A minimal library which polyfills the ResizeObserver API and is entirely based on the latest Specification. It immediately detects when an element resizes and provides accurate sizing information back to the handler. Check out the Example Playground for more information on usage and performance. The latest Resize Observer specification is not yet finalised and is subject to change. Any drastic changes to the specification will bump the major version of this library, as there will likely be breaking changes. Check the release notes for more information.
