Package Exports

gpt-json
gpt-json/lib/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (gpt-json) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Usage

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
//    area: 45339
// }

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' }]
    // Iteration 3: [{ height: 8848, name: 'Mount Everest' }, { height: 8611, name: 'K2' }]
    // etc.
  },
});

// Response:
// [
//   { height: 8848, name: 'Mount Everest' },
//   { height: 8611, name: 'K2' },
//   { height: 8586, name: 'Kangchenjunga' },
