Goal

Determine the best way to cancel long‑running actions in Moleculer so that resources are freed promptly.

Constraints

Built‑in timeout rejects the promise but leaves the underlying async work alive; AbortController requires the action to listen for AbortSignal and is not part of the stable API. Both approaches work in Node 16+, but older Node versions lack native AbortSignal support.

Open Questions

Should Moleculer expose a standard AbortSignal parameter for actions, making cancellation a supported feature?
If so, how should the broker trigger the signal and how should actions handle cleanup?
Would retaining the current timeout option be sufficient for most use cases, or is a unified cancellation mechanism needed?

Which cancellation strategy for fetch timeouts is most reliable across browsers and Node?

Choosing a consistent fetch timeout cancellation in JavaScript remains unresolved. AbortSignal.timeout is declarative but interacts with manual AbortControllers and risks leaks. Which pattern is reliable across browsers and Node?

Jira Align 8.0 bulk import cancellation leaves partial data without rollback

Jira Align 8.0 bulk import jobs can be cancelled via UI or a cancel flag, but the API lacks a DELETE endpoint and does not roll back partially imported data. The 120‑second hard timeout is not configurable, and the planned partial‑rollback feature remains undecided.

Electron app.whenReady(): Handling Timeouts and Cancellation – Unresolved API Design Decision

How can developers add graceful timeout or cancellation logic to Electron’s <code>app.whenReady()</code> promise, given that the API currently offers no built‑in support? What best practices exist, and is there any roadmap to extend the API?

Does Electron Provide Built‑In Timeout Support for ipc.invoke?

Electron’s promise‑based IPC lacks a timeout argument, leaving developers to wrap calls in <code>Promise.race</code>. An open issue proposes adding a timeout parameter, but no merge has occurred. How can developers gracefully cancel IPC calls and avoid wasted resources?
