Convert Emails and Outlook Messages to PDF using Node.js

You can easily convert your emails and Outlook messages to PDF documents using Node.js on the cloud. Conversion of emails and Outlook messages to PDF enables you to keep records or share important emails and attachments in a portable form. As a Node.js developer, you can convert EML and MSG files to PDF documents programmatically. In this article, you will learn how to convert EML and MSG files to PDF documents using a REST API in Node.js.

The following topics shall be covered in this article:

EML to PDF Conversion REST API and Node.js SDK

For converting EML and MSG files to PDF, I will be using the Node.js SDK of GroupDocs.Conversion Cloud API. It is a platform-independent document and image conversion solution. It allows you to seamlessly convert your documents and images of any supported file format to any format you need. You can easily convert between over 50 types of documents and images such as Word, PowerPoint, Excel, PDF, HTML, CAD, raster images, etc. It also provides .NET, Java, PHP, Ruby, Android, and Python SDKs as its document conversion family members for the Cloud API.

You can install GroupDocs.Conversion Cloud to your Node.js project using the following command in the console:

npm install groupdocs-conversion-cloud

Please get your Client ID and Client Secret from the dashboard before you start following the steps and available code examples. Once you have your ID and secret, please add in the code as shown below:

global.clientId = "112f0f38-9dae-42d5-b4fc-cc84ae644972";
global.clientSecret = "16ad3fe0bdc39c910f57d2fd48a5d618";
global.myStorage = "";
const config = new groupdocs_conversion_cloud.Configuration(clientId, clientSecret);
config.apiBaseUrl = "https://api.groupdocs.cloud";

Convert EML to PDF using a REST API in Node.js

You can convert your emails to PDF documents programmatically on the cloud by following the simple steps given below:

  1. Upload the EML file to the cloud
  2. Convert EML to PDF using Node.js
  3. Download the converted PDF file

Upload the EML File

Firstly, upload the EML file to the cloud using the following code sample:

// open file in IOStream from local/disc.
var resourcesFolder = 'C:\\Files\\sample.eml';
// read file
fs.readFile(resourcesFolder, (err, fileStream) => {
// construct FileApi
var fileApi = groupdocs_conversion_cloud.FileApi.fromConfig(config);
// create upload file request
var request = new groupdocs_conversion_cloud.UploadFileRequest("sample.eml", fileStream, myStorage);
// upload file
fileApi.uploadFile(request);
});

As a result, the uploaded EML file will be available in the files section of your dashboard on the cloud.

Convert EML to PDF using Node.js

You can easily convert emails from EML files to PDF documents programmatically by following the steps mentioned below:

  • Create an instance of the ConvertApi
  • Create an instance of the ConvertSettings
  • Set the EML file path
  • Assign “pdf” to the format
  • Create an instance of the EmlLoadOptions
  • Set various properties such as displayHeader, displayEmailAddress, etc.
  • Assign EmlLoadOptions to ConvertSettings
  • Create an instance of the PdfConvertOptions
  • Set various properties such as centerWindow, MarginTop, MarginLeft, etc.
  • Assign PdfConvertOptions to ConvertSettings
  • Provide the output file path
  • Create ConvertDocumentRequest with ConvertSettings
  • Convert by calling the convertDocument() method with ConvertDocumentRequest

The following code example shows how to convert an EML file to a PDF document using a REST API in Node.js.

// initialize convert api
let convertApi = groupdocs_conversion_cloud.ConvertApi.fromKeys(clientId, clientSecret);
// define convert settings
var settings = new groupdocs_conversion_cloud.ConvertSettings();
settings.storageName = myStorage;
settings.filePath = "sample.eml"; // input file
settings.format = "pdf"; // output format
// define eml load options
var loadOptions = new groupdocs_conversion_cloud.EmlLoadOptions();
loadOptions.displayHeader = true; // display email header
loadOptions.displayFromEmailAddress = true; // display "from" email address
loadOptions.displayToEmailAddress = true; // display "to" email address
loadOptions.displayEmailAddress = true; // display email address
loadOptions.displayCcEmailAddress = true; // display "cc" email address
loadOptions.displayBccEmailAddress = true; // display "bcc" email address
settings.loadOptions = loadOptions;
// define pdf convert options
let convertOptions = new groupdocs_conversion_cloud.PdfConvertOptions();
convertOptions.centerWindow = true; // set position of the document's window. Default: false.
convertOptions.marginTop = 50; // top margin
convertOptions.marginLeft = 50; // left margin
settings.convertOptions = convertOptions;
settings.outputPath = "output.pdf";
// create convert document request
var request = new groupdocs_conversion_cloud.ConvertDocumentRequest(settings);
// convert document
convertApi.convertDocument(request);
console.log("Document converted successfully: " + response[0].url);
