Add Features for your GPT Engineer-built TypeScript app

Expert add features for TypeScript apps built with GPT Engineer. We audit GPT Engineer-generated TypeScript code for add features issues. From $19.

GPT Engineer issues we find in TypeScript projects

Problems specific to GPT Engineer's code generation patterns when building TypeScript apps.

highSecurity

No authentication system

GPT Engineer generates functional UIs but typically skips authentication entirely. All routes and data are publicly accessible.

highSecurity

Direct database access from client

Some generated apps query databases directly from the frontend without an API layer, exposing database credentials and structure.

mediumBugs

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.

TypeScript add features issues we check for

Add Features-specific TypeScript problems that need attention before production.

bugs

Excessive use of 'any' type

AI tools use 'any' to bypass type errors instead of defining proper types, removing all the safety benefits TypeScript provides.

bugs

Missing strict mode

tsconfig.json without strict mode enables sloppy type checking that allows null errors and implicit any types.

bugs

Type assertions instead of type guards

Using 'as' casts to force types instead of runtime checks, causing crashes when data doesn't match the asserted type.
