• Rendering Ui with Dynamic Data
• Handle User Input

• Listen to Request and Send Responses
• Execute Server-side logic
• Interact with databases and files

An Alternative To PHP, Ruby on Rails, Java etc. is rarely used Standalone!

What is Express?

Express is A node Framework which simplifies writing Server-side code and logic.

• Express.js, offers same functionalities base on node
• Express provide middleware features for request, response through function
• Express provide routing features, view rendering and more.

What is MongoDB?

MongoDB is a NoSQL Database which stores “Documents” in “collections” (instated of “records” in “Tables” as in SQL).

• Its store Application Data like (Users, Products , etc.)
• MongoDB have no Data schema or Relations
• MongoDB easily connect to Node/Express(Not to react)
