What is the internet?

Programming

A computer will do what you tell it to do.

What is a program?

A program is a set of instructions that you write to tell a computer what to do

What is a programming?

Programming is the task of writing those instructions in a language that the computer can understand.

Simple Circut

True Story

JAVASCRIPT

Variables

Declaration: let age

 

Assignment: age = 25

 

Both at the same time:

let age = 25

Conditional Syntax

if(condition is true) {
  //Do cool stuff
}

Conditional Syntax

if(condition is true) {
  //Do this cool stuff
}else if(condition is true){
  //Do this other cool stuff
}else{
  //Default cool stuff
}

Conditional Syntax

const pizza = "Dominos"

if (pizza === "Papa Johns") {
  console.log("Scram!")
} else if(pizza === "Dominos") {
  console.log("All aboard the train to flavor town")
} else {
  console.log("What are you even doing with your life?")
}

🚨 DANGER 🚨

Assignment vs. Comparison

Multiple Conditions

if (name === "Leon" && status === "Ballin"){
 //Wink at camera
}

Multiple Conditions

if (day === "Saturday" || day === "Sunday"){
  //It is the weekend
}

Functions

  • Functions are simple sets of instructions!

  • Functions are reusable

  • Functions perform one action as a best practice

  • They form the basic "building blocks" of a program

Functions

function name(parameters){
  //body
}

//call
name(arguments)

Functions

function yell(word){
  alert(word)
}


yell("HELLO")

Functions

function yell(word, otherWord){
  alert(word)
  alert(otherWord)
}


yell("HELLO","GOODBYE")

Loops

  • Repeat an action some number of times!

  • Three main types of loops in Javascript

  • For, while, and do while loops

  • Each type offers a different way to determine the start and end points of a loop

Loops - For

for (let i = 1; i < 5; i++) {
  console.log(i)
}

Arrays

  • A data structure to store ordered collections!

  • Array elements are numbered starting with zero

  • Arrays have many methods to manage the order of elements

  • Can be created by a constructor or literal notation

Toasters

Declaring Arrays

let newArr = []

Literal Notation

Declaring Arrays

newArr = ['Zebra',true,21]

Arrays are populated with elements

Elements can be of any type

Array Indexing

Array Indexing

newArr = ['Zebra',,true,21]

console.log( newArr[0] )  //Zebra
console.log( newArr[1] )  //undefined
console.log( newArr[2] )  //true
console.log( newArr[3] )  //21

Elements can be accessed by their index numbers

Array Indexing

newArr = ['Zebra',,true,21]

newArr[1] = 'Bob'

console.log( newArr )  

// ['Zebra','Bob',true,21]

Elements can be updated by using the index at that position

Objects

  • Objects are a collection of variables and functions!

  • Objects represent the attributes and behavior of something used in a program

  • Object variables are called properties and object functions are called methods

  • Objects store "keyed" collections

Think of a physical object

What are it's attributes and behaviors? 

Stopwatch Object

let stopwatch = {}

stopwatch.currentTime = 12

stopwatch.tellTime = function(time){
  console.log(`The current time is ${time}.`)
}

stopwatch.tellTime(stopwatch.currentTime)

Car Factory

Look Ma! New syntax!

class MakeCar{
  constructor(carMake,carModel,carColor,numOfDoors){
    this.make = carMake
    this.model = carModel
    this.color = carColor
    this.doors = numOfDoors
  }
  honk(){
    alert('BEEP BEEP FUCKER')
  }
  lock(){
    alert(`Locked ${this.doors} doors!`)
  }
}

let hondaCivic = new MakeCar('Honda','Civic','Silver', 4)

let teslaRoadster = new MakeCar('Tesla','Roadster', 'Red', 2)

Classes are like templates for objects!

APIs

What are APIs?

APIs

  • A simple interface for some complex action!

  • Think of a restaurant menu! Remember those...

  • Lets one thing communicate with another thing without having to know how things are implemented.

APIs

APIs

Fetch Fido, Fetch!

fetch("https://dog.ceo/api/breeds/image/random")
    .then(res => res.json()) // parse response as JSON
    .then(data => {
      console.log(data)
    })
    .catch(err => {
        console.log(`error ${err}`)
    });

API returns a JSON object that we can use within our apps

Backend!

Butt first!

Javascript is

single-threaded

Synchronous aka processes

one operation at a time

 

vs

If synchronous, how do we do stuff like make an api request and keep scrolling or clicking

Things should block

THE ENVIRONMENT

Not This

THIS

Our JS is running in

a browser

 

Browsers have a BUNCH of APIs we can use that are async and enable us to keeping looking a cute cat photos while those operations are being processed asynchronously

Common browser APIs

 DOM (Document Object Model) API

WAIT
WHAT THE FUCK

Actual words Leon said when figuring all this shit out...

So, yeah, JS can do a lot of "blocking" stuff in the browser because it is handing that stuff off to async

Web APIs

BUT

We are going to need to know how to handle responses coming back from those Web APIs

 

JS does this with callbacks, promises,

and eventually async/await

The Old School Way

Callbacks

You can have a function that takes another function as an argument

aka Higher Order Function

You have seen this a million times

addEventListener('click', callback)

A Callback is the function that has been passed as an argument

Callbacks are not really "a thing" in JS

just a convention 

Callback fires when async task or another function

 is done

function houseOne(){
    setTimeout(() => {
        console.log('Paper delivered to house 1')
        setTimeout(() => {
            console.log('Paper delivered to house 2')
            setTimeout(() => {
                console.log('Paper delivered to house 3')
            }, 3000)
        }, 4000)
    }, 5000)
}
houseOne()

Welcome To Hell

Callback Hell

What if there was a more readable way to handle async code

Promise

An object that MAY have a value in

the future

.then()

A promise object method that runs after the promise "resolves"

 

.then(value)

Whatever value the promise object has gets passed as an argument

 

We've Seen This Before

APIs

Fetch Fido, Fetch!

fetch("https://dog.ceo/api/breeds/image/random")
    .then(res => res.json()) // parse response as JSON
    .then(data => {
      console.log(data)
    })
    .catch(err => {
        console.log(`error ${err}`)
    });

Fetch returns a Promise

Like a bunch of Web APIs running async code

function houseOne(){
    return new Promise((resolve, reject) => {
        setTimeout(() => {
            resolve('Paper delivered to house 1')
        }, 1000)
    })
}
function houseTwo(){
    return new Promise((resolve, reject) => {
        setTimeout(() => {
            resolve('Paper delivered to house 2')
        }, 5000)
    })
}
function houseThree(){
    return new Promise((resolve, reject) => {
        setTimeout(() => {
            resolve('Paper delivered to house 3')
        }, 2000)
    })
}
houseOne()
    .then(data => console.log(data))
    .then(houseTwo)
    .then(data => console.log(data))
    .then(houseThree)
    .then(data => console.log(data))
    .catch(err => console.log(err))

Chaining Don't Read Good

I want my asynchronous code to look sychronous

Async / Await

A way to handle async responses

Promises Under The Hood

Syntactic sugar on top of promises, making asynchronous code easier to write and to read afterwards

Await waits for an async process to complete inside an Async Function

function houseOne(){
    return new Promise((resolve, reject) => {
        setTimeout(() => {
            resolve('Paper delivered to house 1')
        }, 1000)
    })
}
function houseTwo(){
    return new Promise((resolve, reject) => {
        setTimeout(() => {
            resolve('Paper delivered to house 2')
        }, 5000)
    })
}
function houseThree(){
    return new Promise((resolve, reject) => {
        setTimeout(() => {
            resolve('Paper delivered to house 3')
        }, 2000)
    })
}
async function getPaid(){
    const houseOneWait = await houseOne()
    const houseTwoWait = await houseTwo()
    const houseThreeWait = await houseThree()
    console.log(houseOneWait)
    console.log(houseTwoWait)
    console.log(houseThreeWait)
}
getPaid()
async function getPaid(){
    const houseOneWait = await houseOne()
    const houseTwoWait = await houseTwo()
    const houseThreeWait = await houseThree()
    console.log(houseOneWait)
    console.log(houseTwoWait)
    console.log(houseThreeWait)
}
getPaid()

I Need Something Real

APIs

Fetch Fido, Fetch!

async function getACuteDogPhoto(){
    const res = await fetch('https://dog.ceo/api/breeds/image/random')
    const data = await res.json()
    console.log(data)
}
getACuteDogPhoto()

Let's Use A Web API 

setTimeout()

setTimeout and setInterval are not part of the Javascript specification...

 

Most environments include them...

like all browsers and Node.js

function houseOne(){
    console.log('Paper delivered to house 1')
}
function houseTwo(){
    setTimeout(() => console.log('Paper delivered to house 2'), 3000)
}
function houseThree(){
    console.log('Paper delivered to house 3')
}
houseOne()
houseTwo()
houseThree()
function houseOne(){
    console.log('Paper delivered to house 1')
}
function houseTwo(){
    setTimeout(() => console.log('Paper delivered to house 2'), 0)
}
function houseThree(){
    console.log('Paper delivered to house 3')
}
houseOne()
houseTwo()
houseThree()

EVENT LOOP

Time for some data structures

Queue

Like a real queue, the first element which was added to the list, will be the first element out.

This is called a FIFO (First In First Out) structure. 

let queue = []
queue.push(2) // queue is now [2] 
queue.push(5) // queue is now [2, 5] 
let i = queue.shift() // queue is now [5] 
alert(i) // displays 2

Queue Example

Stack

The first pancake made, is the last pancake served.

This is called a stack.

The first element which was added to the list, will be the last one out. This is called a LIFO (Last In First Out) structure. 

let stack = []
stack.push(2) // stack is now [2] 
stack.push(5) // stack is now [2, 5] 
let = stack.pop() // stack is now [2] 
alert(i) // displays 5

Stack Example

JS IS RUNNING IN THE BROWSER

 

V8 Engine
(Parse Code > Runnable Commands)

 

Window Runtime (Hosting Environment)

Gives Us Access To Web APIs

Passes stuff to Libevent (Event Loop)

The Event Loop monitors the Callback Queue and Job Queue and decides what needs to be pushed to the Call Stack.

Backend BABY

Does Javascript have access to the DOM natively (built in)?

Javascript needed Web APIs to handle async and a bunch of stuff in the Browser 

JS is a language that can only do what the hosting environment allows

What Do Servers Need?

Disk Access

(hardrive/ssd)

&&

Network Access

(internet, request / responses)

What if there was a hosting environment that allowed JS to have disk and network access

Music & Light Warning - Next Slide

NODE.js BABY

Node.js is a JavaScript runtime built on Chrome's V8 JavaScript engine.

The same shit that lets you run JS in the browser can now be used to run JS on Servers, Desktops, and elsewhere

True Story

V8 Engine Does All The Heavy Lifting

Engine Vs. Compiler

And just like the browser's Web APIs Node come with a bunch of stuff

Built in Modules

(libraries or collections of functions)

 

HTTP (network access)

FS (file system access)

Access to millions of packages via NPM

(groupings of one or more custom modules)

Not Web APIs, but C/C++ APIs

sorry, don't remember the source

Install Node

Releases?

LTS, Current, Nightly?

Let's Code

Simple Node Server

Just

HTTP & FS

const http = require('http')
const fs = require('fs')
http.createServer((req, res) => {
  fs.readFile('demofile.html', (err, data) => {
    res.writeHead(200, {'Content-Type': 'text/html'})
    res.write(data)
    res.end()
  })
}).listen(8000)

Let's Look

More Complex Backend

How could we clean this up?

Express

Express

Fast, unopinionated, minimalist web framework for Node.js

 

With a myriad of HTTP utility methods and middleware at your disposal, creating a robust API is quick and easy.

But First

Blast To The Past

How Does The Internet Work

"It is a set of rules that allow programs to talk to each other. The developer creates the API on the server and allows the client to talk to it."

CRUD

Create (post) - Make something

Read (get) - Get Something

Update (put) - Change something

Delete (delete) - Remove something

Let's Look At Our App With Authentication

If You Ain't Hip

Live footage of me after adding auth

Authentication? Logged In Users? HOW?

Passport is authentication middleware for Node.js. Extremely flexible and modular, Passport can be unobtrusively dropped in to any Express-based web application.

Passport.js

I'm going to embrace the magic

Live footage of me using passport and AAD

Passport Has Strategies

Each application has unique authentication requirements. Authentication mechanisms, known as strategies, are packaged as individual modules.

It's Really Just Magic

Music & Light Warning - Next Slide

How Do We Stay Signed In?

Express.js uses a cookie to store a session id (with an encryption signature) in the user's browser and then, on subsequent requests, uses the value of that cookie to retrieve session information stored on the server.

 

This server side storage can be a memory store (default) or any other store which implements the required methods

Let's Find The Cookies

Mongoose provides a straight-forward, schema-based solution to model your application data.

Mongoose

Each schema maps to a MongoDB collection and defines the shape of the documents within that collection.

const UserSchema = new mongoose.Schema({
  microsoftId: {

    required: true,
  },
  displayName: {
    type: String,
    required: true,
  }
})

Models are fancy constructors compiled from Schema definitions. An instance of a model is called a document.

Models are responsible for creating and reading documents from the underlying MongoDB database.

mkdir todo-mvc-auth-microsoft
cd todo-mvc-auth-microsoft
npm init 
npm i connect-mongo dotenv ejs

Let's make the nuns proud

app.get('/',(request, response)=>{
    db.collection('rappers').find().toArray()

})

Old API - GET

//Routes File
app.use('/todos', todoRoutes)

//Route to Controller
router.get('/', ensureAuth, todosController.getTodos)

//Controller talking to model
getTodos: async (req,res)=>{
        console.log(req.user)
        try{
            const todoItems = await Todo.find()
            const itemsLeft = await Todo.countDocuments(
              {microsoftId: req.user.microsoftId, completed: false}
            )
            res.render('todos.ejs', 
                       {todos: todoItems, 
                        left: itemsLeft, 
                        user: req.user}
                      )
