Enhancing Angular Applications with HTTP Interceptors for Authentication and Retry Logic
Introduction When working with Angular applications, handling authentication tokens and retrying failed HTTP requests are common challenges. Angular provides a powerful feature called HTTP Interceptors, which allows developers to: ✅ Automatically attach authentication tokens to outgoing requests ✅ Retry failed requests automatically ✅ Centralize HTTP request modifications for cleaner code In this blog, we will explore how to create and use HTTP Interceptors in Angular for: 1️⃣ Adding Authorization Headers dynamically 2️⃣ Retrying Failed Requests Automatically We will also demonstrate how to test an HTTP interceptor dynamically using an input-based API URL fetcher.
