Engineering Highlights
Express/Next.js Authentication Redirection Loop Fix
Security & Session ManagementIssue Detected
Dashboard interface would lock up in an infinite redirect spinner when a user session expired or a token cookie signature was invalid.
Root Cause Diagnosis
Next.js middleware detected the 'token' cookie existence and routed users to the secure dashboard page, which requested profile info. The backend returned 401 Unauthorized because the token was expired, redirecting the user to '/login'. The middleware intercepted '/login', saw the token cookie was still present in the browser, and redirected back to the dashboard, creating an infinite loop.
Resolution & Impact
Enhanced the Express backend authenticateJWT middleware to immediately invoke res.clearCookie('token') upon token validation or signature mismatch failures. This ensures the invalid cookie is instantly purged from the browser, allowing the client-side router to land cleanly on the login page.
- } catch (err) {
- res.status(401).json({ error: 'Unauthorized' });
- }
+ } catch (err) {
+ res.clearCookie('token');
+ res.status(401).json({ error: 'Unauthorized. Token cleared.' });
+ }AI Cosine Similarity Search Scaling Optimization
System Scaling & OptimizationIssue Detected
Evaluating cosine similarity for user queries in-memory blocks the single-threaded Node.js event loop as the total number of files in the database grows.
Root Cause Diagnosis
Iterating over high-dimensional vector embeddings (1,536 dimensions) for all database records in-memory scales at O(N) globally, consuming unnecessary memory and CPU overhead.
Resolution & Impact
Restructured the search pipeline to query and filter active file records by the specific workspace ID at the database level first. This confines the similarity calculations to only the files belonging to the active workspace.
// Restricting search array at DB layer first
- const allFiles = await File.find({});
+ const workspaceFiles = await File.find({
+ workspaceId: req.params.workspaceId,
+ deletedAt: null
+ });The Stack I Ship With
