When building applications you often come across the case where you need to design a list or search interface for the user. They usually manage lots of data, thus you need a way for the user to show it "in chunks" so that we keep the application performance and the data organized.

In the CSS world, we can see plenty of great preprocessors that improve the language, being SASS/SCSS, LESS and PostCSS the most common among them. SASS seems to be still the most popular and used solution by the date of writing, and that's no surprise since it's fully featured and extends the CSS language with an easy to understand syntax.

This testing series are focused on JavaScript as a language and testing techniques, but since we’re VueSchool, we couldn’t end it up without a simple Vue example, right?
One of the features that amazed me about Jest is snapshot testing. It’s not necessarily a Jest-only feature, but more of a technique and concept. Anyways, the first time I’ve seen it was in Jest.
Test doubles, spies, and mocking, all sound intriguing, but what do they actually mean? Do I really need to spy on my code, or mock it? Let's find out!
In the second part of this 5 part series about testing in JavaScript, we're going to look at a few tools we can use and then write our very first unit tests.
In the very first article in this 5 part series about testing in JavaScript, we're going to look at what testing really is and why we should do it.
So far we’ve build the router in a component and a history module within the source code of our app. The problem of it is that the router is tied to the app, specially because the routes are defined within the AppRouter component.
That could be improved by moving out the routes from the component and passing them as a parameter. But still, the developer must import the AppRouter component and the history.js module and use it around.
Lazy Loading and Code Splitting are two of the main points of the PRPL Pattern, a pattern named by Google which intent is to to provide some structure to make the initial load of a Progressive Web App (PWA) as fast as possible, boosting the performance.
At this point, the router doesn't work as a Single Page App (SPA) router, since it assigns a new route to window.location directly, which performs a hard reload.
