Repeated Axios 401s usually mean a token lifecycle bug, not an API bug. Diagnose header attachment, interceptor order, single-flight refresh, and retry loops in order.
A practical axios v1.x pattern: use a response interceptor to catch 401s, refresh the auth token once, and retry the original request — with the loop guard and shared-promise tricks that keep it safe under concurrency.
Scattered Authorization headers and repeated 401 handling create fragile code. Using axios request and response interceptors on a custom instance centralizes token attachment and single‑refresh retry logic, with ordering caveats and verification steps.
Goal Determine whether k6 should extend its HTTP module with built‑in token refresh logic to automatically handle expired bearer tokens or API keys during a load test. Constraints The current core runtime leaves authentication entirely to the test script; adding automatic refresh would introduce runtime dependencies, version‑sensitive behavior, and potential
Goal Design a least‑privilege authentication flow where each Axios request carries only the scopes it needs and expired credentials are refreshed transparently. Constraints Axios provides per‑request auth config and response interceptors, but it lacks a built‑in queue or deduplication mechanism for token refresh. When several concurrent requests encounter a
Problem: invalid_grant on restored token Goal: Determine how an OAuth 2.0 authorization server handles a refresh token that has been restored from backup after it has been revoked or expired. Constraints: The spec does not mandate token rotation; some servers reuse the same refresh token, others issue a new one. Backup restoration may bring an old token that
When using the Nuxt Auth module to protect routes, an expired JWT access token causes the router to redirect the user to the login page. The module’s documentation does not state whether this expiry also triggers a global error handler or emits an event that can be captured by analytics or error‑tracking tools. Developers need to know if token‑expiry can be
Goal: Ensure that Angular applications enforce least‑privilege access through route guards while gracefully handling expired JWT credentials. Constraints: Route guards execute synchronously; any asynchronous token validation must return a Promise or Observable, which can affect navigation timing. An HttpInterceptor can detect 401 responses, but automatically
Goal: Least‑Privilege Authentication with Robust Token Refresh In a Xamarin.Forms app, the objective is to request only the scopes required for a feature, store the resulting access and refresh tokens securely, and refresh the access token silently when it expires. The design must also handle the case where the refresh token itself becomes invalid (revoked o
