# Bright Data SDK Patterns ## Overview Production-ready patterns for Bright Data proxy integrations. Since Bright Data uses HTTP proxy protocols (not a dedicated SDK), these patterns wrap proxy configuration, retry logic, session management, and response parsing into reusable modules. ## Prerequisites - Completed `brightdata-install-auth` setup - Familiarity with async/await and HTTP proxy protocols - axios or node-fetch installed ## Instructions ### Step 1: Proxy Client Singleton ```typescript // src/brightdata/client.ts import axios, { AxiosInstance, AxiosRequestConfig } from 'axios'; import https from 'https'; import 'dotenv/config'; let instance: AxiosInstance | null = null; export function getBrightDataClient(options?: { country?: string; session?: string; zone?: string; }): AxiosInstance { const { BRIGHTDATA_CUSTOMER_ID, BRIGHTDATA_ZONE, BRIGHTDATA_ZONE_PASSWORD } = process.env; const zone = options?.zone || BRIGHTDATA_ZONE!; let username = `brd-customer-${BRIGHTDATA_CUSTOMER_ID}-zone-${zone}`; if (options?.country) username += `-country-${options.country}`; if (options?.session) username += `-session-${options.session}`; if (!instance || options) { instance = axios.create({ proxy: { host: 'brd.superproxy.io', port: 33335, auth: { username, password: BRIGHTDATA_ZONE_PASSWORD! }, }, httpsAgent: new https.Agent({ rejectUnauthorized: false }), timeout: 60000, headers: { 'User-Agent': 'Mo...
