Installation

Clone the repository

git clone https://github.com/<username>/TS-Walmart-Scraper.git cd TS-Walmart-Scraper

Install dependencies

npm install

Usage

The input for the scraper is a JSON file named INPUT.json, which should be located in the following directory: project_folder\storage\key_value_stores\default\. The INPUT.json file should contain the following fields:

• productUrls: An array of URLs for specific product pages to scrape.
• listingUrls: An array of URLs for category pages or brand pages to scrape (that contains listing of products and pagination).
• keywords: An array of search keywords to use when searching Walmart.com.
• maxPrice: The maximum price for products to scrape.
• minPrice: The minimum price for products to scrape.
• startPageNumber: The page number to start scraping from.
• finalPageNumber: The final page number to scrape.

Using 0 as value for minPrice and maxPrice indicates the scraper to collect products from all price ranges.

Using 0 as value for startPageNumber and finalPageNumber indicates the scraper to crawl all the page range.

To run the scraper, navigate to the project directory in your terminal and run the following command: npm start
