Compress a String and Save as a Gzip File

See more Gzip Examples

This example demonstrates how to use the CompressStringToFile method to compress a string and write the result directly to a Gzip (.gz) file.

The input string is first converted to its byte representation using the specified character set (in this case, UTF-8). The resulting bytes are then compressed using the Gzip format, and the compressed output is written directly to the specified file.

This method is convenient when you want to generate a compressed file from in-memory text without needing intermediate objects such as BinData or StringBuilder.

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

// This example demonstrates how to compress a string and save the result
// directly to a Gzip (.gz) file.

var gzip = new CkGzip();

// The string to be compressed:
var inputStr = "The quick brown fox jumps over the lazy dog.";

// Compress the string using UTF-8 and write to a file:
success = gzip.CompressStringToFile(inputStr,"utf-8","output.gz");
if (success == false) {
    console.log(gzip.LastErrorText);
    return;
}

console.log("Compression successful.");
console.log("Gzip file written to output.gz");
