Is There Any Way to Parse a Folder and Download Files within Using the Electron DownloadItem Class?

When working with Hetzner storage, you might have files stored in a ZIP format, and you need to download and parse these files using Electron. Here, we will explore the processes involved and determine the best approach to achieve your goal.

Hetzner does not provide an API to enumerate or extract specific files directly from a ZIP stored on their storage. Instead, you need to download the entire ZIP file first and then extract and manage the files locally.

Using Electron to Handle ZIP Files

Electron provides an excellent framework for developing cross-platform desktop applications. It allows you to interact with the user's file system, downloading and managing files using methods like `DownloadItem`. However, as we'll see, you cannot directly manipulate ZIP files stored in Hetzner storage without first downloading the ZIP file and then handling it locally.

1. Downloading ZIP Files from Hetzner Storage

First, you need to obtain the download link for your ZIP file from Hetzner storage. Once you have the URL, you can initiate a download using the Electron `DownloadItem` class.

Example:

const downloadItem  await ({ properties: ['saveFile'] });const downloadUrl  '';const downloadItem  (downloadUrl);

2. Extracting ZIP Files Using Electron

Once the ZIP file is downloaded, you can use the `adm-zip-electron` library to extract the contents. This library provides a convenient way to handle ZIP files in Electron applications.

Example:

const AdmZip  require('adm-zip-electron'); // This is a hypothetical module for demonstrationconst zip  new AdmZip('');zip.extractAllTo('path/to/extract/files', true);

3. Enumerating and Extracting Specific Files

Using the `adm-zip-electron` library, you can enumerate the files inside the ZIP and extract specific files based on your requirements. This is particularly useful if you only need to download certain files and not the whole ZIP.

Example:

const Zip  require('adm-zip-electron');const zip  new Zip('');const entries  (); // List of all files and directories in the ZIP// Enumerate the files and extract specific ones(entry > {  if (entry.entryName.endsWith('.txt')) { // Extract only text files    zip.extractEntryTo(entry.entryName, 'path/to/extract', true); // true means overwrite existing files  }});

Conclusion

While Hetzner storage does not provide a direct API to enumerate or extract files from ZIP files, you can achieve your goals by using Electron and third-party libraries like `adm-zip-electron`. This approach allows you to download and manage files more effectively.

By understanding the limitations and leveraging the appropriate tools, you can create a robust and efficient desktop application for managing your files stored on Hetzner storage.

Key Takeaways: Download ZIP files from Hetzner storage using Electron's `DownloadItem` class. Use `adm-zip-electron` to extract and manage ZIP files locally. Enumerate and extract specific files from the ZIP archive as needed.
