Definition of «headless»

Usage examples

1. Web scraping: Running a headless browser allows you to extract data from websites without the browser's graphical user interface. For example, you can use a headless browser like Puppeteer in JavaScript to scrape information from multiple pages or automate actions like form submissions.
2. Testing: Headless browsers are often used in automated testing to simulate user interactions with a website. By running tests in a headless mode, developers can ensure that their web applications function correctly without the need for a visible browser window.
3. Server-side rendering: Headless browsers can be used to generate server-side rendered HTML for dynamic web applications. This approach is commonly used to improve performance and SEO (Search Engine Optimization) by serving pre-rendered pages to search engine crawlers.
4. Performance monitoring: Headless browsers can be utilized to measure website performance and gather performance-related metrics. By analyzing the loading speed, resource usage, and the time needed to render a page, you can identify bottlenecks and optimize your website accordingly.
5. Automated tasks: Headless browsers can be employed to automate repetitive tasks like form filling, report generation, or data extraction. This significantly reduces manual effort and allows you to programmatically complete tasks that would otherwise require human interaction.
