Arika Mail

@arikajs/mail is the email delivery system for the ArikaJS framework.

It provides a driver-based, configurable mailer with support for templated emails, attachments, and queue-ready delivery — with a beautiful, expressive API but built natively for Node.js and TypeScript.

This package allows applications to send emails without coupling to a specific transport.

✨ Features

• Multiple mailers: Configure different mail transports (SMTP)
• Driver-based transport system: Pluggable email backends
• Class-based Mailables: Reusable email classes
• Templated emails: Using @arikajs/view for rendering
• Attachments: Via @arikajs/storage integration
• Multiple Recipients: Full support for to, cc, and bcc
• Queue-ready: Native async delivery via @arikajs/queue
• Plain text & HTML emails: Support for both formats
• TypeScript-first: Full type safety with JavaScript support

📦 Installation

npm install @arikajs/mail
# or
yarn add @arikajs/mail
# or
pnpm add @arikajs/mail

🚀 Quick Start

Sending a Basic Email

import { Mail } from '@arikajs/mail';

await Mail.to('[email protected]')
  .subject('Welcome')
  .text('Welcome to ArikaJS!')
  .send();

📬 Using Email Templates

await Mail.to('[email protected]')
  .subject('Welcome')
  .view('emails.welcome', { user })
  .send();

Templates are rendered using @arikajs/view.

✉️ Mailables (Recommended)

Mailables provide a clean, reusable way to define emails.

import { Mailable } from '@arikajs/mail';

export class WelcomeMail extends Mailable {
  constructor(private user: any) {
    super();
  }

  build() {
    return this
      .subject('Welcome to ArikaJS')
      .view('emails.welcome', { user: this.user });
  }
}

Sending a mailable:

await Mail.to(user.email).send(new WelcomeMail(user));

Queuing a mailable:

await Mail.to(user.email).queue(new WelcomeMail(user));

Attachments

Attach files using Arika Storage:

await Mail.to('[email protected]')
  .subject('Invoice')
  .attach('invoices/2024.pdf')
  .send();

From raw data (Buffer):

const buffer = await generatePdf(data);

await Mail.to('[email protected]')
  .attachData(buffer, 'invoice.pdf')
  .send();

From streams:

const stream = getDynamicReportStream();

await Mail.to('[email protected]')
  .attachStream(stream, 'report.csv')
  .send();

Multiple Recipients

await Mail.to('[email protected]')
  .cc(['[email protected]', '[email protected]'])
  .bcc('[email protected]')
  .subject('Notification')
  .send();

Queued Delivery

Arika Mail integrates with @arikajs/queue for background processing.

import { Queue } from '@arikajs/queue';

// Configure queue on the mail system
Mail.setQueue(queueManager);

// Dispatch to background
await Mail.to('[email protected]').queue(new WelcomeMail(user));

⚙️ Configuration

Mail configuration is defined via the application config:

export default {
  default: process.env.MAIL_MAILER || 'log',

  mailers: {
    smtp: {
      transport: 'smtp',
      host: process.env.MAIL_HOST || 'smtp.mailtrap.io',
      port: Number(process.env.MAIL_PORT || 587),
      username: process.env.MAIL_USERNAME,
      password: process.env.MAIL_PASSWORD,
      encryption: process.env.MAIL_ENCRYPTION || 'tls',
    },

    log: {
      transport: 'log',
    },

    array: {
      transport: 'array',
    },
  },

  from: {
    address: process.env.MAIL_FROM_ADDRESS || '[email protected]',
    name: process.env.MAIL_FROM_NAME || 'Example',
  },
};

🔌 Extending Mail (Custom Transports)

Create a custom transport:

import { Transport } from '@arikajs/mail';

class CustomTransport implements Transport {
  async send(message: any): Promise<void> {
    // Implementation
  }
}

Register it with MailManager.

🔗 Integration with ArikaJS

@arikajs/mail integrates with:

• @arikajs/view → Email templates
• @arikajs/storage → Attachments
• @arikajs/queue → Async email delivery
• @arikajs/config → Mailer configuration

🧪 Testing

Mailables and transports can be mocked for testing. A log or array transport will be added for test environments.

🛣 Roadmap

• [ ] Queue-based sending
• [ ] Markdown email support
• [ ] Multiple recipients (CC/BCC)
• [ ] Mail previews
• [ ] Retry & failure handling
