Warning

Review limit reached

@kavix, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 46 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Adds the Express singleton client, sign-in and sign-out delegation, session cookies, route protection, and authentication middleware.
Express models, constants, utilities, and exports
packages/express/src/models/*, packages/express/src/constants/*, packages/express/src/utils/*, packages/express/src/index.ts
Adds Express configuration and callback types, defaults, logging configuration, URL inspection, barrels, and named exports.

Repository cleanup

Layer / File(s) Summary
Legacy-folder migration metadata and tooling
.changeset/remove-legacy-folders.md, packages/vue/tsconfig.lib.json, scripts/aggregate-changelogs.js
Records the package patch release, removes the Vue legacy exclusion, and allows legacy directories in changelog aggregation.

Estimated code review effort: 5 (Critical) | ~120 minutes

Mergeability Score: 🔴 Critical · up to 2a6fd

This refactor currently contains build-blocking TypeScript errors and concrete authentication, session, token, middleware, and browser lifecycle defects, including corrupted persisted configuration, unsafe session handling, malformed token requests, and operations that can hang or leak resources. It is not merge-ready until the blocking correctness and security issues are fixed.

Await authentication initialization before exposing the core.

AsgardeoAuthClient.initialize writes the configuration asynchronously. AsgardeoNodeCore exposes the storage manager before this write completes. A first request can read incomplete configuration, and a rejected initialization promise is unhandled. The Express client also discards LegacyAsgardeoNodeClient.initialize's promise.

Use an async factory or an async core initialization method. Resolve LegacyAsgardeoNodeClient.initialize only after this.auth.initialize(...) completes.

Three token endpoints build form bodies without percent-encoding. Each site concatenates raw keys and values and joins them with &.

The explicit idToken argument is ignored when a session exists.

The default is 3000, so a call without an argument waits 3,000,000 ms (50 minutes). packages/browser/src/clients/web-worker-client.ts calls SPAUtils.waitTillPageRedirect() with no argument in the sign-in and sign-out paths, so those promises stay pending long after the redirect decision.

+    const timeToWait = time ?? 3;

Close the message channel when the request times out.

The timeout path rejects the promise but leaves channel.port1 and channel.port2 open, and it leaves port1.onmessage registered.

Clear the previously scheduled timer before you schedule a new one.

refreshAccessTokenAutomatically is called on every successful refresh and after every token exchange. See refreshAccessToken (line 190) and exchangeToken (line 147) in packages/browser/src/helpers/authentication-helper.ts. Each call schedules a new setTimeout and overwrites REFRESH_TOKEN_TIMER with the new id. The previous timer stays active and its id is lost, so it can no longer be cleared.

Set _hasRefreshFailed when the refresh fails.

refreshAccessToken clears _hasRefreshFailed on success (line 189) but never sets it on failure. Only isSignedIn sets the flag (line 744). Refresh attempts that start from httpRequest (line 278) or from the scheduled timer in packages/browser/src/helpers/spa-helper.ts (line 61 and line 73) therefore leave the flag false after a failure.

SPAHelper.refreshAccessTokenAutomatically reads authenticationHelper.hasRefreshFailed() at line 57 to stop repeated attempts. With the flag unset, an expired or revoked refresh token produces repeated refresh grant requests to the token endpoint.

Set the flag in the catch block.

Clear the previously scheduled timer before you schedule a new one.

refreshAccessTokenAutomatically is called on every successful refresh and after every token exchange. See refreshAccessToken (line 190) and exchangeToken (line 147) in packages/browser/src/helpers/authentication-helper.ts. Each call schedules a new setTimeout and overwrites REFRESH_TOKEN_TIMER with the new id. The previous timer stays active and its id is lost, so it can no longer be cleared. Over a long session the timers accumulate and fire redundant refresh grant requests. _isTokenRefreshLoading only prevents overlapping refreshes; it does not prevent duplicate scheduled timers.

Use the imported OP_IFRAME constant. The local declaration duplicates the imported value "opIFrame" and creates unnecessary shadowing.

Return getConfigData from WebWorkerCore.

Line 66 requires getConfigData. packages/browser/src/worker/worker-core.ts declares Promise<WebWorkerCoreInterface> but omits this method from its returned object. TypeScript will reject the returned object and block the browser package build.

Remove the undeclared session property.

TokenResponse does not declare session. This fresh object literal fails TypeScript excess-property checking and prevents the package from type-checking.

Proposed fix
       return Promise.resolve({
         accessToken: '',
         createdAt: 0,
         expiresIn: '',
         idToken: '',
         refreshToken: '',
         scope: '',
-        session: '',
         tokenType: '',
       });
