Class: TempFileSink

A byte sink that writes data to a temporary file, reducing memory pressure for very large documents. The temp file is automatically deleted on close() or dispose().

Implements

Constructors

Constructor

new TempFileSink(): TempFileSink;

Creates a TempFileSink backed by a temporary file.

Returns

TempFileSink

Accessors

path

Get Signature

get path(): string | null;

Returns the underlying file path once writing has started.

Returns

string | null

Methods

close()

close(): Promise<void>;

Closes the write stream and deletes the temporary file.

Returns

Promise<void>

Implementation of

ByteSink.close


dispose()

dispose(): Promise<void>;

Deletes the temp file without closing the sink cleanly.

Returns

Promise<void>


getBytes()

getBytes(): Promise<Uint8Array<ArrayBufferLike>>;

Reads the temp file contents back into memory. The file must still be open (i.e. close() must not have been called yet).

Returns

Promise<Uint8Array<ArrayBufferLike>>

The full temp file contents as a Uint8Array.


write()

write(chunk): Promise<void>;

Writes a generated PDF byte chunk to the sink.

Parameters

ParameterType
chunkUint8Array

Returns

Promise<void>

Implementation of

ByteSink.write
