Make Any List Draggable in Minutes

October 09, 2025

Drag-to-reorder functionality improves UX by letting users customize list order, but implementing it requires handling drag events, calculating drop positions, and managing list state. The Angular CDK Drag and Drop module simplifies this with directives that handle all drag complexity, including visual feedback, drop zones, and reordering logic. This tutorial demonstrates how to add drag-to-reorder functionality to any Angular list using the CDK Drag and Drop module, requiring minimal code and no external libraries.

Animation Start/Done? Dead. Long Live CSS + DOM Events

October 02, 2025

Angular's deprecated animations module provided start and done events for coordinating animations with component logic, but modern Angular requires a different approach. This tutorial demonstrates how to replace animation start/done events using pure CSS keyframes, Angular signals, and standard DOM events. You'll learn how to detect animation completion, coordinate multiple animations, and trigger side effects when animations finish, all without the deprecated module.

Make Any List Keyboard-Friendly in Minutes

September 25, 2025

Keyboard navigation in lists requires handling arrow keys, home/end keys, type-ahead search, and focus management, but implementing this manually is complex and error-prone. The Angular CDK ListKeyManager provides a complete solution for keyboard-accessible lists, handling all navigation patterns automatically. This tutorial demonstrates how to use ListKeyManager to make any list keyboard-friendly, ensuring your Angular applications are accessible to all users without manual keyboard event handling.

Teleport a Component in Angular (and Keep Its State)

September 18, 2025

Moving components to different DOM locations in Angular typically destroys component state because Angular recreates views when templates change. The Angular CDK DomPortal provides a solution by moving live DOM elements without destroying component instances, preserving state, event listeners, and component lifecycle. This tutorial compares three approaches: ng-template with ngTemplateOutlet, CDK Template Portal, and CDK DomPortal, showing when each preserves state and when components get recreated.

Can You Even Use Jump Links in Angular? (Yes… Here’s How)

September 11, 2025

Jump links improve navigation in long-form content, but Angular's routing system breaks standard HTML anchor links. Implementing jump links in Angular requires handling router navigation, smooth scrolling, and ensuring links work across different route configurations. This tutorial demonstrates how to create router-friendly jump links that work seamlessly with Angular's routing system, providing smooth scrolling and proper navigation handling.

Modern Angular Animations: Ditch the DSL, Keep the Power

September 04, 2025

Angular's deprecated animations module leaves developers wondering how to create advanced animations without the DSL. The modern approach combines Angular's new enter/leave animation primitives with pure CSS animations, providing better performance, hardware acceleration, and simpler code. This tutorial demonstrates how to build complex animations including staggered list animations, sequential effects, and coordinated multi-element transitions using modern Angular animation techniques.

The Many Personalities of Angular’s viewChild (the Read Parameter)

August 28, 2025

Angular's viewChild() signal query is powerful, but the read parameter unlocks advanced scenarios most developers never discover. Instead of just querying components and elements, you can read specific tokens, directives, or providers, accessing lower-level APIs and creating more flexible component architectures. This tutorial demonstrates how to use the read parameter to query ElementRef, ViewContainerRef, TemplateRef, and custom tokens, showing real-world examples that simplify component code.

Tired of Console Logs? Meet Angular’s Signal Graph

August 21, 2025

Debugging signal dependencies in Angular applications is challenging without visibility into signal relationships and update chains. Angular 20.1 introduced the Signal Graph debugging tool, providing visual representation of signal dependencies, update flows, and reactive relationships. This tutorial demonstrates how to install and use the Signal Graph to understand your application's reactive architecture, debug signal issues, and optimize signal-based code.
