How to use Google Bard Unofficial API in JavaScript

Recently, we've talked about using Bard AI using Python

And here is how to do using it in a JavaScript environment.

It doesn't have any Node.js dependency and uses native fetch for fetching API calls. So it should work on any environment like browser/node/deno.

FYI: This is a community package reverse-engineering Google Bard web app so don't use it in any production environments

Getting Auth Cookie from Bard web app

As for the authentication part, we'll be using cookie value from the Bard web app.

We'll need to get __Secure-1PSID cookie value from Bard

Dependency

We need to install bard-ai using pip

npm install bard-ai

Snippet - Google Bard API

import Bard, { askAI } from "bard-ai";
const COOKIE_KEY = '...' // Your __Secure-1PSID here
console.log(await askAI("Say hello in Tamil"));

For other advanced use cases, you can refer to their docs

Happy chatting-with Bard!
