(JavaScript) Create Zip Excluding Files Matching Patterns

How to create a .zip archive excluding (skipping) files that match a set of wildcarded patterns.

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 zip = new CkZip();

success = zip.NewZip("test.zip");
if (success !== true) {
    console.log(zip.LastErrorText);
    return;
}

// Create a string array object with our set of filename patterns
// to be excluded:
var sa = new CkStringArray();
success = sa.Append("*.bak");
success = sa.Append("*.tmp");

// Tell the zip object to use these exclusions:
zip.SetExclusions(sa);

// Append a directory tree.  The 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 WriteZip (or WriteZipAndClose,
// or WriteExe, etc.) is called, the files are compressed
// and encrypted.
var recurse = true;
success = zip.AppendFiles("/temp/a/*",recurse);

success = zip.WriteZipAndClose();
if (success !== true) {
    console.log(zip.LastErrorText);
    return;
}

console.log("Zip Created!");
