With just a few lines of code, Aspose.Email reads all the messages within an MBOX file, extracting key information like the subject, sender, and body. Using the following code sample, you can evaluate the API functionality to access and process emails stored in MBOX format directly in a Node.js environment.

Steps to Read & Save MBOX Messages in Node.js

Before you start, spare a minute to import Aspose.Email to access its MBOX file handling features via npm install aspose.email command. The evaluation version or a temporary license are available for free.

1. Create an instance of MboxrdStorageReader and pass the name of the MBOX file to read.
2. Call readNextMessage() to retrieve the first email message from the MBOX file.
3. Use a while loop to iterate through all messages in the MBOX file:

• Display the subject of each email using console.log.
• Save the email in .eml format using SaveOptions.defaultEml .
• Save the email in .msg format using SaveOptions.defaultMsgUnicode .

4. After processing each message, call readNextMessage() to load the next one.

Code Sample

const ae = require('@aspose/email');

// Create an instance of MboxrdStorageReader and pass the filename
const reader = new ae.Storage.Mbox.MboxrdStorageReader("D:\\Aspose\\Files\\Source Storages\\test.mbox", new ae.Storage.Mbox.MboxLoadOptions);

// Start reading messages
let message = reader.readNextMessage();

// Read all messages in a loop
while (message != null) {
    // Display message details
    console.log("Subject:", message.subject);

    // Save the message in EML or MSG format
    message.save(dataDir + message.subject + ".eml", ae.SaveOptions.defaultEml);
    message.save(dataDir + message.subject + ".msg", ae.SaveOptions.defaultMsgUnicode);

    // Get the next message
    message = reader.readNextMessage();
}
