Nobody Wants to See a Blank Screen… Build Smarter Loaders!

May 08, 2025

Blank screens and generic spinners create poor user experiences, making apps feel slow even when they're loading quickly. Skeleton loaders improve perceived performance by showing UI structure immediately, providing visual feedback, and creating smooth transitions to real content. This tutorial demonstrates how to build skeleton loaders using Angular's deferred loading, signals for state management, and animations for smooth transitions. Note: This uses Angular's deprecated animations module—modern alternatives are available.

Angular Component Theming: CSS Custom Properties and :host-context

February 27, 2025

Component theming in Angular requires understanding how styles cascade and how to adapt components to different contexts. This tutorial demonstrates multiple theming strategies using CSS :host and :host-context selectors, along with CSS custom properties. You'll learn how to create flexible components that adapt their appearance based on where they're used, whether in a sidebar, main content area, or different color schemes. Each approach has trade-offs that we'll explore in detail.

Angular View vs Content: Understanding Signal Queries

February 20, 2025

The difference between "view" and "content" in Angular trips up many developers, leading to queries that don't work as expected. Understanding this distinction is crucial for working with signal queries like viewChild() and contentChild(). This tutorial explains the fundamental difference: "view" refers to a component's own template, while "content" refers to projected content from parent components. You'll learn when to use each query type and how to avoid common mistakes.

Untagged Template Literals... The Upgrade You Didn’t Know You Needed!

February 13, 2025

Dynamic class and style bindings in Angular templates often become complex, mixing string concatenation, ternary operators, and multiple bindings that are hard to read and maintain. Angular's template literal syntax provides a cleaner way to handle dynamic expressions, allowing you to use JavaScript template literals directly in templates for classes, styles, and complex interpolations. This tutorial demonstrates how to use template literals to simplify dynamic bindings and improve template readability.
