## Intro
This package is a Node.js wrapper around [ChatGPT](https://openai.com/blog/chatgpt) by [OpenAI](https://openai.com). 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 ChatGPT to access it's unofficial REST API.
To get a session token:
1. Go to https://chat.openai.com/chat and log in or sign up.
2. Open dev tools.
3. Open `Application` > `Cookies`.
4. Copy the value for `__Secure-next-auth.session-token` and save it to your environment.
If you want to run the built-in demo, store this value as `SESSION_TOKEN` in a local `.env` file.
> **Note**
> This package will switch to using the official API once it's released.
> **Note**
> Prior to v1.0.0, this package used a headless browser via [Playwright](https://playwright.dev/) to automate the web UI. Here are the [docs for the initial browser version](https://github.com/transitive-bullshit/chatgpt-api/tree/v0.4.2).
## Install
```bash
npm install --save chatgpt
# or
yarn add chatgpt
# or
pnpm add chatgpt
```
## Usage
```ts
import { ChatGPTAPI } from 'chatgpt'
async function example() {
const api = new ChatGPTAPI({ sessionToken: process.env.SESSION_TOKEN })
// 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)
}
```
By default, the response will be formatted as markdown. If you want to work with plaintext only, you can use:
```ts
const api = new ChatGPTAPI({
sessionToken: process.env.SESSION_TOKEN,
markdown: false
})
```
A full [example](./src/example.ts) is included for testing purposes:
```bash
# 1. clone repo
# 2. install node deps
# 3. set `SESSION_TOKEN` in .env
# 4. run:
npx tsx src/example.ts
```
