Bright Data Local Dev Loop

Overview

Set up a fast, reproducible local development workflow for Bright Data scraping projects with mocked proxy responses, cached results, and vitest integration.

Prerequisites

• Completed brightdata-install-auth setup
• Node.js 18+ with npm/pnpm
• brd-ca.crt SSL certificate downloaded

Instructions

Step 1: Create Project Structure

my-scraper/
├── src/
│   ├── brightdata/
│   │   ├── proxy.ts         # Proxy configuration helper
│   │   ├── scraper.ts       # Scraping functions
│   │   └── cache.ts         # Response caching for dev
│   └── index.ts
├── tests/
│   ├── fixtures/            # Cached HTML responses
│   │   └── example.html
│   └── scraper.test.ts
├── .env.local               # Local credentials (git-ignored)
├── .env.example             # Template for team
├── brd-ca.crt               # Bright Data SSL cert (git-ignored)
└── package.json

Step 2: Build Proxy Configuration Module

// src/brightdata/proxy.ts
import 'dotenv/config';

export interface BrightDataProxy {
  host: string;
  port: number;
  auth: { username: string; password: string };
}

export function getProxy(options?: {
  country?: string;
  city?: string;
  session?: string;
}): BrightDataProxy {
  const { BRIGHTDATA_CUSTOMER_ID, BRIGHTDATA_ZONE, BRIGHTDATA_ZONE_PASSWORD } = process.env;
  if (!BRIGHTDATA_CUSTOMER_ID || ! || !) {
      ();
  }

   username = ;
   (options?.) username += ;
   (options?.) username += ;
   (options?.) username += ;

   {
    : ,
    : ,
    : { username, :  },
  };
}
