NodeExpressSetup

Basic Node.js + Express server scaffold.

Setup

1. Install dependencies: npm install
2. Create env file: cp .env.example .env

Run

npm run start

Server starts at http://localhost:3000 by default.

Web Interface

Open http://localhost:3000 in your browser to use the simple email form UI.

Routes

• GET /health -> health check JSON response.
• GET /mail/verify -> verifies Nodemailer SMTP configuration and connectivity.
• GET / -> simple email sending interface.
• POST /send-email -> sends email using JSON body (receiverEmail, subject, body).
• POST /send-email -> sends an email using JSON payload.

SMTP Setup

Set these values in .env:

• SMTP_SERVER
• SMTP_PORT
• EMAIL_USER
• EMAIL_PASS
• RECIEVER_EMAIL

For Gmail, use an App Password (not your normal account password).

Send Email API

      "subject": "Hello",
      "body": "This is from Express + Nodemailer"
