Elixir and Phoenix Screencasts
#62: Simplifying Phoenix Controllers with action_fallback
In this episode we’ll be exploring one method to simplify Phoenix controllers using action_fallback. action_fallback allows you to specify a plug to handle errors in your controller.
#61: Twitter Authentication
In this episode we’ll be adding the ability for users to sign in to a Phoenix web application with Twitter. We’ll use Ueberauth to help us handle the OAuth flow to and from Twitter.
#60: Formatting Numbers
In this episode we’ll use the Number package to help us format numbers for an application. We’ll see how we can convert numbers to different formats like currency, percent, and phone number.
#59: Getting State from a GenServer
In this episode we’ll explore how we can separate the client API of a GenServer from its server callbacks. This can be a good idea to help break GenServer modules up as they become more complex.
#58: Recurring Work with GenServer
In this episode we’ll look at how we can use a GenServer to schedule some recurring work. We’ll create a GenServer fetches the price of a Bitcoin at a regular interval.
#57: Using Plug to Secure Routes
Now that we’ve created our ‘Order History’ pages, we need to make sure only the respective customers are able to view their order history. We’ll use Plug to help us do this.
#56: Completing Order History and Receipt Pages
In this episode we’ll build on the foundation we setup in part 1. We’ll populate our ‘order history’ and ‘receipt’ pages with actual data and make them accessible to our customers.
#55: Defining Routes and Structuring Data
In this episode we get started building an order history page. We’ll look at how our application is structured, how we can fetch data from an API to build our receipts, and how to structure that data.
#54: Detect Security Issues with Sobelow
In this episode we’ll learn how to identify security issues in Phoenix applications. We’ll be using Sobelow to help us identify different potential vulnerabilities.
#53: Parsing HTML with Floki
In this episode we’ll learn how to parse HTML with the Floki package. Floki makes it easy to search for specific nodes in HTML using CSS selectors.
#52: Exploring Phoenix Assigns
Assigns allow you to set and access shared data in different contexts within Phoenix. In this episode we’ll explore how to use assigns in the connection, template, and socket.
#51: Feature Flags
In this episode we’ll learn how we can use feature flags to toggle different features of an application to different users. To do this we’ll be using the FunWithFlags package in an existing Elixir application.
