DecompressionStream: DecompressionStream() constructor

Note: This feature is available in Web Workers.

The DecompressionStream() constructor creates a new DecompressionStream object which decompresses a stream of data.

Syntax

new DecompressionStream(format)

One of the following compression formats:

"brotli": Decompress the stream using the Brotli algorithm.
"gzip": Decompress the stream using the GZIP algorithm.
"deflate": Decompress 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": Decompress the stream using the DEFLATE algorithm without a header and trailing checksum.
"zstd": Decompress the stream using the ZSTD algorithm.

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

In this example a gzip-compressed blob is decompressed.

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