@ahmedayob/email-toolkit

A powerful and flexible toolkit for building, validating, and processing emails with TypeScript. This library offers utilities for handling email headers, attachments, and encoding, making it easier to compose and manage emails programmatically.

Features

• Email Header Management: Easily create and manage email headers.
• Attachment Handling: Add, validate, and format email attachments.
• Encoding Utilities: Encode content in Base64 for attachments.
• Validation: Ensure email content, headers, and attachments are valid with built-in validation schemas.

Installation

To install the toolkit, use npm or yarn:

npm install @ahmedayob/email-toolkit
# or
yarn add @ahmedayob/email-toolkit

Usage

Here's a quick guide on how to use the library:

Email Header

Create and configure email headers:

import { EmailBuilderHeader } from "@ahmedayob/email-toolkit";

const header = new EmailBuilderHeader();
header
  .setFrom("ahmed <[e-mail]>")
  .setTo("ahmed <[e-mail]>")
  .setCc("ahmed <[e-mail]>")
  .setBcc("ahmed <[e-mail]>")
  .setSubject("this is wild duck email test subject")
  .setInReplyTo("[e-mail]")
  .setMIMEVersion("1.0")
  .setContentTransferEncoding("quoted-printable")
  .setContentType("text/html")
  .setCharset("utf8");

Email Attachment

Add attachments to your email:

import { EmailBuilderAttachment } from "@ahmedayob/email-toolkit";
import { Base64 } from "@ahmedayob/email-toolkit";

const attachment = new EmailBuilderAttachment();
attachment.addAttachment({
  headers: {
    "Content-Type": 'text/plain; charset="utf-8"',
    "Content-Transfer-Encoding": "base64",
    "Content-Disposition": 'attachment; filename="test.txt"',
  },
  size: 1234,
  filename: "test.txt",
  mimeType: "text/plain",
  attachmentId: "1234",
  attachmentContent: Base64.encodeToBase64("test"),
});

Building the Email

Combine headers and attachments to create the final email:

import { EmailBuilder } from "@ahmedayob/email-toolkit";

const email = new EmailBuilder();
email.messagebody = "this is message body";

const finalEmail = email.getRawMessage(header.headers, attachment.attachments);
console.log(finalEmail);
