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.

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.

Just Another Angular CDK Feature Nobody Talks About

July 17, 2025

Treating all focus events identically creates poor user experiences—keyboard users see aggressive error messages meant for mouse interactions, and programmatic focus triggers unwanted UI changes. The Angular CDK's Focus Monitor detects how users interact with elements, distinguishing between mouse clicks, keyboard navigation, touch, and programmatic focus. This tutorial demonstrates how to use Focus Monitor to create adaptive UIs that respond intelligently to different interaction patterns, improving accessibility and user experience.

exportAs in Angular: What It Does and When to Use It

May 22, 2025

Directives with public methods or signals need a way to expose their API to parent components, but accessing directive instances from templates requires explicit references. Angular's exportAs property lets you create template references to directives, enabling access to their methods, signals, and properties directly in templates. This tutorial demonstrates how to use exportAs to create reusable directives with clean, declarative APIs, following patterns used by Angular Material components.

How to Build a Resizable Sidebar in Angular (Step-by-Step)

April 17, 2025

Resizable sidebars improve UX by letting users customize layouts, but implementing drag-to-resize functionality requires handling mouse events, calculating dimensions, and managing state. The Angular CDK Drag and Drop module simplifies this by providing built-in drag handling, boundary detection, and state management. This tutorial demonstrates how to build a resizable sidebar using only the Angular CDK, creating a professional drag-to-resize experience without external libraries.

Angular CDK Auto-Resizing Textareas: Dynamic Height Control

June 28, 2024

Fixed-height textareas create poor user experiences when content exceeds the visible area, forcing users to scroll within a small box. Auto-resizing textareas improve UX by expanding to fit content, eliminating scrollbars, and providing visual feedback as users type. The Angular CDK TextField module includes a directive that handles all the complexity of auto-resizing textareas, including proper height calculations and performance optimizations. This tutorial shows you how to implement auto-resizing textareas in minutes.

Angular toSignal(): Convert Observables to Signals (v19+)

April 07, 2024

Converting Observables to signals in Angular eliminates the need for async pipes, simplifies change detection, and reduces template complexity. While Observables excel at event streams and async operations, signals provide better performance for UI state that needs to update reactively. Angular's toSignal() function bridges these worlds, letting you transform Observable streams into reactive signals. This tutorial shows you how to convert common Observable patterns to signals, when to use each approach, and how to optimize performance.
