React Native Requires Chilkat v11.0.0+

Modify Name of File Stored within Zip when Creating a .zip

See more Zip Examples

Demonstrates how to create a zip where the filename within the .zip is different than the filename that was added from the filesystem. React Native

import { Zip, ZipEntry } from '@chilkat/react-native'

async function chilkatExample() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  const zip = new Zip();

  // Intialize the zip object by calling NewZip.
  zip.newZip('myZip.zip');

  // Add a reference to a file on disk to the zip object.
  // (When appending files to a zip, the files are not actually
  // read into memory.  References to the file(s) are added.
  // When WriteZip is called, the referenced files are streamed in
  // and compressed to the .zip.)
  const saveExtraPath = false;
  try {
    zip.addFile('/temp/a/hamlet.xml', saveExtraPath);
  } catch {
    console.log(zip.lastErrorText);
    return;
  }

  // The zip object references a single file.
  // Retrieve the entry object...
  const entry = new ZipEntry();
  zip.entryAt(0, entry);

  // Set the entry's filename to anything you want:
  entry.fileName = 'somethingElse.xml';

  // Note: Internally, the zip component retains the name of
  // the file referenced.  The current setting of the zip entry's
  // FileName property is stored in the .zip when writing.

  // The zip written here will contain somethingElse.xml
  try {
    await zip.writeZipAndCloseAsync();
    console.log('Zip created!');
  } catch {
    console.log(zip.lastErrorText);
