Handling Webhooks in Phoenix

I recently had to implement a controller, which took care of receiving and processing webhooks. The thing is, the application had to handle webhooks which often contained very different information, and they were all going to one route and one controller action. This didn't really seem to fit with my goal of keeping controller actions concise and focused. So I set out to find a better solution.

Using ember-freestyle as a component playground

A component playground is an application that you can use to test out and play around with your custom components in isolation from the rest of your project. In the React and Vue ecosystem Storybook is a quite popular project that implements such a component playground as part of your app. In the Ember ecosystem we have the ember-freestyle addon that can be used for this purpose. This blog post will show you how to install ember-freestyle in your app and how to use it to build and test components in isolation.

We recently improved the initial load time of an Ember.js app for mobile clients, by using Ember Engines and leveraging that to lazily loaded parts of the app's code. In this blog post we're going to show how we extracted the engine out of the app and discuss some smaller issues we ran into along the way and how we solved them. So let's dive right in!

Magic Data in Tests

Often when working on large codebases, my changes break some existing tests. While I would prefer my coding to be perfect, it's highly unlikely that I'll ever achieve the state of coding zen, so it's nice to know I have a test suite to catch me when I fall. Given that the codebase is large and in the majority not written by me, I tend to be introduced to code via the test files. One important principle I've started to follow when writing and refactoring tests is AAA.

On Computed Properties vs. Helpers

Ember's computed properties are a great mechanism for encapsulating reactive logic and implementing consistent, auto-updating UIs. Since the past year or so though, there seems to be an increasing tendency in the community to use template helpers as the main tool for expressing this kind of logic right in the templates. Following up on a talk I gave at last year's EmberFest, I'll elaborate in this post why I think that is often not the best choice and what the drawbacks are.
