What is Live.js?
Live.js is a lightweight JavaScript library designed to enhance web development workflow by providing automatic browser refresh functionality. It monitors changes to HTML, CSS, and JavaScript files in real-time, applying updates dynamically without requiring manual intervention. This tool integrates seamlessly into existing development environments, supporting various browsers and backend technologies.
The tool operates by sending consecutive HEAD requests to the server to detect file modifications. When changes are identified, CSS updates are applied immediately, while HTML or JavaScript modifications trigger a full page reload. This approach ensures developers always view the most current version of their work, streamlining the design and debugging process.
