Angular HttpClient vs Fetch: Which Should I Use?

What are the main differences between Angular HttpClient and the Fetch API?

Angular HttpClient is a built-in service for making HTTP requests in Angular applications, while Fetch is a native JavaScript API for making network requests. HttpClient provides features like observables, automatic JSON parsing, and interceptors, whereas Fetch is more low-level and requires manual handling of responses.

When should I use HttpClient over Fetch?

You should use HttpClient when working within an Angular application, as it integrates seamlessly with Angular's features. Use Fetch for simpler projects or when you need a lightweight solution without Angular's overhead.

Can I use Fetch in an Angular app?

What are the performance differences between the two?

In general, both HttpClient and Fetch have similar performance for most use cases. However, HttpClient may have a slight overhead due to its additional features, while Fetch is more lightweight.
