How to use Email Service of MSG91

Installation

Install the package using npm:

``bash
npm install msg91-service
`

Example 1 (Email service with Template IDs)

`bash
import { EmailServiceFactory, EmailServiceConfig } from 'msg91-service';

// Configuration for Msg91
const msg91Config: EmailServiceConfig = {
serviceType: 'msg91',
config: {
authKey: 'your-msg91-auth-key',
senderId: 'your-sender-id',
domain: 'your-domain.com', // Optional domain parameter
},
};

// Create Msg91 email service instance
const msg91Service = EmailServiceFactory.createService(msg91Config);

// Define the payload to be sent
const msg91Payload = {
email: 'recipient@example.com',
subject: 'Test Subject',
templateId: 'your-template-id',
templateData: {
name: 'John Doe',
orderNumber: '12345',
},
};

// Send email
msg91Service.sendEmail(msg91Payload)
.then(() => {
console.log('Msg91 email sent successfully!');
})
.catch((error) => {
console.error('Error sending Msg91 email:', error);
});
`

Example 2 (Email service with SMTP- nodemailer)

`bash
import { EmailServiceFactory, EmailServiceConfig } from 'msg91-service';

// Configuration for Nodemailer
const nodemailerConfig: EmailServiceConfig = {
serviceType: 'nodemailer',
config: {
smtpHost: "your-smtp-host", // SMTP host address
smtpPort: 587, // SMTP port (usually 587 for TLS)
smtpUser: 'emailer@yourdomain.com', // Your SMTP username
smtpPass: 'your-smtp-password', // Your SMTP password
},
};

// Create Nodemailer email service instance
const nodemailerService = EmailServiceFactory.createService(nodemailerConfig);

// Define the payload to be sent
const nodemailerPayload = {
email: 'recipient@example.com',
subject: 'Test Subject',
htmlData: "

This is a test email from Nodemailer!

// Send email
nodemailerService.sendEmail(nodemailerPayload)
.then(() => {
console.log('Nodemailer email sent successfully!');
})
.catch((error) => {
console.error('Error sending Nodemailer email:', error);
});
