What is custom-element-decorators?

Custom Elements are a browser feature that lets you define your own HTML tags, like <user-edit-form>, that behave just like built-in tags. The catch is that building them involves a lot of repetitive setup code: defining attributes, wiring up event listeners, writing templates, and so on. This library cuts through that tedium with decorators, which are special markers you place above your class definition to automatically handle common tasks. Each decorator handles one piece of the boilerplate. @attribute lets you define custom HTML attributes on your element (like "name" or "disabled") and automatically makes them behave like native attributes, so you can set and read them as plain JavaScript properties. @watchAttribute tells the element to react when a specific attribute changes, calling a function you specify. @bindEvent automatically attaches and detaches event listeners when your element is added to or removed from the page. And @rivetsTemplate lets you provide an HTML template string with data binding, so the element's display updates automatically when its data changes. A frontend developer building a reusable component, say, a user profile card or an edit form that gets dropped into multiple pages, would use this to keep the component's code clean and focused on what it actually does rather than on plumbing. Instead of writing dozens of lines to set up attributes and listeners, you add a few decorator lines above your class and move on. The project leans on Rivets JS for its templating, which is a lightweight data-binding library. That's a deliberate choice: it gives you richer templating than raw HTML would, without pulling in a heavy framework. The tradeoff is that your elements become tied to that specific templating approach, rather than being completely framework-agnostic.
