What is the purpose of an HttpInterceptor in Angular?

  • Intercept and modify HTTP requests and responses
  • Manage application state

  • Validate form input
An HttpInterceptor in Angular is used to intercept and modify HTTP requests and responses before they are sent to or received from the server. This allows you to add headers, handle errors, perform logging, or make any necessary changes to the request or response pipeline globally across your application. It is a powerful tool for managing HTTP-related behaviors in a centralized manner.
