(JavaScript) Create Zip in a BinData Object

Recursively appends files in a directory tree and writes a zip archive into a Chilkat BinData object.

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

var zip = new CkZip();

// Initialize the zip object.  Because we will never actually write a zip file to the filesystem,
// the filepath passed to NewZip does not matter.
success = zip.NewZip("x.zip");
if (success !== true) {
    console.log(zip.LastErrorText);
    return;
}

// Append a directory tree.  The call to AppendFiles does
// not read the file contents or append them to the zip
// object in memory.  It simply appends references
// to the files so that when WriteBd, WriteZip, or WriteZipAndClose 
// is called, the referenced files are streamed and compressed
// into the .zip output file (or BinData object).

var recurse = true;
success = zip.AppendFiles("c:/temp/a/*",recurse);
if (success !== true) {
    console.log(zip.LastErrorText);
    return;
}

// Write the zip archive into the bdZip object.
var bdZip = new CkBinData();
success = zip.WriteBd(bdZip);
if (success !== true) {
    console.log(zip.LastErrorText);
    return;
}

// We could directly access the bytes of the zip archive, or perhaps
// get the zip bytes in base64 format.
var zipAsBase64 = bdZip.GetEncoded("base64");
console.log(zipAsBase64);

// Or the zip can be used by some other Chilkat method call that accepts
// a BinData object as an argument.
