Real-time Performance and Accessibility Analysis: The Dev Audit UI provides immediate feedback on website performance and accessibility issues as the code is developed. This proactive approach allows developers to address problems early in the development cycle, preventing costly fixes later on.
Streamlined Workflow: Eliminating the need to switch between development tools, the Dev Audit UI seamlessly integrates into the existing workflow. This eliminates context switching and significantly reduces the time required to identify and resolve issues.
Improved UI Transitions: The revamped UI includes improved rendering transitions, providing a more intuitive and responsive development experience.
Script Re-running Capabilities: Developers can now easily re-run scripts within the audit UI, ensuring that code changes are immediately reflected and analyzed.
Experimental Features: Beyond the core Dev Audit UI improvements, Astro 4.5 introduces several experimental features, including:
Shiki 1.0: A new syntax highlighting library offering improved visual clarity for code.
Multiple CDN Asset Prefixes: This feature allows for more flexible and optimized asset loading strategies.
JSON Schema Datasets: The introduction of JSON Schema datasets enhances the capabilities of the framework for integrating structured data.
New Script Detection Algorithms: These algorithms improve the accuracy and efficiency of the automated performance analysis.
