Unzip gzipped file
An example of how to decompress a gzipped file and save it to disk.
Open the gzipped file for reading
const file = await Deno.open("large_file.json.gz");Create a new file to write the decompressed data
const outputPath = await Deno.create("large_file.json");Get the writable stream of the output file
const writableStream = outputPath.writable;Create a decompression stream for gzip format
const stream = new DecompressionStream("gzip");Pipe the readable stream of the gzipped file through the decompression stream and then to the writable stream of the output file
file.readable.pipeThrough(stream).pipeTo(writableStream);Run this example locally using the Deno CLI:
deno run --allow-write --allow-read https://docs.deno.com/examples/scripts/unzip_gzipped_file.ts
