Ember AutoResize is an Ember-CLI addon that provides autoresize functionality for Ember components, specifically for `{{input}}` and `{{textarea}}` elements. It automatically adjusts the width and height of these elements to fit their content, with customizable options like `max-width`, `max-height`, `rows`, and `max-rows`. This addon is designed for Ember developers looking to enhance user input experiences by eliminating the need for manual resizing of text fields and text areas.
