reset

Reset the IDBDevice instance, clearing all its stored data in the associated IndexedDB.

namespace CheerpX {
  class IDBDevice {
    async reset(): Promise<void>;
  }
}

Parameters

None.

Returns

CheerpX.IDBDevice.reset returns a Promise that resolves once the IDBDevice has been reset. This operation clears all stored data, effectively restoring the IDBDevice to an empty state.

Example

Reset an IDBDevice instance before mounting it.

// Create a read-only block device for a disk image stored on the HTTP server
const blockDevice = await CheerpX.HttpBytesDevice.create("/cheerpXImage.ext2");

// Make the block device read-write using a persistent IndexedDB overlay
const idbDevice = await CheerpX.IDBDevice.create("block_idbDevice");

// Reset the IndexedDB storage
await idbDevice.reset();

const overlayDevice = await CheerpX.OverlayDevice.create(
  blockDevice,
  idbDevice
);
// Initialize the CheerpX environment
const mountPoints = [
  // Use the disk image as the filesystem root
  { type: "ext2", path: "/", dev: overlayDevice },
];
const cx = await CheerpX.Linux.create({
  mounts: mountPoints,
});
