Let’s learn how to send an email from node.js package,this is supper easy.

So, Let’s Get Started

1.Create a folder in which you want to handle all files .Ex: SEND_MAIL_NODEJS (i am using this folder name ,you can give any name)

2.Open that folder in visual studio code.

3.I hope node.js already installed in your system(windows or Mac),if not here is a good resource How to Install Node.js and NPM on Windows and Mac,please follow.

4.Open terminal in vs and type

• Mac- $ npm init
• Windows - npm init

just hit enter and don’t make any modification in options and in the endtype yes.

It will create a package.json file

5.install Dependencies.

8.Before running the code you need an app password(we need to take this app password from sender email)

9. Go to your google account click on manage your Google account.

10. Click on security option.

11. 2 step verification should be on ,if not then please turn it on first ,then only you will be able to take app password.

After turning on 2 step verification ,you can see this app password option.
