Use descriptions to get more consistent responses. E.g. you can define the unit of measure to prevent metric/imperial system issues.
  }),
});

// Response:
// {
//    population: 1331000

Streamed request

const response = await client.executeStreamRequest({
  model: 'gpt-4',
  request: 'Top 5 tallest mountains of the world',
  schema: array(
    object({
      height: number().required(),
      name: string().required(),
    })
  ),
  // It is only called when the data can be validated with the defined schema
  onUpdate: data => {
    console.log(data);
    // Iteration 1: []
    // Iteration 2: [{ height: 8848, name: 'Mount Everest' }]

    // etc.
