function asyncQueue<TValue>(fn, initialOptions): (item, position, runOnItemsChange) => boolean

function asyncQueue<TValue>(fn, initialOptions): (item, position, runOnItemsChange) => boolean

Defined in: async-queuer.ts:781

Creates a new AsyncQueuer instance and returns a bound addItem function for adding tasks. The queuer is started automatically and ready to process items.

Error Handling:

• If an onError handler is provided, it will be called with the error and queuer 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 AsyncQueuer instance

State Management:

• Uses TanStack Store for reactive state management
• Use initialState to provide initial state values when creating the async queuer
• Use onSuccess callback to react to successful task execution and implement custom logic
• Use onError callback to react to task execution errors and implement custom error handling
• Use onSettled callback to react to task execution completion (success or error) and implement custom logic
• Use onItemsChange callback to react to items being added or removed from the queue
• Use onExpire callback to react to items expiring and implement custom logic
• Use onReject callback to react to items being rejected when the queue is full
• The state includes error count, expiration count, rejection count, running status, and success/settle counts
• State can be accessed via the underlying AsyncQueuer instance's store.state property
• When using framework adapters (React/Solid), state is accessed from the hook's state property

Example usage:

const enqueue = asyncQueue<string>(async (item) => {
  return item.toUpperCase();
}, {...options});

enqueue('hello');

const enqueue = asyncQueue<string>(async (item) => {
  return item.toUpperCase();
}, {...options});

enqueue('hello');

• TValue

(value) => Promise<any>

AsyncQueuerOptions<TValue>

Function

Adds an item to the queue. If the queue is full, the item is rejected and onReject is called. Items can be inserted based on priority or at the front/back depending on configuration.

TValue

QueuePosition = ...

boolean = true

boolean

queuer.addItem({ value: 'task', priority: 10 });
queuer.addItem('task2', 'front');

queuer.addItem({ value: 'task', priority: 10 });
queuer.addItem('task2', 'front');
