Often you need two different sets of navigation stacks for pre and post user authentication. Usually, to see more content, you have to be authenticated in some way. In many Apps, authentication is one of the most important parts because it confirms that the person trying to gain access to protected content has the right to access the information. Learning how to do it right is an important step in building a great, intuitive, and easy to use/navigate the application.

Embracing the fragility of the web empowers us to build UIs capable of adapting to the functionality they can offer, whilst still providing value to users. The User Experience (UX) doesn’t need to be all or nothing — just what is usable. This premise, known as graceful degradation allows a system to continue working when parts of it are dysfunctional — much like an electric bike becomes a regular bike when its battery dies. This article explores how graceful degradation, defensive coding, observability, and a healthy attitude towards failures better equips us before, during, and after an error occurs.

Dialogs are everywhere in modern interface design (for good or for bad), and yet many of them are not accessible to assistive technologies. In this post, Kitty Giraudel is going to write a small JavaScript library for authoring accessible dialogs from the very beginning. The goal is to understand what goes into it. She’s not going to deal with styling too much, just the JavaScript part.

Next.js has strong opinions about how to organize JavaScript but not CSS. How can we develop patterns that encourage best CSS practices while also following the framework’s logic? The answer is surprisingly simple — to write well-structured CSS that balances global and local styling concerns. In this article, Alexander Dubovoy will build a website (a tea shop!) to demonstrate these patterns.

Data grids need to be easy to understand, engaging, responsive, and accessible. They need to perform well and load data fast. However, building a data grid that meets these standards from scratch can take a long time and be a huge undertaking. In this article, you’ll get to see some pretty groundbreaking things you can achieve with modern JavaScript grids. You’ll learn how these data tables solve the problems described earlier. Additionally, you’ll discover new ways to augment a data grid to make it engaging, responsive, and accessible. All this will be illustrated using Kendo UI Data Grids and their features.

Have you ever needed to build a UI where some component on the page needs to respond to elements as they’re scrolled to a certain threshold within the viewport — or perhaps in and out of the viewport itself? In JavaScript, attaching an event listener to constantly fire a callback on scroll can be performance-intensive, and if used unwisely, can make for a sluggish user experience. But there is a better way with Intersection Observer.
