About once a year or so I create a fresh React project and realize that over the course of the year, everything has changed.
One day you find yourself setting up a new greenfield project. Your team needs a service that connects to an upstream account management system to get the active subscription status of a user. Since it only changes daily, to reduce load, the subscription status will be cached in this service. You now are faced with your first decision. Do you name this customer-subscription-cache? Or do you name it yard-lobster?
One of the first features requested for Shadowmute was a browser extension to simplify the workflow of generating mailboxes. It was also clear very early on that the usage between Chrome and Firefox users was split fairly equally. The documentation for Firefox and Chrome extension development is extremely well written and detailed, so I’m not going to delve too deep into that. What I would like to write about is how to develop for both at the same time.
If you have a kitchen, and that kitchen has drawers, there is a roughly 100% chance you have a junk drawer. You know the one, where you store old phone cables, ribbons, safety pins, expired coupons, and a broken red crayon. The software equivalents of these junk drawers take many forms, commonly named
Utils or the worst offender of all.. the
TestBase. Join me as we take our new found love of dependency injection, and actually put it to good use.
Over the years of my illustrious career, I’ve left several codebases a tattered wreckage. Not intentionally, mind you. Exuberance, eagerness, and a desire to learn new techniques on a slow day all contributed. Half finished implementations of different development techniques littered the landscape. The road to production is paved with good intentions, and a deadline. The code itself worked, shipped, improved but weird vestigial bits floated around. As someone who has fixed as many problems as they have created, you too can larn from my mistaks.
This goes out to all the professional software developers out there working with time constraints just trying to get their job done. Dependency injection (DI) is one of those kinds of concepts that fall through the cracks and becomes assumed knowledge at some point. At a high level it means anything your classes depend on are passed in (usually via a constructor) and it helps make more testable code. Does that make sense? No. not even a little bit. That explanation is terrible.
Comments are a source of contention with many developers. I don’t think that is a shocking or contrarian viewpoint. Generally people have opinions that fall into one of three camps.
In the last post, we added a user interface with React and CoffeeScript to have something other than raw API endpoints to interact with. In this post we will take a look Cross-Site Request Forgery and how it can be mitigated before it becomes a problem.
In the last post, we added another API method to query ticket blocks by respective events while extracting the availability of the tickets in the block. In this post we will take a step back from the back end and give our user interface an overhaul using CoffeeScript-driven React components, replacing our current reliance on server side templates.
In the previous post, we added actors to handle concurrency in a more sensible manner inside of our Play application. In this post we add another API endpoint, relying further on our existing actor model and creating a new method for operating on Futures.
