## Intro



This package is a Node.js wrapper around Bing Chat by Microsoft. TS batteries included. ✨



> **Warning**

> This package is a reverse-engineered hack. I do not expect it to continue working long-term, and it is not meant for use in production. I'm building this in public, and you can follow the progress on Twitter [@transitive_bs](https://twitter.com/transitive_bs).



## Demo





  Example conversation

  (30s conversation demo)




## Install



```bash

npm install bing-chat

```



Make sure you're using `node >= 18` so `fetch` is available.



## Usage



**You need access to Bing Chat OR a valid cookie from someone who has access**.



The cookie you need from Bing is the `_U` cookie (or just all of the cookies concatenated together; both will work).



```ts

import { BingChat } from 'bing-chat'



async function example() {

  const api = new BingChat({

    cookie: process.env.BING_COOKIE

  })



  const res = await api.sendMessage('Hello World!')

  console.log(res.text)

}

```



You can follow-up messages to continue the conversation. See `demos/demo-conversation.ts` for an example.



Note that Bing Chat conversations expire after about 20 minutes, so they're not meant to be long-term objects.



You can add streaming via the `onProgress` handler:



```ts

const res = await api.sendMessage('Write a 500 word essay on frogs.', {

  // print the partial response as the AI is "typing"

  onProgress: (partialResponse) => console.log(partialResponse.text)

})



// print the full text at the end

console.log(res.text)

```



See `demos/demo-on-progress.ts` for a full example of streaming support.



You can also add the the parameter `variant` to the `sendMessage` function to change the variant of the AI. The default is `Balanced`, but you can also use `Precise` or `Creative`.



```ts

const res = await api.sendMessage('Write a 500 word essay on frogs.', {

  // change the variant to 'Precise'

  variant: 'Creative'

})

```



## Projects



If you create a cool integration, feel free to open a PR and add it to the list.



## Compatibility



- This package is ESM-only.

- This package supports `node >= 18`.

- This module assumes that `fetch` is installed globally.

- If you want to build a website using `bing-chat`, we recommend using it only from your backend API
