queue-that

A browser-based queue managed in localStorage for batching and deferring async tasks (e.g., XHR requests) until just before page unload. Current stable version 2.9.0, released as needed on GitHub. It batches tasks into 100ms groups, supports cross-tab coordination (only one active queue per label), exponential backoff on failure, configurable batch size and timeout, and falls back to an in-memory variable if localStorage throws. Distinct from generic queue libraries by its localStorage persistence and unload-safe flushing.
