Question 1

How does vue-concurrency compare to using async/await with Vue's ref?

Accepted Answer

vue-concurrency adds structured concurrency management and cancellation, which async/await alone lacks. It provides reactive state tracking and strategies like drop() to handle multiple requests, making it more suitable for complex async scenarios like polling or debounced searches.

Question 2

How to implement debouncing with vue-concurrency?

Accepted Answer

Use the drop() or restartable() strategies with a task to implement debouncing. For example, in an autocomplete, wrap the search function in a task with a strategy to control execution frequency, reducing unnecessary API calls as shown in the documentation demos.

Question 3

Does vue-concurrency work with Vue 2 without Composition API?

Accepted Answer

No, for Vue 2, it requires @vue/composition-api. Without it, vue-concurrency is not compatible, as it's built for the Composition API, so legacy Vue 2 projects need this bridge library.

Question 4

What are the bundle size implications of vue-concurrency?

Accepted Answer

The gzipped size is relatively small, but it adds dependencies like CAF. For projects with strict bundle size limits, consider if advanced features like cancellation and concurrency justify the extra KB, as noted in the README's badge.

Question 5

Is vue-concurrency good for handling form submissions?

Accepted Answer

Yes, it's excellent for form submissions due to strategies like restartable(), which can cancel previous submissions and prevent duplicate requests, ensuring data integrity and better user experience.

Question 6

How to cancel a running task in vue-concurrency?

Accepted Answer

Tasks can be cancelled by calling the cancel method on the task instance. For generator-based tasks, cancellation is handled via CAF, and for fetch requests, AbortSignal is integrated, as detailed in the async cancellation feature.

Question 7

vue-concurrency vs Pinia: which is better for async state?

Accepted Answer

vue-concurrency is focused on managing async operations and concurrency, while Pinia is a general state management library. For complex async flows with cancellation and strategies, vue-concurrency is superior, but for simple state storage, Pinia might be enough.
