TypeScript Development

Type-safe JavaScript development that catches bugs before they reach production.

We build enterprise-grade applications with TypeScript's powerful type system, delivering codebases that are safer, more maintainable, and self-documenting. Our TypeScript expertise spans frontend frameworks, backend services, and full-stack applications with end-to-end type safety.

What We Offer

TypeScript capabilities

End-to-End Type Safety

Full-stack type safety from database schema to API layer to frontend using Prisma, tRPC, and Zod for zero-gap type coverage across your entire application.

Legacy JS Migration

Incremental migration strategies that convert JavaScript codebases to TypeScript without disrupting development velocity or introducing regressions.

Advanced Type Patterns

Leverage generics, mapped types, conditional types, and template literal types to create flexible, reusable abstractions that reduce boilerplate code.

Shared Type Libraries

Monorepo-friendly type packages shared between frontend, backend, and mobile applications for consistent data contracts across your entire product.

Runtime Validation

Combine compile-time types with runtime validation using Zod, io-ts, or Valibot to ensure external data (APIs, forms, files) matches expected types.

Developer Tooling

Enhanced IDE support with auto-completion, inline documentation, refactoring tools, and error detection that dramatically improves developer productivity.

FAQ

Frequently asked questions

Should we migrate our existing JavaScript project to TypeScript?+
If your codebase is growing, has multiple contributors, or suffers from runtime type errors, migration is highly recommended. We use an incremental approach, starting with strict mode on new files while gradually converting existing code.
Does TypeScript slow down development?+
Initially there is a small learning curve, but TypeScript significantly accelerates development over time. Auto-completion, inline documentation, and compile-time error detection reduce debugging time by up to 85% and make refactoring 3x faster.
How do you handle TypeScript in a monorepo?+
We use Turborepo or Nx to manage monorepos with shared TypeScript packages. Project references, composite builds, and path aliases ensure fast compilation and consistent type checking across all packages.
Can TypeScript be used for backend development?+
Absolutely. TypeScript with Node.js (NestJS, Fastify) is one of the most popular backend stacks. Combined with Prisma for database access and Zod for validation, you get full-stack type safety from database to browser.
What TypeScript strictness level do you recommend?+
We always recommend strict mode with additional rules like noUncheckedIndexedAccess and exactOptionalPropertyTypes. Stricter settings catch more bugs at compile time and result in more robust, self-documenting code.
