Overview

This small library, known as solid-boundaries, offers a straightforward solution for tracking the size and position of HTML elements. By using reactive primitives, it allows developers to easily tap into the bounds of specific subjects on a web page. This is particularly beneficial for creating interactive elements like tooltips and popovers that rely on real-time updates regarding their dimensions and placement.

The library responds to various events such as scrolling, resizing, and changes in the document, making it a flexible option for dynamic web applications. With its modern approach, it enhances user experience by ensuring that UI elements behave predictably as the layout changes.

Features

Reactive Bounds Tracking: Automatically updates bounds of HTML elements as they change, helping to maintain UI consistency.
Event Response: Reacts to scrolling, resizing of the window, and changes in the document, ensuring accurate positioning at all times.
Integration with ResizeObserver: Leverages the power of the ResizeObserver API for efficient monitoring of element size changes.
MutationObserver Support: Tracks DOM changes that may affect styling, such as class or style attribute modifications.
Easy Setup: Simple installation and usage instructions facilitate quick integration into your project.
Backward Compatibility: Advises using a polyfill for older browsers to maintain functionality and avoid skipped behavior.
Community Contribution: Welcomes contributions from developers, fostering an open-source collaborative environment.
