Bright Data Reference Architecture

Overview

Production-ready architecture for Bright Data scraping systems. Covers project layout, data pipeline design, and integration patterns for Web Unlocker, Scraping Browser, SERP API, and Datasets API.

Prerequisites

Understanding of layered architecture
Node.js/TypeScript project setup
Database for storing scraped data

Key Components

Step 1: Multi-Product Client

// src/brightdata/client.ts
import axios, { AxiosInstance } from 'axios';
import https from 'https';
import { chromium } from 'playwright';

export class BrightDataClient {
  private proxyClient: AxiosInstance;
  private apiToken: string;

  constructor(private config: {
    customerId: string;
    zone: string;
    zonePassword: string;
    apiToken: string;
  }) {
    this.apiToken = config.apiToken;
    this.proxyClient = axios.create({
      proxy: {
        host: 'brd.superproxy.io',
        port: 33335,
        auth: {
          username: `brd-customer-${config.customerId}-zone-${config.zone}`,
          password: config.zonePassword,
        },
      },
      httpsAgent: new https.Agent({ keepAlive: true, rejectUnauthorized: false }),
      timeout: 60000,
    });
  }

  // Web Unlocker — simple HTTP through proxy
  async scrape(url: string, country?: string): Promise<string> {
    const response = await this.proxyClient.get(url);
    return response.data;
  }

  // Scraping Browser — Playwright over CDP
  async scrapeWithBrowser(url: string, extract: (page: any) => Promise<any>) {
    const auth = `brd-customer-${this.config.customerId}-zone-scraping_browser1:${this.config.zonePassword}`;
    const browser = await chromium.connectOverCDP(`wss://${auth}@brd.superproxy.io:9222`);
    try {
      const page = await browser.newPage();
      await page.goto(url, { waitUntil: 'domcontentloaded', timeout: 60000 });
      return await extract(page);
    } finally {
      await browser.close();
    }
  }

  // Web Scraper API — async bulk collection
  async triggerCollection(datasetId: string, inputs: any[]) {
    const response = await fetch(
      `https://api.brightdata.com/datasets/v3/trigger?dataset_id=${datasetId}&format=json`,
      {
        method: 'POST',
        headers: { 'Authorization': `Bearer ${this.apiToken}`, 'Content-Type': 'application/json' },
        body: JSON.stringify(inputs),
      }
    );
    return response.json();
  }
}

// src/pipeline/scheduler.ts
import cron from 'node-cron';

interface ScrapeJob {
  name: string;
  urls: string[];
  product: 'web_unlocker' | 'scraping_browser' | 'datasets_api';
  schedule: string; // cron expression
  parser: (html: string) => any;
}

export function startScheduler(jobs: ScrapeJob[], client: BrightDataClient) {
  for (const job of jobs) {
    cron.schedule(job.schedule, async () => {
      console.log(`Running job: ${job.name}`);
      if (job.product === 'datasets_api') {
        await client.triggerCollection('dataset_id', job.urls.map(url => ({ url })));
      } else {
        for (const url of job.urls) {
          const html = await client.scrape(url);
          const data = job.parser(html);
          await saveToDatabase(job.name, data);
        }
      }
    });
  }
}

Scenario	Product	Why
Simple HTML pages	Web Unlocker	Cheapest, fastest
JavaScript SPA	Scraping Browser	Needs browser rendering
Search results	SERP API	Pre-parsed JSON output
1000+ URLs one-time	Web Scraper API	Async, handles parallelism
Amazon/LinkedIn/etc.	Pre-built Datasets	No code needed
Login-required pages	Scraping Browser + sticky session	Session persistence

Issue	Cause	Solution
Mixed product confusion	Wrong zone for task	Use decision matrix above
Circular dependencies	Tight coupling	Keep scraper layer separate from proxy layer
Test pollution	Shared mocks	Use dependency injection
Config mismatch	Wrong environment	Load zone config from `zones.json`
