⚙️ How to Use

Step 1: Add Dependency

• Install EmailParserLib in your module

Step 2: Use the Parser

Input:

• FileName (Text)
• FileBinaryContent (Binary )

Step 3: Call JavaScript

parseEmail(FileName, FileBinaryContent)
  .then(result => {
    $parameters.Output = JSON.stringify(result);
    $resolve();
  })
  .catch(error => {
    console.error(error);
    $reject();
  });

Step 4: Deserialize JSON

• Map output to ParsedEmail structure

Step 5: Render Data

• Use HTML_To_Inject for preview
• Use Attachments for downloads

📄 Output Structure

{
  "Subject": "",
  "From": "",
  "To": "",
  "CC": "",
  "BCC": "",
  "BodyHTML": "",
  "Attachments": [],
  "HTML_To_Inject": ""
}

🔐 Security Considerations

• Always sanitize HTML using DOMPurify
• Avoid rendering raw HTML directly
• Validate file size before parsing
• Restrict attachment types if needed

⚠️ Limitations

• Large files may impact browser performance
• Base64 attachments increase payload size
• .msg parsing depends on third-party reader

💡 Best Practices

• Limit file size (e.g. 10MB)
• Use lazy loading for large attachments
• Render HTML inside controlled container
• Avoid storing raw binary in DB
