Heroku上的MERN应用

Question

I'm trying to get mern app working on heroku. But right now even fixing of node server would be enough.

This is what i have already done.

1. Created app in heroku and push my project to it.
2. Added mLab database link. (running properly on local server)
3. put dev dependencies on the dependencies.
4. Tried running "heroku run node server.js" through heroku CLI. Then it logs as server started on port 8080.

But I cannot access the API or the web interface. My app url = http://travelaround.herokuapp.com

Please note my web application was create using create-react-app My Logs at heroku,

Answer 1

Ok, so from the screenshot of your Heroku dashboard and error, it looks like your dynos are not running. I suggest you compile all of your react code, so you only have static content on your frontend, and then turn on the API dyno, so you can actually curl to it from your react code.
