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