About
Justice is an embeddable JavaScript library designed to provide real-time web page performance metrics directly on the page. It creates a lightweight toolbar that displays crucial timing metrics such as pageLoad, domComplete, and domInteractive, along with a streaming FPS meter. A key feature is its budget support, allowing users to set performance thresholds for various metrics; results are color-coded (red for over budget, yellow for near budget, green for under budget) for quick visual assessment. The tool also monitors request counts with budget support, polling for changes as content loads asynchronously. Justice is built with core values of being easily embeddable, having no dependencies, and maintaining a small footprint, aiming to render itself at 60 FPS or greater. It serves as a high-level performance discovery tool, enabling developers and support teams to quickly identify potential performance issues on web pages.
