# Update February 1, 2023 <!-- omit in toc -->

This package no longer requires any browser hacks – **it is now using the official OpenAI API** with a leaked, unofficial ChatGPT model. 🔥

```ts
import { ChatGPTAPI } from 'chatgpt'

const api = new ChatGPTAPI({
  apiKey: process.env.OPENAI_API_KEY
})

const res = await api.sendMessage('Hello World!')
console.log(res.text)
```

The updated solution is significantly more lightweight and robust compared with previous versions.

If you run into any issues, we do have a pretty active [Discord](https://discord.gg/v9gERj825w) with a bunch of ChatGPT hackers from the Node.js & Python communities.

## 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...

## Install

```bash
npm install chatgpt
```

## Usage

Sign up for an [OpenAI API key](https://platform.openai.com/overview) and store it in your environment.

```ts
import { ChatGPTAPI } from 'chatgpt'

async function example() {
  const api = new ChatGPTAPI({
    apiKey: process.env.OPENAI_API_KEY
  })

  const res = await api.sendMessage('Hello World!')
  console.log(res.text)
}
```

If you want to track the conversation, use the `conversationId` and `id` in the result object, and pass them to `sendMessage` as `conversationId` and `parentMessageId` respectively.

```ts
const api = new ChatGPTAPI({ apiKey: process.env.OPENAI_API_KEY })

// send a message and wait for the response
let res = await api.sendMessage('What is OpenAI?')
console.log(res.text)

// send a follow-up
res = await api.sendMessage('Can you expand on that?', {
  conversationId: res.conversationId,
  parentMessageId: res.id
})
console.log(res.text)

// send another follow-up
// send a follow-up
res = await api.sendMessage('What were we talking about?', {
  conversationId: res.conversationId,
  parentMessageId: res.id
})
console.log(res.text)
```

You can add streaming via the `onProgress` handler:

```ts
// timeout after 2 minutes (which will also abort the underlying HTTP request)
const res = await api.sendMessage('Write me a 500 word essay on frogs.', {
  onProgress: (partialResponse) => console.log(partialResponse)
})
```

You can add a timeout using the `timeoutMs` option:

```ts
// timeout after 2 minutes (which will also abort the underlying HTTP request)
const response = await api.sendMessage('this is a timeout test', {
  timeoutMs: 2 * 60 * 1000
})
```

<details>
<summary>Usage in CommonJS (Dynamic import)</summary>

```js
async function example() {
  // To use ESM in CommonJS, you can use a dynamic import
  const { ChatGPTAPI } = await import('chatgpt')

  const api = new ChatGPTAPI({ apiKey: process.env.OPENAI_API_KEY })

  const res = await api.sendMessage('Hello World!')
  console.log(res.text)
}
```

</details>

### Docs

See the [auto-generated docs](./docs/classes/ChatGPTAPI.md) for more info on methods and parameters. Here are the [docs](./docs/classes/ChatGPTAPI.md) for the browser-based version.

### Demos

To run the included demos:

1. clone repo
2. install node deps
3. set `OPENAI_API_KEY` in .env

A [basic demo](./demos/demo.ts) is included for testing purposes:

```bash
npx tsx demos/demo.ts
```

A [demo showing on progress handler](./demos/demo-on-progress.ts):

```bash
npx tsx demos/demo-on-progress.ts
```

The on progress demo uses the optional `onProgress` parameter to `sendMessage` to receive intermediary results as ChatGPT is "typing".

A [conversation demo](./demos/demo-conversation.ts):

```bash
npx tsx demos/demo-conversation.ts
```

Lastly, a [persitence demo](./demos/demo-persistence.ts) shows how to store messages in Redis for persistence:

```bash
npx tsx demos/demo-conversation.ts
```

Any [keyv adaptor](https://github.com/jaredwray/keyv) is supported for persistence, and there are overrides if you'd like to use a different way of storing / retrieving messages.

Note that persisting message is very important for remembering the context of previous conversations.

## Compatibility

- This package is ESM-only.
- This package supports `node >= 14`.
- This module assumes that `fetch` is installed.
  - In `node >= 18`, it's installed by default.
  - In `node < 18`, you need to install a polyfill like `unfetch/polyfill`
- If you want to build a website using `chatgpt`, we recommend using it only from your backend API
