Section 16: Beyond The Frontend: Onwards To The Backend!

The goals

💪🏻What is "a Backend"?

✌🏻How The Web Works (Again!)

👍🏻Introducing Backend Programming Languages

 

All the code we wrote thus far influenced what is displayed by the browser and how the loaded website behaves in the browser

For some websites need server-side capabilities as well!

e.g. store data in a database, store uploaded files, load data, send back different HTML content based on data loaded from a database etc...

 

To make this work, we need to remind us agian how the web works

 

 

 

 

How do we write Server-Side Code?

 

we need a programming language is that can be executed on a server (i.e. NOT in the browser)

 

NodeJS is "JavaScript for the server-side"

JavaScript, as you learned it, with more features (e.g. read + write files, parse imcoming requests, send responses, ...)
