Get to Know The HttpResource In Angular
Before the introduction of the #ResourceAPI, #angular developers often struggled to find effective patterns to make HTTP requests based on changes to signal values.
The Resource API simplifies making HTTP requests based on signal changes:
Declarative requests: Define HTTP requests that automatically trigger when the source signal updates.
Improved reliability: The API is designed to handle race conditions and prevent unpredictable application states.
Built-in loading state: The Resource API provides a built-in loading state, making it easy to display loading indicators to users without needing custom logic.
The #HttpResource is a vanilla implementation of the Resource API and in this video you will see:
