Resolving JWT Refresh Token Handling in Angular with HttpInterceptor

For secure applications, controlling JWT token refresh in Angular is crucial. An HttpInterceptor allows you to automatically refresh tokens, manage 401 errors, and intercept requests without interfering with the user experience. However, an effective strategy is needed to coordinate these procedures so that updated tokens are applied to next requests. Using BehaviorSubject and queuing requests during refresh are two strategies that help minimize server load and avoid making duplicate API calls. This post explores doable strategies to enhance token handling, giving consumers better security and performance.
