我在将Node应用程序部署到Heroku时遇到问题，我在哪里出错？

Question

I keep trying to push my code but hit a brick wall and have a page which gives me an application error and tells me to check the logs.

I am unsure of what to do next.

I can provide the git repo address if that helps.

Thank you !

There are a few things to check for when deployment fails on Heroku.

Have you...

1. Made a procfile on the root folder? It's usually a simple one-line file that tells it to run the server.

    web: node server/server.js 

2. Included necessary modules in your package.json file?

3. Does your server need to connect to a DB? If so, logs should tell you something like database connection failed.

Please refer to the Heroku docs for more info.
