onMemoryWarning(listener: Function)

import { onMemoryWarning } from '@ray-js/ray';

// Promise usage
try {
  const res = await onMemoryWarning({ ...params });
  console.log(res);
} catch (err) {
  console.log(err.errorMsg);
}

Description

Listen for low-memory warning events. When iOS/Android sends a memory warning to the miniapp process, this event is triggered. Triggering this event does not mean the miniapp is killed; in most cases it is only a warning. Developers can release unnecessary resources upon receiving the notification to avoid further memory pressure.

Parameters

Return Value

None

import { onMemoryWarning } from '@ray-js/ray'

// Listen for low-memory warnings; when the system is low on memory, the callback returns the warning level (level is Android only)
onMemoryWarning(e => {
  console.log("Received memory warning, level:", e.level);
});
// The warning is triggered by the system; keep listening for a while
await new Promise(resolve => setTimeout(resolve, 3000));
