# @push.rocks/smartmail
a unified format for representing and dealing with mails

## Install

To install `@push.rocks/smartmail`, you'll need Node.js installed on your system. With Node.js installed, run the following command in your terminal:

```bash
npm install @push.rocks/smartmail --save
```

This will add `@push.rocks/smartmail` to your project's dependencies.

## Usage

`@push.rocks/smartmail` provides a unified format for representing and dealing with emails in a Node.js environment. Below, you will find several examples showcasing how to use its main features, including email address validation and creation of mail objects with attachments.

### Importing the Module

First, ensure you're using ESM (ECMAScript Modules) syntax in your TypeScript project. Then, import the necessary classes:

```typescript
import {
  Smartmail,
  EmailAddressValidator
} from '@push.rocks/smartmail';
```

### Validate Email Addresses

You can validate email addresses to check whether they are disposable, belong to a free email provider, or verify their validity in terms of having an MX record.

```typescript
// Instantiate the EmailAddressValidator
const emailValidator = new EmailAddressValidator();

// Validate an email address
const validateEmail = async (email: string) => {
  const validationResult = await emailValidator.validate(email);
  console.log(validationResult);
};

// Example usage
validateEmail('example@gmail.com').then(() => {
  console.log('Email validation completed.');
});
```

### Creating and Using Smartmail Objects

`Smartmail` class allows you to represent an email in a structured way, including attachments, subject, body, and more. Here's how to use it:

```typescript
import { Smartmail } from '@push.rocks/smartmail';
import { Smartfile } from '@push.rocks/smartfile';

// Create a new Smartmail object
const myMail = new Smartmail({
  from: 'no-reply@yourdomain.com',
  subject: 'Welcome to Our Service',
  body: 'Hello {{name}}, welcome to our service!'
});

// Use Smartfile to prepare an attachment (optional)
const attachment = new Smartfile.fromLocalPath('path/to/your/attachment.pdf');
myMail.addAttachment(attachment);

// Accessing and modifying the mail object's properties
console.log(myMail.getSubject({ name: 'John Doe' }));
console.log(myMail.getBody({ name: 'John Doe' }));

// The `getCreationObject` method can be used to retrieve the original creation object
console.log(myMail.getCreationObject());
```

### Email Address Validation Details

The `EmailAddressValidator` class fetches domain information either from a local JSON file or an online source to categorize email domains as disposable, free, or valid based on MX records. Here's a deeper look into validating email addresses and interpreting the results:

```typescript
// Instantiate the validator
const validator = new EmailAddressValidator();

// Validate an email
validator.validate('someone@disposablemail.com').then(result => {
  if (result.valid && !result.disposable) {
    console.log('Email is valid and not disposable.');
  } else {
    console.log('Email is either invalid or disposable.');
  }
  if (result.freemail) {
    console.log('Email belongs to a free mail provider.');
  }
});
```

### Handling Attachments

As shown in the example, attachments can be added to a `Smartmail` object. `Smartfile` (from `@push.rocks/smartfile`) is utilized to handle file operations, allowing you to attach files easily to your email object. Ensure that attachments are in the appropriate format and accessible before adding them to the `Smartmail` object.

### Conclusion

These examples cover the basics of using `@push.rocks/smartmail` for handling emails within your Node.js applications. By leveraging the `Smartmail` and `EmailAddressValidator` classes, you can efficiently represent, validate, and manage email data, enhancing the robustness and functionality of your email-related features.
