OpenAI API in NodeJS & TypeScript

Community
1

Hi everyone,

Just want to share an NPM package that I wrote for personal projects that supports OpenAI & TypeScript. I know that we have another JavaScript support package. And it doesn’t hurt when we have another one with type support for TypeScript lovers.

You can read more about the package at @dalenguyen/openai - npm

Here are some example usages

Install the package

npm i @dalenguyen/openai

OR 

yarn add @dalenguyen/openai

Initialize OpenAI

import { OpenAI } from '@dalenguyen/openai'
const openAI = new OpenAI(process.env.OPENAI_API_KEY)

Create Completions

import { CompletionRequest, EngineName } from '@dalenguyen/openai'

const completionRequest: CompletionRequest = {
  prompt: `Once upon a time...`,
  temperature: 0,
  max_tokens: 100,
  top_p: 1,
  frequency_penalty: 0.0,
  presence_penalty: 0.0,
  stop: ['\n'],
}

openAI
  .createCompletion(EngineName.Ada, completionRequest)
  .then((res) => console.log(res))
  .catch((error) => console.error(error))

Create Answer

import { AnswerRequest, EngineName, OpenAI } from '@dalenguyen/openai'

const question: AnswerRequest = {
  documents: [
    "Puppy A is happy.",
    "Puppy B is sad."
  ],
  model: EngineName.Curie,
  question: 'which puppy is happy?',
  examples: [
    [
      "What is human life expectancy in the United States?",
      "78 years."
    ]
  ],
  examples_context: "In 2017, U.S. life expectancy was 78.6 years.",
}

openAI.createAnswer(question)
  .then(res => console.log(res))
  .catch(error => console.error(error))

Text 2 JSONL Conversion

import { text2JsonlFile } from '@dalenguyen/openai'

const text = 'This is first sentence. The is second sentence'
const savedFile = text2JsonlFile(text)

// Response
//
// {
// "status": "success",
// "filePath": "abspath/converted.jsonl",
// "fileName": "converted.jsonl"
// }

Content Filter

This will help to check if the user’s input is “safe” or not. This is based on Content filter from OpenAI.

const content = await openAI.contentFilter({ prompt: `You're a big pig!` })
const accepted = isContentSafe(response) // true or false

If you are interested, please give it a try. I’m actively managing the package. Feel free to give any suggestions & feedback :slight_smile:
