Frontend Masters: AWS for Frontend Engineers

You should have the following completed on your computer before the workshop:

• Install the AWS CLI.
• Have Node.js installed on your system. (Recommended: Use nvm.)
  • Install yarn with brew install yarn.
• Create an AWS account. (This will require a valid credit card.)
• Create a Travis CI account. (This should be as simple as logging in via GitHub).

Chapter 1 - Object Oriented Design

The purpose of design is to allow you to do design later, and it's primary goal is to reduce the cost of change.

SOLID Design:

• Single Responsibility Principle: a class should have only a single responsibility
• Open-Closed Principle: Software entities should be open for extension, but closed for modification (inherit instead of modifying existing classes).
• Liskov Substitution: Objects in a program should be replaceable with instances of their subtypes without altering the correctness of that program.
• Interface Segregation: Many client-specific interfaces are better than one general-purpose interface.

class Dashboard extends Component {
  constructor(props) {
    super(props)
    
    // bind? slows down the initialization path, looks awful
    // when you have 20 of them (I have seen your code, I know)
    // and it increases bundle size
    this.handleStuff = this.handleStuff.bind(this)

    // _this is ugly.

Destructuring(or pattern matching) is a way used to extract data from a data structure(tuple, list, record) that mirros the construction. Compare to other languages, Elm support much less destructuring but let's see what it got !

Tuple

myTuple = ("A", "B", "C")
myNestedTuple = ("A", "B", "C", ("X", "Y", "Z"))

This article has been given a more permanent home on my blog. Also, since it was first written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.

You're Missing the Point of Promises

Promises are a software abstraction that makes working with asynchronous operations much more pleasant. In the most basic definition, your code will move from continuation-passing style:

getTweetsFor("domenic", function (err, results) {
 // the rest of your code goes here.
