            CREATE A FOLDER CALLED controller IN THE src FOLDER
            CREATE A FILE CALLED index.js IN THE controller folder
            ADD THE FOLLOWING CODE
        

This is a simple function to be used with Thunder Client
or Insomnia to test the Server is receiving a request and giving
a response

            Create a file called controllers.js
            and add the following code to it


        

        exports.testGet = (req, res) => {
            res.send("Reply from GET");
        }
        

            NOW RUN npm i nodemon and add this line to package.json
            "dev" : "nodemon src/server.js"
            after the test line called test 
            DON'T FORGET THE COMMA AT THE END OF test OR YOU WILL GET AN ERROR

            You can now test by first running 
            npm run dev
            in the terminal

            If you used PORT 5000 then you should run:
            http://localhost:5000/testGet

            You can choose any port, for example if you
            wanted to use port 3000, run the following:
            export PORT=3000

            Next we will create a model
