## What it is
An Angular library that provides an HttpInterceptor to automatically attach JSON Web Tokens to HttpClient requests. It handles token attachment only and leaves authentication flows and token retrieval to the developer.

## Use cases
- attach jwt tokens to http requests in angular
- add authorization header automatically in angular app
- send bearer token with httpclient requests
- manage jwt in local storage for angular
- exclude certain routes from token attachment
- handle token-based auth in angular 2+

## When to choose
- you already have a JWT and need it attached to Angular HttpClient requests
- you want a lightweight, unopinionated token interceptor
- you use Auth0 or another provider that issues JWTs

## When to avoid
- you need full authentication flows like login, signup, or token refresh
- you are not using Angular
- you need token validation or decoding as a core feature

## Facets

- maturity: active
- function: auth, http-client, middleware
- domain: web-development, frontend, security, apis
