ember-concurrency

What problem does it solve?

Ember apps often struggle with uncoordinated async operations that can cause memory leaks or errors when components unmount mid-flight. ember-concurrency provides structured async primitives to manage tasks with lifecycle awareness (cancellation, cleanup) and to prevent set-on-destroyed-object errors.

Core Features & Use Cases

• Task definitions via task() for structured async logic
• Modifiers: .drop(), .restartable(), .enqueue(), .keepLatest(), and TaskGroups for coordinating multiple tasks
• Utilities: timeout, waitForEvent, didCancel, and cancellation semantics to build robust flows
• Use cases include form saves, data loading, background processing, searches, and polling with deterministic behavior

Quick Start

Create a task with task(async () => { ... }) and invoke it with perform(), using an appropriate modifier to control concurrency.
