In this article we experiment with implementing the IoC container pattern in Vue.js. The IoC container pattern is prevalent in other languages and frameworks, but not so much in the JavaScript world – we also take a look at why that might be so...
Because of a recent bug hunting session where it took me a couple of hours to drill down several levels of npm dependencies in order to finally find a try...catch statement with the catch part being empty, I decided to write an article about this topic. Although, I have to admit, my first instinct was to be angry at the developer who did this...
I often wonder how to decouple certain parts of an application best. At first, this seems pretty straightforward in the context of Vue.js applications. You have components and components pass down properties and emit events that's it. Right? Yeah, kind of. But also kind of not...
In this article, we explore how we can leverage the power of WebSockets to push content and even component updates to simple Vue.js client applications...
Imagine the following scenario: We have a central content distribution server responsible for pushing new content (think of news articles, for example) to a variety of Vue.js-based client applications. But we not only want to push new content but also describe the shape of the content via Vue.js components...
Today we'll explore how we can use Docker to run our tests in a standardized environment in order to prevent false positives because of differences between operating systems...
Reliable error handling is one of those things which can make the difference between a good application and a great application. In today's article we'll take a look at how we can build renderless components to help us capture errors in our Vue.js applications...
Assuming that we already have integration tests and unit tests in place, it’s time to take a look at how we can build our next line of defense against unwanted regressions in our app. In this article we'll use Jest and Puppeteer to set up Visual Regression Tests...
Reusing logic and keeping your codebase DRY should be one of your top priorities. In a Vue.js application components are the most important means of code reuse. But usually we think of components as a combination of markup, logic and CSS. At first, it might not be very intuitive to use components to provide only logic and not render anything at all...
This is a followup article of my previous article about Integration Testing Vue.js applications with Cypress. In this article, we test the same application but, instead of using Cypress, we want to use the combined forces of Jest and Puppeteer...
