I'm new to react and started learning it recently. Last day I created my 1st app and I was able to see it in the localhost:3000 before taking a break I bookmarked the page and shut down my pc.
Now when I try to access localhost:3000 it show me that it cannot connect. So I tried to use the "npm start" command in visual studio code terminal. But I received several errors and still trying to figure out how to start again the development server.
Any idea how to fix it?

Answer 1

I solved the problem. The fact is that react created inside the project a folder called js inside it there is a package.json that has this small code
{
"dependencies": {
"tar": "^6.1.11"
}
}
when i restarted the visual studio my location in terminal was inside the js folder so when I was trying to run the npm start command it wasn't working.
The fact is that react creates also another folder called my-app inside this one there is another package.json file. So in my case the solution was to move inside the my-app folder using cd. Attention the - symbol how spaces cannot be freely used inside the terminal. So the right way to navigate inside was
cd 'my-app'
if you don't use the quotes it will throw an error. now that I was inside the real app folder I was able to start the server using
npm start
This is a little bit strange and react devs need to add this fact in the documentation. Considering it automatically creates 2 folders and 2 package.json files making it confusing for newbie people like me
