TypeScript app built with Codex CLI? Let’s review it.
Expert code review for TypeScript apps built with Codex CLI. We find Codex CLI-specific bugs, fix TypeScript security issues, and optimize performance. From $19.
Codex CLI issues we find in TypeScript projects
Problems specific to Codex CLI's code generation patterns when building TypeScript apps.
API keys and secrets written directly into generated source files
Codex CLI generates code with placeholder credentials that developers often replace with real values inline, leaving secrets committed to version control. There is no .env scaffolding or secret management setup by default.
No authentication or authorization on generated API endpoints
When Codex generates Express or FastAPI backends, routes are created without middleware for authentication, meaning every endpoint is publicly accessible immediately after deployment.
Single-file output breaks apart for any real project structure
Codex frequently outputs all logic into one or two files rather than organizing code into modules, services, and utilities — making the result hard to maintain and extend as the codebase grows.
Generated code lacks awareness of existing project context
Because Codex operates from a prompt without full codebase indexing, it generates code that duplicates existing utilities, ignores established conventions, and introduces conflicting patterns alongside your real code.
TypeScript issues we check for
Common TypeScript problems that affect production readiness.
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.
Missing strict mode
tsconfig.json without strict mode enables sloppy type checking that allows null errors and implicit any types.
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.
Incorrect generic implementations
Overly complex or incorrect generic types that confuse rather than help, making the code harder to maintain.
