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.

Angular Animations: Animate to Unknown Height (Deprecated Module)

March 29, 2024

Animating to an unknown height is impossible with pure CSS—you can't transition to auto or 100%, and max-height workarounds require arbitrary values that break in edge cases. Angular's animation framework solves this by calculating the actual height at runtime and animating to that value, creating smooth expand/collapse effects for accordions, dropdowns, and dynamic content. This tutorial demonstrates how to animate elements to their natural height, regardless of content size. Note: This uses Angular's deprecated animations module.

Angular Animations: Animate Multiple Items in Parallel (Deprecated Module)

March 15, 2024

Angular animations run sequentially by default, which works for simple transitions but breaks complex animations where multiple properties need to change simultaneously. Parallel animations are essential for coordinated effects like simultaneous fade and slide transitions, or when animating multiple elements together. This tutorial shows you how to run multiple animations in parallel using Angular's animation API, creating more sophisticated and professional effects. Note: This uses Angular's deprecated animations module.
