Node - how to run app.js?

Question

I am very new to Node.js and I tried to run a project (made by other developer) by having a command in terminal node app.js. But I encountered below error, do you have any idea how to run this project?

I followed few instructions here to run a project.

Error logs below:

Junryls-Mac-mini:app junrylmaraviles$ node app.js

Answer 1

Assuming I have node and npm properly installed on the machine, I would

• Download the code
• Navigate to inside the project folder on terminal, where I would hopefully see a package.json file
• Do an npm install for installing all the project dependencies
• Do an npm install -g nodemon for installing all the project dependencies
• Then npm start OR node app.js OR nodemon app.js to get the app running on local host

Hope this helps someone

use nodemon app.js ( nodemon is a utility that will monitor for any changes in your source and automatically restart your server)
