I cannot use localhost:3000

I downloaded the project files and extracted all. I downloaded npm and nodemon and I did all the tests and they are installed. I created the hello.js and tested it in powershell and it worked and confirmed node was installed. I also downloaded WAMP. I restarted my computer and now I still cannot access localhost:3000......

whenever I go to the terminal in VS in the files I downloaded and type nodemon it does not "start" anything it says :

C:\Users\bri15_000\Downloads\javascript_understanding_express_middleware>nodemon Usage: nodemon [nodemon options] [script.js] [args]

See "nodemon --help" for more.

... I tried typing nodemon in command prompt and power shell as well...

please help

Inside Terminal or CMD

  • cd to the location where you have package.json file located
  • then type npm install
  • and then just type npm start and later post the result of error if any
