Zip -- Exclude Files Based on Wildcard Matching

See more Zip Examples

Demonstrates how to use the SetExclusions method to exclude matching files from being added to a .zip. React Native

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

async function chilkatExample() {
  const zip = new Zip();

  zip.newZip('qa_output/x.zip');

  // Let's add files from the directory tree rooted at C:\AAWorkarea\ChilkatSampleProjects

  // However.. we want to exclude all files ending in ".cache" or ".pdb" regardless of the sub-directory.
  // Also exclude all files under any "obj" directory,
  // and we also want to exclude any .exe found under a "win10-x64" directory.

  const saExcludes = new StringArray();
  saExcludes.append('*.cache');
  saExcludes.append('*.pdb');
  saExcludes.append('*/obj/*');
  saExcludes.append('*/win10-x64/*.exe');
  zip.setExclusions(saExcludes);

  // Append promises of paths and files to be zipped.
  const recurse = true;
  try {
    await zip.appendFilesAsync('c:/AAWorkArea/ChilkatSampleProjects/*', recurse);
  } catch {
    console.log(zip.lastErrorText);
    return;
  }

  // Create the zip from the file and directory promises added previously.
  try {
    await zip.writeZipAndCloseAsync();
  } catch {
    console.log(zip.lastErrorText);
    return;
  }

  console.log('Success.');
