Nstbrowser SDK for Node.js ​

A Node.js SDK for interacting with Nstbrowser API v2

Note: This documentation is for API v2, which is the recommended version with complete functionality from v1 plus additional features. For v1 documentation, please refer to README-v1.md. New users are encouraged to use v2 for a more stable and standardized experience.

Overview ​

This SDK implements Nstbrowser API v2, providing a comprehensive set of tools for managing browser profiles, controlling browser instances, managing local browser data, and utilizing Chrome DevTools Protocol (CDP) for browser automation.

The SDK enables you to:

• Create and manage browser profiles with detailed fingerprint configurations
• Start and stop browser instances individually or in batch
• Configure and manage proxies for profiles
• Manage profile tags for better organization
• Clear browser cache and cookies
• Connect to browsers using Chrome DevTools Protocol (CDP)
• Automate browser actions through CDP integration with Puppeteer

Installation ​

Using npm:

$ npm install nstbrowser-sdk-node

$ npm install nstbrowser-sdk-node

Using pnpm:

$ pnpm install nstbrowser-sdk-node

$ pnpm install nstbrowser-sdk-node

Using yarn:

$ yarn add nstbrowser-sdk-node

$ yarn add nstbrowser-sdk-node

Getting Started ​

To use the SDK, you need an API key from Nstbrowser:

import { NstBrowserV2 } from 'nstbrowser-sdk-node';

// Initialize the client with your API key
const client = new NstBrowserV2('your_api_key', {
  timeout: 60000,
  apiAddress: 'http://localhost:8848/api/v2'
});

// Now you can use the various services
const profileId = 'your_profile_id';

// Start a browser instance
const startResponse = await client.browsers().startBrowser({ profileId });
console.log('Browser started:', startResponse);

// Stop the browser instance
const stopResponse = await client.browsers().stopBrowser({ profileId });
console.log('Browser stopped:', stopResponse);

import { NstBrowserV2 } from 'nstbrowser-sdk-node';

// Initialize the client with your API key
const client = new NstBrowserV2('your_api_key', {
  timeout: 60000,
  apiAddress: 'http://localhost:8848/api/v2'
});

// Now you can use the various services
const profileId = 'your_profile_id';

// Start a browser instance
const startResponse = await client.browsers().startBrowser({ profileId });
console.log('Browser started:', startResponse);

// Stop the browser instance
const stopResponse = await client.browsers().stopBrowser({ profileId });
console.log('Browser stopped:', stopResponse);

CDP Integration with Puppeteer ​

One of the most powerful features of the SDK is its seamless integration with Puppeteer for browser automation:

import { NstBrowserV2 } from 'nstbrowser-sdk-node';
import puppeteer from 'puppeteer-core';

async function automateWithPuppeteer() {
  const client = new NstBrowserV2('your_api_key');
  
  // Connect to a browser using CDP
  const cdpResponse = await client.cdpEndpoints().connectBrowser({
    profileId: 'your_profile_id',
    config: {
      headless: false,
      autoClose: false
    }
  });

  // Connect Puppeteer to the browser instance
  const browser = await puppeteer.connect({
    browserWSEndpoint: cdpResponse.data.webSocketDebuggerUrl,
    defaultViewport: null
  });

  // Use Puppeteer for automation
  const page = await browser.newPage();
  await page.goto('https://example.com');
  
  // ... perform other actions
}

import { NstBrowserV2 } from 'nstbrowser-sdk-node';
import puppeteer from 'puppeteer-core';

async function automateWithPuppeteer() {
  const client = new NstBrowserV2('your_api_key');
  
  // Connect to a browser using CDP
  const cdpResponse = await client.cdpEndpoints().connectBrowser({
    profileId: 'your_profile_id',
    config: {
      headless: false,
      autoClose: false
    }
  });

  // Connect Puppeteer to the browser instance
  const browser = await puppeteer.connect({
    browserWSEndpoint: cdpResponse.data.webSocketDebuggerUrl,
    defaultViewport: null
  });

  // Use Puppeteer for automation
  const page = await browser.newPage();
  await page.goto('https://example.com');
  
  // ... perform other actions
}

Examples ​

The SDK comes with a comprehensive set of examples in the /examples/v2 directory. To run the examples:

1. Navigate to the examples directory and install dependencies:

cd examples/v2
npm install

cd examples/v2
npm install

2. Create a .env file in the examples/v2 directory and add your API key:

echo "nstbrowser_api_key=your-api-key" > .env

echo "nstbrowser_api_key=your-api-key" > .env

3. Run any example:

node browsers/startBrowser.js

node browsers/startBrowser.js
