Usage

Programmatically create prompts and receive responses from Bing API.

import {
  BingasaurusClient,
  Types,
} from "https://deno.land/x/bingasaurus@v<version>/mod.ts";

// create a BingasaurusClient
const client = new BingasaurusClient({
  _U_cookie: USER_COOKIE,
});

// create a conversation
const conv = client.createConversation();

// send messages for that conversation
const resp1 = await conv.sendMessage("Hi, how are you today?");
const resp2 = await conv.sendMessage("How do you think Bard is doing today?");

BingMessageResponse

To give access to the entire response message the .sendMessage function resolves with a promise that includes a text string and a raw object.

const resp = await conv.sendMessage("Hi, how are you today?");

console.log(resp.text);
// I'm doing well, thank you for asking. 😊 I hope you are having a good day too.

console.log(resp.raw);
/*
{
  "type": 2,
  "invocationId": "1",
  "item": {
    "messages": [
      {
        "text": "How are you doing today?",
        ...
       {
        "text": "I'm doing well, thank you for asking. 😊 I hope you are having a good day too.",
        "author": "bot",
*/

BingConversationOptions

Resume a conversation by entering the conversationId, clientId and conversationSignature.

interface BingConversationOptions {
  conversationId?: string;
  clientId?: string;
  conversationSignature?: string;
  userToken: string;
  onUpdateMessage?: OnUpdateMessage;
  otherHeaders?: HeadersInit;
}

const client = new BingasaurusClient({
  _U_token: USER_COOKIE,
});

const conv = client.createConversation({
  conversationId: "1234",
  clientId: "1234",
  conversationSignature: "1234",
});

BingMessageOptions

Customize the options when sending a message to Bing.

type BingMessageOptions =
  | Partial<SydneyQueryOptions>
  | Partial<ChatRequestHubOptions>;

interface SydneyQueryOptions {
  conversationId: string;
  clientId: string;
  conversationSignature: string;
  invocationId: string;
  messageType?: UserMessageType;
  variant?: Variant; // Default Variant is 'h3imaginative' which uses GPT-4
  locale?: string;
  market?: string;
  region?: string;
  location?: {
    lat: number | string;
    lng: number | string;
    re?: string;
  };
  onUpdateStatus?: OnUpdateStatus;
  onMessage?: onMessage;
  isStartOfSession?: boolean;
}

interface ChatRequestHubOptions {
  onUpdateStatus?: OnUpdateStatus;
  onMessage?: onMessage;
  onRawMessage?: onRawMessage;
}

const client = new BingasaurusClient({
  _U_token: USER_COOKIE,
});

const conv = client.createConversation();

const message = await conv.sendMessage(
  "Write a short poem about AI helping lawyers.",
  {
    variant: "h3precise",
    onUpdateStatus: (update: ChatRequestStatusUpdate) => {
      if (update.status !== ChatHubStatus.WRITING) {
        console.clear();
        console.log(update.text);
      }
    },
  },
);

Example

const client = new BingasaurusClient({
  _U_cookie: USER_COOKIE,
});

const conv = client.createConversation(JSON.parse(config));

const prompt = `
Can you generate a weather report for Sydney Australia using this yaml as a template?

\`\`\`

date: <iso-string>

`;

const resp = await conv.sendMessage(prompt);
const startYaml = resp.text.indexOf("```");
const endYaml = resp.text.indexOf("```", startYaml + 1);
const report = resp.text.slice(startYaml + 3, endYaml);
Deno.writeTextFileSync(report, "report.yaml");

await conv.sendMessage("Now can you do that for Canberra?");
