core/channel-effects

Call redux-saga's takeEvery(channel, worker) directly with the EventChannel returned by your app-provided channel factory. Wrap the usage in try/finally and call channel.close() in the finally block to release the underlying subscription.

Use takeEvery(channel, worker) when events are independent and each should spawn a concurrent worker. Use takeLatest(channel, worker) when only the latest event matters, such as streaming progress updates or latest search results, so each new event cancels the previous worker.

Leaks happen when hand-rolled while(true) take(channel) loops omit try/finally cleanup, so the channel is never closed on cancellation or error. Replace the loop with takeEvery(channel, worker) inside try/finally and call channel.close() explicitly.

No. For selector-derived state changes, use takeEveryFromSelector or takeLatestFromSelector from @augmentcode/themis/saga, which handle subscription and args-tuple keying automatically. Wrapping a selector in a generic EventChannel discards those guarantees.

No. Native redux-saga watcher effects do not own app-created channel resources. You must keep ownership explicit by wrapping usage in try/finally and closing the channel yourself when the saga finishes or is cancelled.
