Gmail Node Mailer Package

This Node.js package simplifies sending emails using the Gmail API. It wraps the complexity of Google's authentication and email sending process into a few easy-to-use functions.

Features

• Easy Gmail API authentication using service accounts.
• Send emails with simple function calls.
• Includes TypeScript definitions for better development experience.

Installation

```bash npm install gmail-node-mailer ```

Or if you prefer using Yarn:

```bash yarn add gmail-node-mailer ```

Quick Start

First, ensure you have a service account set up in your Google Cloud Project and have downloaded the service account JSON file. Also, make sure the Gmail API is enabled.

Setting Up Environment Variables

Create a `.env` file in your project's root directory and add the following variables:

```plaintext GMAIL_USER=your_email@example.com ```

Replace `your_email@example.com` with the email address of the Google account you wish to send emails from. Ensure this account is associated with your Google Cloud Project and has the Gmail API enabled.

Using the Package

1. Initialize the Email Client

   Import and call `initializeClient` at the start of your application. This function initializes the Gmail API client using credentials from your service account JSON file and the sender email from your environment variables.

   ```javascript import { initializeClient } from 'gmail-node-mailer';

   const emailClient = await initializeClient(); ```

2. Send an Email

   Once the client is initialized, you can send emails using the `sendEmail` function.

   ```javascript import { sendEmail } from 'gmail-node-mailer';

   const emailResponse = await sendEmail({ senderEmail: 'your_email@example.com', recipientEmail: 'recipient@example.com', subject: 'Hello World', message: 'This is a test email sent from gmail-node-mailer.' });

   console.log(emailResponse); ```

API Reference
