I developed full stack app in react. I deployed my app with heroku, and the front side of the app not working https://jovelapp2.herokuapp.com - message "Cannot get /" https://jovelapp2.herokuapp.com/api/persons - but my backend route works fine when i run the command “node index.js” (the whole app)
I ran the command "npm run build" then i copied the build folder to my backend project, i tested the app locally and ran the command node index.js and everything on my local machine works fine...
This is what i get from the logs :
2022-11-05T20:26:20.838620+00:00 app[web.1]: GET /api/persons {}

Please tell me if you need some piece from my code to understand it better.
Thanks in advance !
It seem your project was deployed successfully.
If you want to handle the GET request in path "/" you need to explicitly create a handler for it.
Looks like Express.js, so something that like this should do the job:
const app = express();
app.get('/', (req, res) => {
res.send('this is the root path!')
});
