NestJS Mailer!

NestJS Mailer is a module for NestJS that allows you to send emails using various email providers. It provides a simple and flexible way to send emails from your NestJS application.

Here are some key features of NestJS Mailer:

1. Multiple email providers: NestJS Mailer supports multiple email providers, including:
   • SMTP (e.g., Gmail, Outlook)
   • Sendgrid
   • Mailgun
   • Amazon SES
   • Mailjet
2. Template-based emails: NestJS Mailer allows you to use templates to send emails. You can create templates using Handlebars or EJS, and then use them to send emails.
3. Dynamic email content: You can use dynamic data to populate your email templates. NestJS Mailer supports binding data to templates using Handlebars or EJS.
4. Error handling: NestJS Mailer provides built-in error handling for email sending. You can catch and handle errors using the try-catch block.
5. Async/await support: NestJS Mailer supports async/await syntax for sending emails, making it easy to integrate with your application's async code.

To use NestJS Mailer in your NestJS application, you'll need to:

1. Install the module using npm or yarn: npm install @nestjs/mailer or yarn add @nestjs/mailer
2. Import the module in your NestJS module: import { MailerModule } from '@nestjs/mailer';
3. Configure the email provider in your NestJS module: MailerModule.forRoot({ provider: 'smtp', options: { host: 'smtp.gmail.com', port: 587, secure: false, auth: { user: '[email protected]', pass: 'your-password' } } });
4. Use the MailerService to send emails: @Inject(MailerService) private mailerService: MailerService;

Here's an example of sending an email using NestJS Mailer:

import { Injectable } from '@nestjs/common';
import { MailerService } from '@nestjs/mailer';

@Injectable()
export class EmailService {
  constructor(private readonly mailerService: MailerService) {}

  async sendEmail(to: string, subject: string, template: string, data: any) {
    const message = await this.mailerService.sendMail({
      to,
      subject,
      template,
      context: data,
    });
    console.log(`Email sent to ${to} with subject ${subject}`);
  }
}

In this example, we're using the MailerService to send an email with a template and dynamic data. The sendMail method returns a promise that resolves with the sent email message.

That's it! With NestJS Mailer, you can easily send emails from your NestJS application using various email providers and templates.
