Fix persisted authentication after page reload

[githubsaturn]

What changed

• Restore the authentication token from browser storage when the frontend initializes
• Add regression coverage for localStorage, sessionStorage, and the no-token case

Root cause

The migration to the caprover-api package changed the in-memory authentication provider to always start with an empty token. A page reload therefore treated persisted sessions as logged out, and the unauthorized flow could clear the valid stored token.

Impact

The "Use localStorage" and "Use sessionStorage" login options now survive reloads as intended. "No session persistence" remains unchanged, and invalid stored tokens are still cleared by the existing authentication failure flow.

Fixes caprover/caprover#2456

Validation

• Added focused module-initialization regression tests for both persistence modes and the logged-out case
• Inspected the remote commit diff
• CI checks will run on this pull request

Summary by CodeRabbit

• Bug Fixes

  • Correctly starts the app in a logged-out state when no stored token is available.

• Tests

  • Added coverage for token restoration from local and session storage, as well as logged-out initialization.

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.

📝 Walkthrough

Walkthrough

ApiManager now restores its initial authentication token from browser storage. Tests verify localStorage, sessionStorage, and missing-token initialization states.

Changes

Authentication initialization

Layer / File(s)	Summary
Token restoration and initialization tests src/api/ApiManager.ts, src/api/ApiManager.test.ts	ApiManager initializes authProvider.authToken with StorageHelper.getAuthKeyFromStorage(). Tests verify logged-in states for stored tokens and a logged-out state when no token exists.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 75071

The change restores persisted authentication after reload, but the new tests do not verify the exact restored token and could pass with an incorrect non-empty value. This is a bounded follow-up risk, so the PR is mergeable with owner awareness.

verify the exact restored values local-token and session-token, using the
