Add Features for your GPT Engineer-built Express app
Expert add features for Express apps built with GPT Engineer. We audit GPT Engineer-generated Express code for add features issues. From $19.
GPT Engineer issues we find in Express projects
Problems specific to GPT Engineer's code generation patterns when building Express apps.
No authentication system
GPT Engineer generates functional UIs but typically skips authentication entirely. All routes and data are publicly accessible.
Direct database access from client
Some generated apps query databases directly from the frontend without an API layer, exposing database credentials and structure.
Incomplete feature implementations
Features that look complete in the UI but don't actually work end-to-end. Buttons that don't submit, forms that don't save, and links that go nowhere.
Express add features issues we check for
Add Features-specific Express problems that need attention before production.
Unstructured error handling
No global error-handling middleware. Errors either crash the process, leak stack traces to clients, or get silently swallowed with no logging.
Blocking the event loop
CPU-intensive operations like JSON parsing of large files, image processing, or heavy computation done on the main thread, blocking all other requests.
