How can I modify the Playwright Text Scraper to scrape multiple pages?

To scrape multiple pages, you can modify the main() function in the playwright_cli_demo.py file. Here's an example:

```python async def main(): async with async_playwright() as p: browser = await p.chromium.launch() page = await browser.new_page()

       urls = ["http://example.com", "http://example.org", "http://example.net"]

       for url in urls:
           await page.goto(url)
           title = await page.title()
           print(f"Title of the page {url}: {title}")

           text_elements = await page.query_selector_all("body >> visible=true")
           print(f"Content of text elements on {url}:")
           for element in text_elements:
               text_content = await element.text_content()
               if text_content:
                   print(text_content.strip())

           print("\n---\n")

       await browser.close()

```

This modification allows the Playwright Text Scraper to iterate through multiple URLs and scrape content from each.

How can I add error handling to the Playwright Text Scraper?

To add error handling, you can use try-except blocks in the main() function. Here's an example:

```python async def main(): async with async_playwright() as p: try: browser = await p.chromium.launch() page = await browser.new_page() await page.goto("http://example.com")

           title = await page.title()
           print(f"Title of the page: {title}")

           text_elements = await page.query_selector_all("body >> visible=true")
           print("Content of text elements on the page:")
           for element in text_elements:
               text_content = await element.text_content()
               if text_content:
                   print(text_content.strip())

       except Exception as e:
           print(f"An error occurred: {str(e)}")

       finally:
           if 'browser' in locals():
               await browser.close()

```

This modification adds error handling to catch and print any exceptions that occur during the scraping process, ensuring that the browser is closed properly even if an error occurs.

Playwright Text Scraper: A CLI app that navigates to http://example.com, retrieves the webpage title, and prints the content of all visible text elements.

Introduction to the Playwright Text Scraper Template

Welcome to the Playwright Text Scraper Template! This template is designed to help you quickly set up a command-line application that navigates to a specified webpage, retrieves the page title, and prints the content of all visible text elements. This is particularly useful for extracting information from websites in an automated fashion. Whether you're looking to scrape data for analysis or monitor changes on a webpage, this template will get you started without the hassle of setting up your development environment or worrying about deployment.

Getting Started with the Template

To begin using this template, simply click on "Start with this Template" on the Lazy platform. This will pre-populate the code in the Lazy Builder interface, so you won't need to copy, paste, or delete any code manually.

Test: Pressing the Test Button

Once you have the template loaded in the Lazy Builder, the next step is to test the application to ensure it's working correctly. Press the "Test" button to deploy the app and launch the Lazy CLI. The application will run automatically, and you will see the output in the CLI interface.

Using the App

After pressing the "Test" button, the Playwright Text Scraper will navigate to "http://example.com" and perform its scraping task. It will print out the title of the page and the content of all visible text elements. There is no frontend interface for this application, as it is designed to be used through the CLI. You can observe the output directly in the Lazy CLI after the application has run.

Integrating the App

If you wish to integrate this Playwright Text Scraper into another service or use it as part of a larger system, you may need to modify the code to navigate to different webpages or handle the scraped data according to your needs. The template provides a solid foundation for web scraping, and you can expand upon it by editing the code within the Lazy Builder interface.

For example, if you want to scrape a different website, you can change the URL in the page.goto("http://example.com") line to the desired webpage. Additionally, if you need to process the scraped data further, you can add your custom logic after the text content is printed.

Remember, all the deployment and execution of the application is handled by Lazy, so you can focus on customizing the code to fit your specific requirements.
