API Overview

zip

Compress a file or directory to create a ZIP archive.

Creates a compressed archive from a source file or directory. The archive will include the entire directory structure if the source is a folder.

Platform-specific notes:

• iOS: Password protection is not supported. If a password is provided, it will be ignored and a warning will be logged.
• Android: Supports AES-256 encryption when a password is provided.
• Web: Not supported. Throws an error if called.

import { CapacitorZip } from '@capgo/capacitor-zip';

// Compress a directory without password
await CapacitorZip.zip({
  source: '/path/to/my-folder',
  destination: '/path/to/output.zip'
});

unzip

Extract a ZIP archive to a specified destination directory.

Extracts all files and folders from a ZIP archive while preserving the directory structure. Creates the destination directory if it doesn’t exist.

Platform-specific notes:

• iOS: Supports standard ZIP archives. Password-protected archives are extracted with the provided password.
• Android: Supports AES-encrypted archives with password. Includes zip slip vulnerability protection.
• Web: Downloads each file individually to the browser’s download folder. Cannot create a directory structure.

import { CapacitorZip } from '@capgo/capacitor-zip';

// Extract a standard ZIP archive
await CapacitorZip.unzip({
  source: '/path/to/archive.zip',
  destination: '/path/to/extract-folder'
});

   * Path to the file or directory to compress.

   * This can be an absolute path or a path relative to the app's working directory.
   * If the source is a directory, all its contents will be recursively compressed
   * while preserving the directory structure.
   *
   * Platform-specific notes:
   * - iOS: Use file:// URLs or absolute paths. Relative paths are resolved from the app's documents directory.
   * - Android: Use absolute file paths or content:// URIs for files accessible via the Android Storage Access Framework.
   * - Web: Not supported.
   *
   * @since 7.0.0
   * @example '/Users/app/Documents/my-folder'

   * Path where the ZIP archive will be created.
   *
   * The destination path must include the .zip file extension. If the parent
   * directory doesn't exist, it will be created automatically.

   * Platform-specific notes:
   * - iOS: Use file:// URLs or absolute paths. Relative paths are resolved from the app's documents directory.
   * - Android: Use absolute file paths. The plugin will create any missing parent directories.

   * - iOS: Password protection is NOT supported. The password will be ignored and a warning will be logged.
   * - Android: Supports AES-256 encryption via zip4j library. The password must be provided during extraction.

   * When true (default), the source folder itself becomes the root directory in the archive.

   *
   * This option only applies when the source is a directory. For single files, this option is ignored.
