Gzip Compress In Memory and Base64 Encode

See more Gzip Examples

Demonstrates how to Gzip compress in-memory data and then encode the compressed data to base64. JavaScript

var success = false;

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

var gzip = new CkGzip();

// This example will load a file into the fileData object.
// Your application might load fileData from other sources..
var fileData = new CkBinData();
success = fileData.LoadFile("qa_data/xml/hamlet.xml");
if (success !== true) {
    console.log("Failed to load file.");
    return;
}

// In-place compress the contents of fileData
success = gzip.CompressBd(fileData);
if (success !== true) {
    console.log(gzip.LastErrorText);
    return;
}

// Get the base64 encoded compressed data (in a single line).
var strBase64 = fileData.GetEncoded("base64");
console.log(strBase64);
console.log("--------");

// To get the base64 in multiple lines, as it might appear in MIME,
// use "base64-mime".
var strBase64MultiLine = fileData.GetEncoded("base64-mime");
console.log(strBase64MultiLine);
