CompressionStream: CompressionStream() constructor

format

One of the following allowed compression formats:

"gzip"

Compresses the stream using the GZIP format.

"deflate"

Compresses the stream using the DEFLATE algorithm in ZLIB Compressed Data Format. The ZLIB format includes a header with information about the compression method and the uncompressed size of the data, and a trailing checksum for verifying the integrity of the data

"deflate-raw"

Compresses the stream using the DEFLATE algorithm without a header and trailing checksum.

TypeError

Thrown if the format passed to the constructor is not supported.

In this example a stream is compressed using gzip compression.

const compressedReadableStream = inputReadableStream.pipeThrough(
  new CompressionStream("gzip"),
);
