Dotmsg is a lightweight, versatile JavaScript / TypeScript library for parsing .msg files, specifically designed for both server-side and client-side (browser) applications. Compatible with modern web frameworks, it simplifies the process of extracting email content, metadata, and attachments from Microsoft Outlook .msg files.

npm install dotmsg

• Parse .msg files from Buffer or Uint8Array inputs
• Extract email content, such as plain text and HTML content
• Extract email metadata, such as sender, recipients, subject, and dates
• Extract email attachments

Here's a basic example of how to use the dotmsg library in an node enviroment:

import { DotMsgParser } from "dotmsg";
import fs from "fs";

async function main() {
  const data = fs.readFileSync("path/to/your/file.msg");
  const parser = new DotMsgParser();

  await parser.parseBuffer(data);

  console.log("Subject:", parser.getSubject());
  console.log("Sender:", parser.getSenderEmail());
  console.log("Plain text content:", parser.getTextContent());
}

main();
