Features

• Simple and easy to use

Installation

Install the package using npm:

npm install node-otp-sender

Usage

import { nodeOtpSender } from 'node-otp-sender';

const config = {
  senderEmail: '[email protected]',
  senderPassword: 'your-email-password',
  recipientEmail: '[email protected]',
  subject: 'OTP Verification',
  length: 4, // Length of the OTP (default is 4)
  maxRetries: 3, // Number of retry attempts (default is 3)
  retryDelay: 1000 // Delay between retries in milliseconds (default is 1000ms)
};

const sendOtp = async () => {
  try {
    const response = await nodeOtpSender(config);
    console.log(response);
  } catch (error) {
    console.error('Error:', error);
  }
};

sendOtp();

Customizing Retry Behavior

You can customize the retry behavior by adjusting the maxRetries and retryDelay parameters in the configuration object. maxRetries determines the maximum number of retry attempts, and retryDelay sets the delay between retry attempts.

Customizing OTP Length

You can specify the length of the OTP by adjusting the length parameter in the configuration object. The default length is set to 4 digits, but you can change it to any desired length.

Make sure to replace:

• [email protected] with your actual sender email.
• your-email-password with the password of your sender email.
• [email protected] with the recipient's email address.
• OTP Verification with your desired subject.
