(JavaScript) Gzip a File

Demonstrates how to create a .gz (gzipped file).

Note

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 requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

var gzip = new CkGzip();

// This will create a .gz such that when ungzipped by a tool such as 7-Zip,
// it will create "qa_data/hamlet.xml".
success = gzip.CompressFile("qa_data/hamlet.xml","qa_output/hamlet.xml.gz");
if (success == false) {
    console.log(gzip.LastErrorText);
    return;
}

// Call CompressFile2 to explicitly specify the ungzip path
// For example, this will create a .gz such that when ungzipped by a tool such as 7-Zip,
// it will create "hamlet.xml".
var embeddedExtractPath = "hamlet.xml";
success = gzip.CompressFile2("qa_data/hamlet.xml",embeddedExtractPath,"qa_output/hamlet2.xml.gz");
if (success == false) {
    console.log(gzip.LastErrorText);
    return;
}

console.log("Success.");
