Selenium is a popular tool for automating web browsers, allowing you to control and interact with web pages programmatically. In Node.js, you can use the selenium-webdriver package to work with Selenium. Here’s a basic guide on how to get started with Selenium in Node.js:

1. Setup: First, you need to have Node.js installed on your system. You can download it from the official website: https://nodejs.org/

2. Install Dependencies: Open your terminal and create a new Node.js project folder. Navigate to the project folder and run the following command to install the selenium-webdriver package:

   bashCopy code

   npm install selenium-webdriver

3. Import the Package: In your Node.js script file, import the necessary modules from the selenium-webdriver package:

   javascriptCopy code

   const { Builder, By, Key, until } = require('selenium-webdriver');

4. Create a WebDriver Instance: Create a new WebDriver instance to control a specific browser. In this example, let’s use Chrome:

   javascriptCopy code

   async function main() { const driver = await new Builder().forBrowser('chrome').build(); // Your automation code here } main();

5. Interacting with Web Pages: You can use various methods provided by the WebDriver instance to interact with web pages. For example, you can navigate to a URL, find elements, perform actions, and more:

   javascriptCopy code

   async function main() { const driver = await new Builder().forBrowser('chrome').build(); try { await driver.get('https://www.example.com'); const searchInput = await driver.findElement(By.name('q')); await searchInput.sendKeys('Selenium Node.js', Key.RETURN); await driver.wait(until.titleIs('Expected Page Title'), 10000); } finally { await driver.quit(); } } main();

6. Run the Script: Run your Node.js script using the following command:

   bashCopy code

   node your-script.js

Remember that this is just a basic example. Selenium provides a wide range of capabilities for automating browser interactions, such as clicking elements, filling forms, waiting for conditions, handling alerts, and more. Be sure to refer to the official Selenium documentation and the documentation of the selenium-webdriver package for more advanced usage and features.

Please note that browser-specific drivers (e.g., ChromeDriver, GeckoDriver for Firefox) need to be installed and added to your system’s PATH for this to work. You can find these drivers on the respective browser driver download pages.
