A collection of APIs to provide help with asynchronous tasks like delays, debouncing, deferreds or pooling.

Classes

The MuxAsyncIterator class multiplexes multiple async iterators into a single stream. It currently makes an assumption:

  • The final result (the value returned and not yielded from the iterator) does not matter; if there is any, it is discarded.

Functions

Make Promise or AsyncIterable abortable with the given signal.

Make AsyncIterable abortable with the given signal.

Make Promise abortable with the given signal.

Create a promise which will be rejected with DeadlineError when a given delay is exceeded.

Creates a debounced function that delays the given func by a given wait time in milliseconds. If the method is called again before the timeout expires, the previous call will be aborted.

Creates a Promise with the reject and resolve functions placed as methods on the promise object itself. It allows you to do:

pooledMap transforms values from an (async) iterable into another async iterable. The transforms are done concurrently, with a max concurrency defined by the poolLimit.

Branches the given async iterable into the n branches.

Interfaces

A debounced function that will be delayed by a given wait time in milliseconds. If the method is called again before the timeout expires, the previous call will be aborted.
