In this lecture we will understand how to create a Restful API with NodeJS. We will go through the History and Origins of programming (all the way back to the World War II Enigma and Ana Lovelace's implementation of Charles Babbage Analytical Machine) to the modern day computing. Soon after we will discuss the purpose and the role computers play in our society and understand software development skills and profiles relating this lecture's theme. Then we will see an overview of JavaScript and NodeJS, since its history with Netscape to the modern day usages. We will talk about PaaS, APIs, Rest Architecture, Types of Databases, Frontend Frameworks and Libraries and finally demonstrate one example of a Restful API.

4. NodeJS Overview
JavaScript - Frontend Programming Language.
Server Side Programming Language - Employs scripts on a web server
which produce a customized response for the user's requests.
EcmaScript - ECMAScript is a Standard for a scripting languages.
Frameworks and Libraries - Frontend, Backend, Validation, Routing,
Data/Date manipulation.

5. Hello World

6. JavaScript Reserved Words

7. Static Website

8. Static Website
express.use(__dirname + “/public”)

9. Heroku
Hosting
Cloud
PaaS
Uploading an application:
Heroku create custom-application-name
Git push heroku master

10. API
Application Programming Interface.
JSON / XML
Free APIs: Programmable Web, Comics Vine,
Wikipedia, Meetup, Google, Amazon AWS, IBM Watson.

11. API - Examples

12. API

13. REST
￮ Client/Server
￮ Architectural Style.
￮ Simplicity.
￮ Builds upon existing HTTP’s systems and features.
HTTPs codes:
404 - Not found,
500 - Internal Error,
200 - Everything OK,
401 - Not Authorized.

14. Client/Server Architecture

15. REST

16. Databases
SQL - Structured Query Language
MySQL / SQL Server / PostgreSQL
NoSQL - Not Only SQL
MongoDB / RethinkDB

17. FrontEnd
