Hey fellow devs❤! Have you tried sending email from nodemailer npm in NodeJs? Well, hold onto your keyboards because we're about to learn everything from what is smtp to how to set up nodemailer createtransport with nodemailer👊.
What are we waiting for👀? Let's start!
What is SMTP?
Think of SMTP like the postal service for emails! Just as a letter travels from sender to recipient through the postal system, SMTP guides emails from one server to another on the internet. It's like a trusty mail carrier ensuring your message reaches its destination smoothly.
But remember, just as you have to open your mailbox to grab your letters, you'll need another protocol to fetch your emails from the server and read them!
How SMTP Works?
First, your email client says 'Hello' to the server, initiating the email sending process. Then, it packs up your email and sends it off with all its details – like a letter with its destination and contents.
But wait, there's more! The server acts like a Mail Transfer Agent (MTA), checking addresses and routing your email through the internet's postal system. It's like your letter being passed from post office to post office until it reaches its final destination – the recipient's inbox!
So, next time you hit 'send,' remember, your email is on a grand adventure, bouncing from server to server until it lands safely where it belongs!
How Nodemailer and SMTP Connected?
Think of Nodemailer and SMTP as the dynamic duo of email delivery in Node.js!
Nodemailer is like your trusty sidekick, simplifies the process of sending emails from your Node.js apps with its easy-to-use interface. And SMTP?
Well, that's the backbone – the postal system of the internet! Together, Nodemailer and SMTP work hand in hand, easily connecting your app to the vast network of email servers. It's like having your own personal courier service, delivering your messages far and wide with just a few lines of code.
So, next time you hit 'send,' remember, Nodemailer and SMTP have got your back, making sure your emails reach their destination safe and sound! 📮✉️
Install Nodemailer from NPM

Change SMTP Provider
o switch email providers, just tweak the 'host' parameter in the nodemailer.createTransport() method. For instance:
Wrap it in a sendEmail helper function
To simplify email sending across your Node.js application, you can create a handy 'sendEmail' helper function. This function seamlessly connects to the SMTP server using options configured in the 'config.json' file. With this nifty function in place, sending emails from any part of your app becomes a breeze!
Happy Coding✌
