Overview

A Puppeteer-based scraper that logs into Steam, navigates the Community Market for a specified game, and extracts each listing’s internal item_nameid.
These IDs can be used with Steam’s public API to fetch price data, market activity, and more.

---

Features

• Automatic Login
  Authenticate with Steam using stored credentials.
• Configurable Target
  Specify any Steam AppID in settings.json to scrape different games.
• Pagination Handling
  Automatically detect and iterate through all market pages.
• CSV Output
  Appends each record with hash_name in column 1 and item_nameid in column 2 to a CSV file for easy analysis.

---

Prerequisites

• Node.js v14.0.0 or higher
• npm (bundled with Node.js)
• A valid Steam account

---

Installation

1. Clone the repository

   git clone https://github.com/your-username/steam-item-nameid-scraper.git
   cd steam-item-nameid-scraper
   

Configuration

Edit settings.json to set your target game id and file output options ```json { "appId": "730", "outputFolder": "output", "parallelTabs": 10 }

⚠️ WARNING: Increasing parallelTabs speeds things up, but setting the value too high can exhaust Chromium’s memory and crash the browser.

---

Usage

1. First‑time setup (all platforms)

# inside the project folder run
main.bat

A Chrome window launches via Puppeteer so you can log in visually.

Enter your Steam username and password when prompted. They are saved to login_info.json, so future runs skip the prompt unless you delete the file.

If Steam Guard 2‑factor authentication is enabled, approve the sign‑in on your mobile authenticator.
