Compression Streams are now supported on all browsers

The Compression Streams API is for compressing and decompressing streams of data using the gzip or deflate (or deflate-raw) formats.

Using the built-in compression of the Compression Streams API, JavaScript applications do not need to include a compression library, making the download size of the application smaller. This useful API is now supported across all browsers.

Compress data

The following snippet shows how to compress data:

constreadableStream=awaitfetch('lorem.txt').then(
(response)=>response.body
);
constcompressedReadableStream=readableStream.pipeThrough(
newCompressionStream('gzip')
);

Decompress data

To decompress, pipe a compressed stream through the decompression stream.

constdecompressedReadableStream=compressedReadableStream.pipeThrough(
newDecompressionStream('gzip')
);
