Step 1: 🔎 Searching

I found the following snippets in your repository. I will now analyze these snippets and come up with a plan.

Some code snippets I think are relevant in decreasing order of relevance (click to expand). If some file is missing from here, you can mention the path in the ticket description.

Step 2: ⌨️ Coding

[X] Create src/selenium_grid.py ✓ https://github.com/Hardeepex/webscraper/commit/7e760ad71401d97d4064a53608378bb52a535125 Edit
Create src/selenium_grid.py with contents:
• Create a new Python file named selenium_grid.py in the src directory.
• Import the necessary modules at the top of the file. These will include selenium.webdriver and selenium.webdriver.common.desired_capabilities.
• Define a function named setup_selenium_grid that will set up the Selenium Grid. This function will take no arguments and return nothing. It will contain the logic to start the Selenium Grid hub and nodes. This will likely involve subprocess calls to start the Selenium Server standalone jar file with the appropriate arguments for the hub and nodes.
• Define a function named get_webdriver that will get a WebDriver instance connected to the Selenium Grid. This function will take no arguments and return a WebDriver instance. It will create a DesiredCapabilities object with the desired browser and version, and then call webdriver.Remote with the URL of the Selenium Grid hub and the DesiredCapabilities object to get the WebDriver instance.

[X] Modify src/scraping.py ✓ https://github.com/Hardeepex/webscraper/commit/fc1077c8a94d9134ab72b826a15fe5d6475e633f Edit
Modify src/scraping.py with contents:
• Import the get_webdriver function from selenium_grid.py at the top of the file.
• Replace the httpx.get call in the get_html function with a call to get_webdriver to get a WebDriver instance. Use the WebDriver's get method to navigate to the URL.
• Replace the resp.text references with calls to the WebDriver's page_source property to get the HTML source of the page.
• Add a call to the WebDriver's quit method at the end of the get_html function to close the browser once the HTML has been fetched.
