Intro

This package is a Node.js wrapper around ChatGPT by OpenAI. TS batteries included. ✨

You can use it to start building projects powered by ChatGPT like chatbots, websites, etc...

How it works

This package requires a valid session token from OpenAI's ChatGPT webapp to access it's unofficial REST API.

Go to https://chat.openai.com/chat and log in or sign up
Open the dev tools console
Open Application > Cookies
Copy the value for __Secure-next-auth.session-token and save it to your environment.

If you want to run the built-in demo,

Note This package will switch to using the official API once it's released.

Note Prior to v1.0.0, this package used headless Chromium via Playwright to automate the web UI. Here are the docs for the initial browser version.

Install

npm install --save chatgpt
# or
yarn add chatgpt
# or
pnpm add chatgpt

Usage

import { ChatGPTAPI } from 'chatgpt'

async function example() {
  const api = new ChatGPTAPI()

  // ensure the API is properly authenticated (optional)
  await api.ensureAuth()

  // send a message and wait for the response
  const response = await api.sendMessage(
    'Write a python version of bubble sort. Do not include example usage.'
  )

  // response is a markdown-formatted string
  console.log(response)
}

A full example is included for testing purposes:

# 1. clone repo
# 2. install node deps
# 3. set `SESSION_TOKEN` in .env
# 4. run:
npx tsx src/example.ts
