In this article, I will demonstrate a simple example of sending emails using G-Mail SMTP in Express/ Node.js. fortunately sending emails in express/node js pretty easy, in node.js there are many open source email libraries are available.
In this tutorial we are going to use express-mail library. For sending html emails we are going to use template engine called pugjs, this project was formerly known as Jade.
Create package.json file and keep it in any folder. Put the below code in it.
