Defined in: async-debouncer/createAsyncDebouncer.ts:118

A low-level Solid hook that creates an AsyncDebouncer instance to delay execution of an async function.

This hook is designed to be flexible and state-management agnostic - it simply returns a debouncer instance that you can integrate with any state management solution (createSignal, etc).

Async debouncing ensures that an async function only executes after a specified delay has passed since its last invocation. Each new invocation resets the delay timer. This is useful for handling frequent events like window resizing or input changes where you only want to execute the handler after the events have stopped occurring.

Unlike throttling which allows execution at regular intervals, debouncing prevents any execution until the function stops being called for the specified delay period.

Unlike the non-async Debouncer, this async version supports returning values from the debounced function, making it ideal for API calls and other async operations where you want the result of the maybeExecute call instead of setting the result on a state variable from within the debounced function.

Error Handling:

• If an onError handler is provided, it will be called with the error and debouncer instance
• If throwOnError is true (default when no onError handler is provided), the error will be thrown
• If throwOnError is false (default when onError handler is provided), the error will be swallowed
• Both onError and throwOnError can be used together - the handler will be called before any error is thrown
• The error state can be checked using the underlying AsyncDebouncer instance

The hook uses TanStack Store for reactive state management. The selector parameter allows you to specify which state changes will trigger a re-render, optimizing performance by preventing unnecessary re-renders when irrelevant state changes occur.

By default, there will be no reactive state subscriptions and you must opt-in to state tracking by providing a selector function. This prevents unnecessary re-renders and gives you full control over when your component updates. Only when you provide a selector will the component re-render when the selected state values change.

Available state properties:

• canLeadingExecute: Whether the debouncer can execute on the leading edge
• executionCount: Number of function executions that have been completed
• hasError: Whether the last execution resulted in an error
• isPending: Whether the debouncer is waiting for the timeout to trigger execution
• isExecuting: Whether an async function execution is currently in progress
• lastArgs: The arguments from the most recent call to maybeExecute
• lastError: The error from the most recent failed execution (if any)
• lastResult: The result from the most recent successful execution
• status: Current execution status ('disabled' | 'idle' | 'pending' | 'executing')

• TFn extends AnyAsyncFunction

• TSelected = {}
