fix(nextjs): refresh the session from the client before the access token expires - #560
Conversation
…ken expires Tokens were only refreshed by the middleware on navigation. A long-lived page, or an app set up without the middleware, silently lost its session once the access token expired although the refresh token was still valid; the refreshToken server action existed but nothing called it. - AsgardeoProvider passes the session expiry to the client provider, which refreshes shortly before it and reschedules from the action's result. - refreshToken accepts `onlyIfExpiring`, so the scheduled refresh is a no-op when the middleware has just refreshed the session and the two never race on the same refresh token. - On failure the client re-renders the server components so the signed-out state is picked up.

📝 WalkthroughWalkthroughThe Next.js providers now expose session expiry to the client. The client schedules token refreshes before expiry and reschedules from the returned expiry. The server action skips refreshes for sessions outside the refresh buffer. Tests cover refresh, skip, failure, and missing-session flows. ChangesNext.js token refresh

Line 131 deletes the cookie for network errors and all non-OK token-endpoint responses. The new client scheduler calls this action while the current access token is still valid. A temporary outage then clears a usable session, and

Problem
The access token was only refreshed by the middleware, i.e. on navigation. The client provider received the
refreshTokenserver action but never called it (the action's own comment referred to arefreshOnMountthat does not exist), andRefreshResult.expiresAtwas unused. Consequences:http.request, although the refresh token is still valid;The React SDK refreshes automatically before expiry.
Fix
AsgardeoServerProviderpasses the session's expiry (expof the session cookie) to the client provider.refreshTokenshortly before expiry (REFRESH_BUFFER_SECONDS, with a 5 s floor so an already expired token is refreshed immediately without a tight loop) and reschedules from the returnedexpiresAt. When a refresh fails it callsrouter.refresh()so the server components pick up the signed-out state.refreshTokengains anonlyIfExpiringoption: the scheduled refresh uses it, so when the middleware has just refreshed the session for a recent request the action returns the current expiry without a second exchange. This avoids two refreshes racing on the same (rotating) refresh token. Direct calls throughuseAsgardeo().refreshToken()keep refreshing unconditionally.Testing
refreshTokenunit tests: exchange + cookie write + returned expiry,onlyIfExpiringskipping a fresh session,onlyIfExpiringrefreshing an expiring one, cookie cleared on failure, no session cookie (65 tests pass).pnpm lintandtsc --noEmitfor@asgardeo/nextjs.
