Explicit Resource Disposal in Reactive Effect Scopes

Demonstrates Object-Oriented integration between Vue's effectScope and ES2024 Explicit Resource Management (using declaration and Symbol.dispose). This pattern guarantees deterministic unsubscription of reactive side-effects when execution leaves scope boundaries.

javascript

import { effectScope } from 'vue';
 
export class ManagedScope {
  #scope = effectScope();
 
  run(fn) {
    return this.#scope.run(fn);
  }
 
  [Symbol.dispose]() {
    this.#scope.stop();
  }
}
 
using scope = new ManagedScope();
scope.run(() => {
  /* reactive subscriptions */
});

vue

Breakdown

import { effectScope } from 'vue';

Imports Vue's effectScope primitive for grouping recomputations and watchers.

#scope = effectScope();

Enforces hard private encapsulation of the reactive scope using ES private class fields.

[Symbol.dispose]() { this.#scope.stop(); }

Implements the explicit disposable interface, triggering scope teardown automatically.

using scope = new ManagedScope();

Uses the 'using' keyword to bind scope lifetime directly to current block context execution.
