Описание: Summary

This video tutorial explains how to use Angular 19's output signals, a higher-performance replacement for the output decorator introduced in Angular 18. It demonstrates migrating a child component from using the output decorator to using output signals, highlighting the benefits of improved performance and simplified syntax. The tutorial also covers the use of aliases for output signals.

Highlights

🚀 Output Signals in Angular 19: The video focuses on the improved performance and streamlined syntax of output signals compared to the older output decorator.
🛠️ Migration from Output Decorator: A step-by-step guide demonstrates migrating an existing component using the output decorator to use output signals via the `ng generate @angular/core:signal-output-migration` command.
💡 Simplified Syntax: The tutorial shows how the signal-based approach simplifies the code compared to using `EventEmitter`.
🏷️ Alias Names: The use of alias names for output signals is explained, allowing for more readable and maintainable code.
💻 Practical Example: A complete example using a parent and child component illustrates the process of emitting data from child to parent using both the old and new methods.
