Auto-Open URLs with Node.js – A Beginner-Friendly Script

Want to automate opening a specific URL in your browser multiple times? Whether you're testing link behavior, demoing an app, or running an automation sequence — this simple Node.js script does the job.

🛠️ What This Script Does

• Opens any given URL in Chrome or Edge
• Lets you choose how many times (tabs) you want it to open
• Works from the command line with just one command

📦 Prerequisites

1. Node.js installed on your system
2. Install the open package via terminal:

npm install open

💡 The Node.js Script

Create a file named index.js and paste the code below:

// index.js
const open = require("open").default;

// 🌐 URL to open
const url =
  "https://hiddengemsatlas.blogspot.com/2025/08/auto-open-urls-with-nodejs-beginner.html"; // Replace this with your URL

// ✅ Map browser IDs to app names
const browserMap = {
  1: "chrome",
  2: "msedge",
};

// 🧾 Get command-line arguments
const [, , browserIdArg, countArg] = process.argv;
const browserId = parseInt(browserIdArg);
const count = parseInt(countArg);

// ❌ Validate inputs
if (!browserMap[browserId] || isNaN(count) || count <= 0) {
  console.error("❌ Usage: node index.js <browser_id> <number_of_tabs>");
  console.log("   Browser IDs: 1 - Chrome, 2 - Edge");
  process.exit(1);
}

const selectedBrowser = browserMap[browserId];

(async () => {
  console.log(`🚀 Opening ${url} in ${selectedBrowser}, ${count} time(s)...`);
  for (let i = 0; i < count; i++) {
    console.log(`🧭 Opening tab ${i + 1}`);
    await open(url, { app: { name: selectedBrowser } });
  }
  console.log("✅ All tabs opened.");
})();

🚀 How to Run

Open terminal in your project folder and run:

node index.js 1 3

Explanation:

• 1 = Chrome (use 2 for Edge)
• 3 = Number of tabs to open

📎 Use Cases

• Automatically open your blog or product page
• Simulate link click behavior during UI testing
• Preview marketing links or web apps multiple times
