Open TGZ Files & Extract Email Data in Node.js

TGZ Reader for Node.js Applications

Aspose.Email for Node.js via .NET is a comprehensive library designed to simplify working with email files and archives, including TGZ. This JavaScript API enables developers to open TGZ files, read their content, and parse critical details within Node.js applications. Designed for easy integration, it supports email data extraction, manipulation, and storage, and is ideal for handling complex TGZ email archives.

The library saves developers countless hours by offering high-performance, ready-to-use functions that eliminate the need to develop custom parsers or data extractors.

Read TGZ Files with Aspose.Email in Node.js

To start coding, please spare a minute to import Aspose.Email to access its TGZ file handling features via npm install aspose.email command. The parsing process involves just a couple of steps:

1. Use TgzReader to open the TGZ file specifying the actual file path.

2. Use the readNextMessage() method in a while loop to iterate through each message. For each message:

• Retrieve the directory name with currentDirectory .
• Access the email message with currentMessage and output the subject with MailMessage.subject .

// Import the Aspose.Email library
const ae = require('@aspose/email');

// Load the TGZ file using TgzReader
let reader = new ae.Storage.Tgz.TgzReader("path/to/ZimbraSample.tgz");

// Loop through each message in the TGZ file
while (reader.readNextMessage()) {
    // Get the current directory of the message
    let directoryName = reader.currentDirectory;
    console.log(directoryName);
    
    // Access the current email message
    let eml = reader.currentMessage;
    console.log(eml.subject);
}

Export Calendar and Contact Items from Zimbra Backup Files

Try the JavaScript code which provides the functionality to extract and organize TGZ file content using Aspose.Email for Node.js via .NET. Zimbra’s calendar and contacts can be exported and saved in iCalendar and VCard formats.

// Import the Aspose.Email library
const ae = require('@aspose/email');

// Initialize TgzReader with the TGZ file
let reader = new ae.Storage.Tgz.TgzReader("test2.tgz");

try {
    // Export contents of the TGZ file to a specified directory
    // Contacts are located in Contacts and Emailed Contacts subfolders
    // Calendar files are found in the Calendar subfolder
    reader.exportTo("out");
} finally {
    // Dispose of the reader after use
    reader.dispose();
}
