The CompressionStream interface of the Compression Streams API is an API for compressing a stream of data.

CompressionStream()

Creates a new CompressionStream

CompressionStream.readable

Returns the ReadableStream instance controlled by this object.

CompressionStream.writable

Returns the WritableStream instance controlled by this object.

In this example a stream is compressed using gzip compression.

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