(JavaScript) Add Binary Data to a ZIP Using AddBd

See more Zip Examples

This example demonstrates how to use the AddBd method to add binary data from a BinData object as a file entry within a ZIP archive.

The data is created entirely in memory, added to the ZIP as data/binary.dat, and then written to disk.

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;

// Create a new ZIP archive.
var zip = new CkZip();

success = zip.NewZip("inMemoryData.zip");
if (success == false) {
    console.log(zip.LastErrorText);
    return;
}

// Create a BinData object containing binary content.
var bd = new CkBinData();

// Append some bytes as hexadecimal.
// The decoded bytes will become the contents of the ZIP entry.
success = bd.AppendEncoded("000102030405060708090A0B0C0D0E0F","hex");
if (success == false) {
    console.log(bd.LastErrorText);
    return;
}

// Add the BinData contents as a file entry within the ZIP.
// The file will be stored as "data/binary.dat" inside the ZIP archive.
success = zip.AddBd("data/binary.dat",bd);
if (success == false) {
    console.log(zip.LastErrorText);
    return;
}

// Write the ZIP archive to disk and close it.
success = zip.WriteZipAndClose();
if (success == false) {
    console.log(zip.LastErrorText);
    return;
}

console.log("ZIP archive created successfully.");
