Edit config/scrapers/*.config.ts files to update:

• Product selectors
• Scraping intervals
• Platform-specific settings

Example Amazon config:

export const AmazonConfig = {
  selectors: {
    productTitle: "span#productTitle",
    price: ".a-price-whole",
    availability: "#availability span",
  },
  scrapingInterval: "6 hours",
};

1. Create a new scraper class extending BaseScraper:

   export class NewStoreScraper extends BaseScraper {
     getProductSelectors() {
       return {
         name: "product-title-selector",
         price: "price-selector",
       };
     }
   
     async scrapeProduct(url: string) {
       // Implementation
     }
   }

2. Register the scraper in the queue system:

   scraperQueue.process("new-store", async (job) => {
     const scraper = new NewStoreScraper();
     return await scraper.scrapeProduct(job.data.url);
   });

docker-compose up -d
