Fixing .variable-env and Home.jsx component

[gbowne1]

• Tested this locally to make sure that the App will now render with no ESLint errors or warnings.

This PR fixes the useEffect in the Home.jsx component so that the app will render. This might need some more cleanup work in the future, but am returning the component to working status anyways.

This PR also fixes the .variable.env file so that it can be more easily used to set up the project.

Edit: this will also fix #143

Hii @gbowne1
Did you have some sample books data ... We can write code on setup.js file to insert in the db Which will be added to db on the initial run of setup.js

@LOGESH-B

That would be a huge task as I have well over 300 books on coding/programming. That would be near impossible by hand. The books I entered on data.json are all valid books. That data could be used. I am not sure that all of them need done for setup, only a few to get the data entry started.

[LOGESH-B]

My sugession is that,
we can have some 10 to 20 books for now,that we can add by default at running of setup file...Instead of showing nothing/(data from data.json file) on initial home page we can render the books from db

[gbowne1]

Yeah, agreed. Well the data I had in data.json are actual books so that could be used.
