After social auth (GitHub/Google), the backend redirects to the root page / which was a static server component showing only a loading spinner. The pending OAuth authorize URL stored in localStorage was never consumed, causing users to get stuck instead of returning to the OAuth authorization flow.

Convert root page to a client component that checks localStorage for a pending OAuth redirect on mount and navigates accordingly.

Summary of Changes

Hello @RockChinQ, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses a critical bug in the social authentication flow where users were not correctly redirected to the OAuth authorization page after logging in. By transforming the root page into a client-side component, the application can now properly detect and utilize stored OAuth redirect URLs, ensuring a seamless and functional authentication experience.

Highlights

  • OAuth Redirect Fix: Resolved an issue where users were stuck on a loading page after social authentication due to unconsumed pending OAuth authorize URLs, preventing proper redirection to the OAuth flow.
  • Root Page Conversion: The root page ('/') has been converted into a client component that now actively checks for and handles pending OAuth redirects stored in 'localStorage' upon mounting.
  • Utility Function Refactor: The utility function 'getItemWithExpiry' in 'post-login-redirect.ts' was renamed to 'getOAuthPendingRedirect' and exported to support its use in the new client-side root component.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Changelog
  • web/app/page.tsx
    • Converted the component from a server component to a client component.
    • Implemented a 'useEffect' hook to check for and redirect to pending OAuth authorization URLs stored in 'localStorage'.
    • Added necessary imports for 'useRouter', 'useEffect', and OAuth-related constants and utilities.
  • web/app/signin/utils/post-login-redirect.ts
    • Renamed the internal utility function 'getItemWithExpiry' to 'getOAuthPendingRedirect' and made it an exported function.
    • Updated the call site within 'resolvePostLoginRedirect' to use the new function name.

Code Review

This pull request aims to resolve the issue of users getting stuck after social authentication by implementing a client-side redirect from the root page. However, it introduces a potential Open Redirect vulnerability because the redirect target from localStorage is not validated before use. Additionally, an improvement is needed in the useEffect hook in web/app/page.tsx to align with Next.js best practices.

The application retrieves a redirect URL from localStorage and passes it directly to router.replace() without validation. This introduces a potential Open Redirect vulnerability, allowing an attacker to redirect users to a malicious external website. The provided suggestion validates that pendingRedirect is a safe, internal path (e.g., starts with a single / and not //). Additionally, the useEffect dependency array includes router, which is not guaranteed to be stable; for an effect that should run once on mount, an empty dependency array [] is recommended for useEffect.

Suggested change
const pendingRedirect = getOAuthPendingRedirect(OAUTH_AUTHORIZE_PENDING_KEY)
if (pendingRedirect) {
router.replace(pendingRedirect)
const pendingRedirect = getOAuthPendingRedirect(OAUTH_AUTHORIZE_PENDING_KEY)
if (pendingRedirect && pendingRedirect.startsWith('/') && !pendingRedirect.startsWith('//')) {
router.replace(pendingRedirect)
return
}
