The DecompressionStream interface of the Compression Streams API is an API for decompressing a stream of data.

DecompressionStream()

Creates a new DecompressionStream

DecompressionStream.readable

Returns the ReadableStream instance controlled by this object.

DecompressionStream.writable

Returns the WritableStream instance controlled by this object.

In this example a blob is decompressed using gzip compression.

const ds = new DecompressionStream("gzip");
const decompressedStream = blob.stream().pipeThrough(ds);
