Starting Node/express project in terminal error

I was working on a MEAN stack tutorial last night, https://thinkster.io/angulartutorial/mean-stack-tutorial/ , and everything was working fine. Then this morning when I try to start it again I keep getting an npm error. It says cannot connect to localhost: 27017, but I was connected to port:3000 last night, and the /bin/www code is set to 3000.

I think the error is maybe in the package.json file: "start": "node ./bin/www" but I am not sure and need help. Thanks.

Darraghs-MacBook-Pro:flapper-news dkdesign$ npm start

> [email protected] start /Users/dkdesign/flapper-news
> node ./bin/www

        throw er; // Unhandled 'error' event

Try running:

To check if it worked:

27017 is the mongodb's default port. Make sure, you have started the mongodb server before running your application.
