Node.js – Lesson 2: Start server, install dependencies

Next step of creating Node.js application is installing additional frameworks and dependencies that facilitate work with the project.

In our lesson we will use popular web framework “Express” and utility “Nodemon”, that will monitor for any changes in your source and automatically restart your server.

To install this dependencies in console write commands:

npm install express
npm install -D nodemon

Flag -D means that this is developer dependency and it not used in production project.

In section “scripts” write create script “start” and “dev”:

"start": "node index.js",
"dev": "nodemon index.js"
