TypeScript development and code quality services
TypeScript adds type safety to JavaScript and is the default output for most AI coding tools. However, AI-generated TypeScript often uses 'any' types, incorrect generics, and missing strict mode - defeating the purpose.
Common TypeScript issues we find
Real problems from TypeScript codebases we've reviewed.
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.
Missing API response types
API calls return unknown or any types, so the compiler can't catch errors when accessing response data.
Inconsistent error types
Errors caught as 'unknown' or 'any' without proper narrowing, leading to unsafe property access on error objects.
Unused exports and dead code
Exported functions, types, and variables that are never imported - increasing bundle size and code complexity.
Build configuration issues
Incorrect module resolution, missing path aliases, and tsconfig settings that cause deployment failures.
TypeScript production checklist
Key checks before deploying your TypeScript app.
strict: true in tsconfig.json
No 'any' types (use 'unknown' + type guards)
API response types defined and validated at runtime
Proper error narrowing in catch blocks
No unused exports or dead code
Consistent use of interfaces vs types
Path aliases configured and working in production builds
Proper enum usage (const enums or union types)
Generic constraints where needed
Discriminated unions for state management

Frequently asked questions
Why does my AI-generated TypeScript have so many 'any' types?
AI tools use 'any' to avoid type errors quickly. We replace them with proper types, enabling TypeScript to actually catch bugs at compile time.
Should I enable strict mode?
Absolutely. Strict mode catches entire categories of bugs. We enable it and fix the resulting type errors - it's one of the highest-impact improvements you can make.
Can you improve the types in my codebase?
Yes. We replace 'any' with proper types, add API response validation, fix generic implementations, and ensure type safety throughout your app.
Is TypeScript worth the overhead?
Yes - when used properly. AI-generated TypeScript with 'any' everywhere gives you the overhead without the benefits. We make it work as intended.
