We are always working on new content so Treehouse students can stay up to date with the latest technology. This content roadmap contains everything that's planned for release. Please contact support if there is a course you want to take but don't see listed.
The dates reflected for each course are estimates and may change.
User Authentication with ASP.NET Identity
In this course, you'll learn how to leverage user authentication to secure an application and protect your users' data. You'll update an existing ASP.NET MVC application to use Microsoft's ASP.NET Identity system to implement cookie-based authentication.
Python Basics (Refresh)
Learn the building blocks of the wonderful general purpose programming language Python.
Selenium WebDriver By Example
Manually testing your website can only take you so far. Learn how to use Selenium WebDriver to automate the process for you, and alert you to problems before your users see them.
Build a Weather App (Refresh)
In this course, we will learn about a very common and important element of Android development: downloading data from the Internet! We will request weather forecast data from a free API provided by darksky.net. We will then parse that data (in JSON format) and display it in a single-page app. We will also see how to handle errors and situations when the network is unavailable.
Android Lists and Adapters (Refresh)
A collection of data is often represented in an app in some sort of list. In this course we will learn about the popular Android component called ListView to display and interact with a list of items. We will also learn about RecyclerView, a newer, more efficient version of ListView. We will see how to use some default components as well as building custom lists with our own layouts and adapters.
User Authorization with ASP.NET Identity
In this course, you'll learn how to leverage user authorization to restrict access to part of an application and to control what actions users can and cannot perform. You'll update an existing ASP.NET MVC application to use Microsoft's ASP.NET Identity system to implement authorization using both roles and claims.
Saving Data on a Server
So far all our networking code could do was make GET requests but being able to send and save data to a server is just as important. In this course, let's improve our networking code and learn how to make a POST request. There are a lot of additional concerns when saving data and we'll spend some time talking about security, preventing malicious input and much more.
Unit Testing in iOS
Unit testing allows you to test your application for logic errors, prevent crashes, and even write better code. In this course, we cover the philosophy behind unit testing, ways we can structure our code to make it more testable and look at tools we can use to test our code. We'll look at both tools that come built in, like the XCTest Framework in Xcode, as well as a few third party solutions for both Objective-C and Swift.
Cleaning and Preparing Data
We rely on data to answer important questions, whether we are trying to make the best business decisions or determine the effectiveness of a new medical treatment. But our analyses are only as accurate as the data we are using, and incorrect or “dirty” data can lead to incorrect conclusions and assumptions. Data preparation, also called “cleaning” or “scrubbing”, is an important part of ensuring our analyses are accurate and useful.
UX Design Patterns
Software is often defined by what makes it different, but in many cases, the same UX and design problems appear over and over again; a pattern, across many applications. Rather than come up with a brand new solution for every problem - a solution that could require a tutorial to educate users - it's often best to turn to familiar solutions that a user will immediately recognize. These solutions are called design patterns, and when it comes to UX, these patterns can solve problems in the user interface and they can also help influence the behavior of users.
