Core Learning Goals of Mod 3

  • API Development / Consumption
  • Authentication / Authorization systems
  • Managing deeply-nested data collections
  • Refactoring code into new Design Patterns

Intro to APIs

Everything we build in Mod 3 will focus on the theme of building and consuming APIs.

Work through this tutorial to review an intro to APIs.

Authentication / Authorization

Write up some notes and ideas on the following:

  • you need to store a user in a database table; what do we need to know about them (ie, email, password)
  • how can we store a password in a secure way (ie, if our database is compromised, how can we protect their passwords from prying eyes)
  • how would we store the idea of what a user is allowed to do on a web site
  • how would we build a safe login page
  • how could we tell if a user is logged in since HTTP is “stateless”
  • how could we allow a user to “stay logged in for 7 days” even if your Rails app is restarted

Deeply Nested Collections

When consuming APIs, the data is often returned in deeply nested collections, so you will need to tap into your Mod 1 skills to practice digging through them to retrieve the data you need.

Fork and clone Here Be Dragons. Get the tests to pass.

HTTP Request/Response

  • On one piece of paper, write out all of the parts of an example HTTP GET request (Diagram the DNS look-up as well as how a Rails Application would handle the request via MVC)
  • On a separate piece of paper, write out an example 200 response to that request with all of the parts
  • Bonus write your explanation as a metaphor
  • Bring this to class day 1.

Rails “params” magic.

How does “params” get built in Rails, and what precidence is given for query parameters (ie ?id=5 in a URL) versus dynamic placeholders (ie /book/:id) versus data sent in the body of a request from a form.

Start writing up some notes based on the Rails documentation:

  • https://guides.rubyonrails.org/action_controller_overview.html#parameters

SQL/ActiveRecord

Entering Module 3 with a solid understanding of ActiveRecord and SQL is key to getting the module off to a good start. Make sure you are able to write and understand queries that involve multiple JOIN statements and that combine math functions.

  1. Complete and understand the Intermediate SQL I challenges.
  2. Complete and understand the Intermediate SQL II challenges.

Reading

We will discuss the following on the first day of the inning:

For further exploration

If you have time, here are some activities that will be valuable not only in Mod 3, but in Mod 4 and the job hunt as well.

Data Structures And Algorithms

We are going to be covering various data structures to prepare you for the job hunt and technical interviews. Complete this former M1 project, Jungle Beats

JavaScript/jQuery (What’s this JavaScript I keep hearing about?)

Eloquent JavaScript

JavaScript is the scripting language of web browsers. During Module 3 we’ll start getting our first introductions to JS and we’d like you to work through some basic materials as a preparation.

You are to complete Chapters 1-5 of Eloquent Javascript.

We are mainly looking for you to get experience with the syntax, and at a minimumum you should understand the JS Data Types, Conditionals, and Looping.

jQuery

jQuery is a popular javascript library for manipulating the content of web pages. Dip your toes in with this introductory jQuery tutorial.

Optional Reading on Security topics
