Tests:

compress fflate
// The default compression method is gzip // Increasing mem may increase performance at the cost of memory // The mem ranges from 0 to 12, where 4 is the default fflate.compressSync(buf, { level: 6, mem: 8 });
compress lz-string
LZString.compressToUTF16(string);
compress shorty
shorty.deflate(string)
decompress lz-string
LZString.decompressFromUTF16(lzStringCompressed);
decompress shorty
shorty.inflate(shortyCompressed)
decompress fflate
fflate.decompressSync(fflateCompressed);
