A set of reactive controllers that facilitate using the platform observer objects, including:
The modern web platform provides a number of observer helpers that can be used to detect changes to which web applications may want to react. By managing one of these observers with a reactive controller, changes can be easily integrated into the Lit reactive update lifecycle. The controller can also help manage observer cleanup and rendering in response to changes.
From inside your project folder, run:
$ npm install @lit-labs/observers
Here's an example:
import {MutationController} from '@lit-labs/observers/mutation_controller.js';
// ...
class MyElement extends LitElement {
private _observer = new MutationController(this, {
config: {attributes: true},
});
render() {
return html` ${this._observer.value ? `Attributes set!` : ``} `;
}
}
