MessageKit Nylas is a TypeScript library that provides integration with the Nylas email service, allowing for seamless email sending capabilities within your applications. This package extends the core functionality of MessageKit to support Nylas as an email provider.

Installation

Install the package using pnpm:

pnpm add @messagekit/nylas

Features

• Email Sending: Easily send emails using the Nylas API.
• Attachment Support: Send emails with attachments.
• Requires Core Package: This package requires the @messagekit/core package for functionality.

Usage

Sending an Email

The sendEmail function can be used as follows:

import { sendEmail } from '@messagekit/core';

const emailMessage = {
  from: [{ email: '[email protected]', name: 'Sender Name' }],
  to: [{ email: '[email protected]', name: 'Recipient Name' }],
  subject: 'Hello from MessageKit Nylas',
  text: 'This is a test email sent using MessageKit with Nylas.',
  html: '<p>This is a test email sent using MessageKit with Nylas.</p>',
  attachments: [
    {
      content: 'base64-encoded-content',
      filename: 'attachment.txt',
      path: '/path/to/attachment.txt',
    },
  ],
};

const config = {
  PROVIDER_NAME: 'nylas',
  NYLAS_API_KEY: process.env.NYLAS_API_KEY,
  NYLAS_GRANT_ID: process.env.NYLAS_GRANT_ID,
  NYLAS_API_URL: process.env.NYLAS_API_URL // Optional
};

sendEmail(emailMessage, config)
  .then(response => {
    if (response.success) {
      console.log('Email sent successfully:', response.data);
    } else {
      console.error('Error sending email:', response.messages);
    }
  })
  .catch(error => {
    console.error('Error sending email:', error);
  });

Configuration

Configuration for the sendEmail function can be defined in a .env file. The naming convention for the configuration variables is as follows:

• PROVIDER_NAME: The name of the provider to use.
• NYLAS_API_KEY: The API key for authenticating with the Nylas API.
• NYLAS_GRANT_ID: The Grant ID for authenticating with the connected email account with Nylas API.
• NYLAS_API_URL: An optional custom API URL.

Example .env file:

NYLAS_API_KEY=your_nylas_api_key
NYLAS_GRANT_ID=your_nylas_grant_id
NYLAS_API_URL=https://api.nylas.com

Extensibility

The @messagekit/nylas package is an implementation of the Nylas email provider. The core functionality is provided by the @messagekit/core package, which is designed to be extensible. You can create new email providers by implementing the EmailProviderFactoryInterface and EmailSenderInterface in the core package. This allows you to add support for additional email services in the future.

Rationale

The @messagekit/nylas package is designed to provide integration with the Nylas API for managing email sending workflows in TypeScript applications. By using the core package, developers can easily integrate Nylas capabilities into their domain-driven designs and AI-driven processes.
