Professional Development

Ruby and Rails Versions

Follow this guide to make sure your versions are correct.

Intro to APIs

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

Work through this tutorial to get a brief intro to APIs.

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.

Refactoring Workshop

In Mod 3, we will focus not only on getting code to work but also writing high quality code. This will involve topics covered in mod 1 such as creating classes and methods, adhering to SRP, and general refactoring principles. Review these topics by forking and cloning the refactoring workshop. Work through the activity in the README. This was designed as a partnered activity. You may choose to pair with a classmate or work solo. If working alone, write answers to the questions in your notebook instead of discussing.

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 Routing

Rewrite your Monster Shop routes.rb:

Module 3 requires you to know URLs, paths and HTTP verbs inside and out. Rewrite the routes file for your Monster Shop to use only methods that map directly to HTTP verbs: get, post, put, patch and delete. You will probably need to add to: and as: parameters to make sure your apps continue to work, and tests continue to pass.

If you wrote your routes that way already, replace them using resources.

If you do not own the repo for your project, fork it, and rewrite the routes file individually.

NOTE: This is not because one way is better, but it’s extremely important to understand what every line of your routes file is doing. Rails Engine demands a solid understanding of Rails routing.


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.


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