Coding & Cookies 2016

Welcome to C&C!

We're happy you're here!

- Introduce yourselves:

  • Standard stuff (name, degree/job, year of study, favourite dessert)
  • What was the first website you ever visited?
  • What is your favourite technology?
  • What did you want to be when you were 10?

Web Developer

I started coding in Front-End and I love everything JavaScript.

Also speak Python, Java, and C :)

 

Fun Fact!

I wanted to be an actress when I was younger.

Checklist!

Do you have...

What makes a website?

files of a basic website

content + additional resources

HTML
CSS
JavaScript

structure

style

interaction

There are no secrets in (front-end) HTML, CSS or JS

THE INTERNET

What people think

THE INTERNET

Reality

Client

Makes requests for information, and takes information from users

Server

Responds with requested information, and stores information from users

Type in 216.58.204.46 - where does it go?

Static

already prepared and served locally

e.g. a simple landing page

Dynamic

generated on the fly and dependent on remote data

e.g. facebook.com

Websites usually come in two flavours...

Both need to be hosted on a web server to be publicly available

Let's get started!

Hyper Text Markup Language

Download this repo:

https://github.com/techsoc/front-end/tree/one

What is a markup language?

Why index.html?

In the old days of the web, navigating a website was a lot more like moving around the folder system on your laptop.

 

You would go to a base site and there would just be a list of the files and folders available: an index.

Try creating an HTML page yourself! :)

<img src="cutecat.jpg" alt="Cute Cat">

<div class="main">

Elements - define semantic value

Opening Tag

Closing Tag

Attribute type

Attribute value

These are HTML Tags

YES

NO

<div> 
    <p>
        <em>I <strong>really</strong> mean that</em>.
    </p>
</div> 
<div> <p> <em>I <strong>really</em> mean</div> that</strong>.</p>

Writing readable code is very important.

So what does this mean?

<!DOCTYPE html>
<html>
    <head>
        <title>Page title</title>
    </head>
    <body>
        ...
    </body>
</html>

Version

Metainformation

Content

CSS

Cascading Style Sheets

- styling language

- simple and easy to use 

- we will cover this in "Making the Web Beautiful"

JavaScript

Programming language

high level, dynamic, prototypal, interpreted

We will cover this in "All about JavaScript"

<link rel="stylesheet" href="/css/master.css">
<script src="js/main.js" type="text/javascript">
body {
  font-family: Arial, sans-serif;
}
console.log("hello!");

What next?

More development concepts

Frameworks, Libraries, APIs

 

These are important building blocks to building robust websites

APIs

Application Programming Interfaces

An abstract description of how to use an application...

  • a set of routines, protocols, and tools for building software applications.
  • specifies how software components should interact
  • used when programming graphical user interface (GUI) components
  • allows you to use code in an already functional application in a stand-alone fashion.

Libraries!

jquery, react, etc

A library is an implementation of an API;

  • a set of functions that a developer can call, usually organised into classes.
  • contains the compiled code that implements the functions and protocols (maintains usage state).

Frameworks!

bootstrap, angular, etc

A web application framework is a type of software framework designed to support development of dynamic websites, web applications, web services and of web resources.

A software framework, in computer programming, is an abstraction in which common code providing generic functionality can be selectively overridden or specialized by user code providing specific functionality.

Frameworks are a special case of software libraries in that they are reusable abstractions of code wrapped in a well-defined Application Program Interface (API), yet they contain some key distinguishing features that separate them from normal libraries.

So...

how do i make dynamic websites and web applications?
