Can't make it work locally

[azakordonets]

I tried to run the code with npm start but when i go to http://localhost:8080 I see

The localhost page isn’t working

localhost didn’t send any data.
ERR_EMPTY_RESPONSE

What am i missing ?

I've had this bug with npm before. I'm not sure why it happens but try going to http://127.0.0.1:8080 or changing the port from the default 8080 one.
