Overview

The vue-async-computed plugin is a game-changer for developers working with Vue.js, enabling asynchronous computations in a way that feels intuitive and efficient. Traditional computed properties in Vue handle synchronous operations brilliantly, but when it comes to data that needs to be fetched or processed asynchronously, developers often hit a roadblock. This plugin bridges that gap, allowing Vue components to utilize async functions seamlessly, making data handling smoother and more predictable.

With vue-async-computed, you can now define computed properties that will automatically handle asynchronous data fetching while maintaining all the benefits you expect from regular computed properties. This is especially advantageous when working with external APIs or databases, ensuring that your app remains reactive without compromising on performance.

Features

• Asynchronous Computations: Allows you to define computed properties that can be resolved asynchronously, broadening the scope of what you can achieve with Vue.js.

• Getter-Only Properties: Async computed properties are always getters, providing a consistent API while ignoring any set methods to maintain data integrity.

• Custom Default Values: You can specify a default value for async computed properties, which can be set as a static value or generated via a function based on props or data.

• Dependency Tracking: Just like regular computed properties, async computed properties track dependencies for efficient recalculation, ensuring data integrity without unnecessary computations.

• Watchers for Recalculation: Add additional dependencies to watch for triggering recalculation of async computed properties, providing more control over when updates occur.

• Lazy Evaluation: With the option lazy: true, async computed properties can be computed only when accessed for the first time, reducing unnecessary processing.

• Computation Status Tracking: Each async computed property provides a status object that indicates the current state of the computation, which can be used to inform users of updates or errors in the UI.

• Conditional Updates: Utilize the shouldUpdate mechanism for more controlled recalculations, enabling you to decide when to compute based on specific conditions while retaining access to previous values.
