Events

onwrite

onwrite: ((start: number, end: number) => unknown) | null;

Called each time data is written to the target. Will be called with the byte range into which data was written.

Use this callback to track the size of the output file as it grows. But be warned, this function is chatty and gets called extremely often.

Methods

on()

on(
	event: K,
	listener: (data: TEvents[K]) => unknown,
	options?: EventListenerOptions,
): () => void;

Registers a listener for the given event.

See EventListenerOptions.

slice()

slice(
	offset: number,
): RangedTarget;

Returns a new RangedTarget that writes data to this target using the given offset.

Useful for writing a file into a section of a larger file.
