Create a project folder and basic setup by doing the following:

mkdir myblog
cd myblog
npm init -y

*** If you didn't pull this code from GitHub ***

Now is the best time to initialize git!

git init
git add .
git commit -m 'init commit'

***

• You should now see package.json as a file in your folder.
• Add two new files - index.js and .env

Now you'll install some npm modules that you'll need for this app:

npm i express dotenv
npm i -D nodemon

express is a framework for building API's and web applications

dotenv loads the .env into system variables - used to keep them secret

nodemon restarts the server when it detects changes in our code files so we don't have to.

• The -D in this command saves this as a dev dependency - it won't be used when the server is eventually deployed

Now for some code!

Add your personal variables to the .env file:
