Resource Signal with Params #angular19 #angular #techshareskk #reactivity

*Summary*

This video tutorial explains Resource Signals, a new feature in Angular 19 (currently in developer preview), designed for handling asynchronous data. It demonstrates how to create a resource signal using the `resource` function, incorporating loaders (e.g., using `fetch`) to retrieve data from an API. The tutorial covers displaying data in the UI, handling loading states with placeholders, and using the `reload` function for refreshing data without a full page reload. It also shows how to create a dynamic resource signal that updates based on changes to a signal holding an ID, fetching specific items from the API.

*Highlights*
- 🚀 *Resource Signals for Asynchronous Data:* Angular 19 introduces Resource Signals to efficiently manage asynchronous operations, especially fetching data from APIs.

- 🔄 *Loading Indicators and State Management:* The tutorial demonstrates how to effectively manage loading states using the `isloading` property of the resource signal, displaying placeholders until data is available.

- ➡️ *Dynamic Data Fetching:* The video showcases how to build a resource signal that dynamically updates based on a signal representing an ID, enabling fetching of specific data items.

- ♻️ *Efficient Reloading:* Using the `reload` function allows for refreshing data from the API without triggering a full page reload, improving user experience.

- 💻 *Practical Example with To-Do API:* A complete example using a to-do API illustrates how to implement and utilise Resource Signals effectively within an Angular application.
