## Quick Start 🚀
2020-06-18 22:00:00 +00:00
```typescript
import { MailgunAccount } from '@apiclient.xyz/mailgun';
import { Smartmail } from '@push.rocks/smartmail';
2019-10-23 19:27:42 +02:00
// Initialize your Mailgun account
const mailgun = new MailgunAccount({
apiToken: 'your-mailgun-api-token',
region: 'eu' // or 'us'
});
2019-10-23 19:27:42 +02:00
// Create and send an email
const email = new Smartmail({
from: 'Your App <noreply@yourdomain.com>',
subject: 'Welcome to Our Service! 🎉',
body: '<h1>Hello!</h1><p>Thanks for signing up.</p>'
});
await mailgun.sendSmartMail(email, 'user@example.com');
```
## Core Features
### 📧 Sending Emails
The primary way to send emails is through the `sendSmartMail()` method, which accepts a `Smartmail` object:
```typescript
import { MailgunAccount } from '@apiclient.xyz/mailgun';
import { Smartmail } from '@push.rocks/smartmail';
const mailgun = new MailgunAccount({
apiToken: process.env.MAILGUN_API_TOKEN,
region: 'eu'
});
// Create a rich HTML email
const email = new Smartmail({
from: 'Team <hello@yourdomain.com>',
subject: 'Monthly Newsletter',
body: `
<html>
<body>
<h1>What's New This Month</h1>
<p>Check out our latest updates...</p>
</body>
</html>
`
});
// Send to a recipient
await mailgun.sendSmartMail(email, 'subscriber@example.com');
```
### 📎 Email Attachments
Add attachments seamlessly using the smartmail interface:
```typescript
import { SmartFile } from '@push.rocks/smartfile';
const email = new Smartmail({
from: 'Sales <sales@yourdomain.com>',
subject: 'Your Invoice',
body: '<p>Please find your invoice attached.</p>'
});
// Add attachment from file
const pdfFile = await SmartFile.fromFilePath('./invoice.pdf');
email.addAttachment(pdfFile);
await mailgun.sendSmartMail(email, 'customer@example.com');
```
### 🔄 SMTP Fallback
For edge cases where the Mailgun API has limitations (like empty email bodies), the package automatically falls back to SMTP:
```typescript
// Configure SMTP credentials for fallback
// Format: domain|username|password
await mailgun.addSmtpCredentials(
'yourdomain.com|postmaster@yourdomain.com|your-smtp-password'
);
// This email with empty body will automatically use SMTP
const emptyBodyEmail = new Smartmail({
from: 'System <system@yourdomain.com>',
subject: 'System Notification',
body: ''
});
await mailgun.sendSmartMail(emptyBodyEmail, 'admin@example.com');
// ✅ Automatically sent via SMTP instead of API
```
### 📬 Retrieving Messages
Fetch stored messages from Mailgun's API:
```typescript
// Retrieve by message URL (from Mailgun storage)
const message = await mailgun.retrieveSmartMailFromMessageUrl(
'https://sw.api.mailgun.net/v3/domains/yourdomain.com/messages/...'
);
if (message) {
console.log('Subject:', message.options.subject);
console.log('From:', message.options.from);
console.log('Body:', message.options.body);
// Attachments are automatically fetched
console.log('Attachments:', message.attachments.length);
}
```
### 🔔 Webhook Integration
Process Mailgun webhook notifications:
```typescript
// In your webhook handler
app.post('/webhooks/mailgun', async (req, res) => {
const payload = req.body;
// Retrieve the full message from the webhook payload
const message = await mailgun.retrieveSmartMailFromNotifyPayload(payload);
if (message) {
// Process the received email
console.log('Received email:', message.options.subject);
}
res.status(200).send('OK');
});
```

```typescript

});
```
## Advanced Usage
### Template Variables with Smartmail
Use template variables in your emails:
```typescript
import { Smartmail } from '@push.rocks/smartmail';
const welcomeEmail = new Smartmail({
from: 'Welcome Team <welcome@yourdomain.com>',
subject: 'Welcome {{userName}}!',
body: '<h1>Hi {{userName}}</h1><p>Your account is ready!</p>'
});
// Pass template data
await mailgun.sendSmartMail(
welcomeEmail,
'newuser@example.com',
{ userName: 'John Doe' }
);
```
### Error Handling
```typescript
try {
await mailgun.sendSmartMail(email, 'user@example.com');
console.log('✅ Email sent successfully');
} catch (error) {
console.error('❌ Failed to send email:', error.message);
}
```
### Batch Sending
Send multiple emails efficiently:
```typescript
const recipients = [
'user1@example.com',
'user2@example.com',
'user3@example.com'
];
const email = new Smartmail({
from: 'Newsletter <news@yourdomain.com>',
subject: 'Weekly Update',
body: '<p>Here is your weekly update...</p>'
});
// Send to all recipients
await Promise.all(
recipients.map(recipient =>
mailgun.sendSmartMail(email, recipient)
)
);
```
