JavaScript at scale,
typed and maintainable.
TypeScript is the default on every JavaScript project we ship — frontend or backend. The type system catches bugs at compile time, makes refactoring safe, and keeps large codebases readable. After 8 years and 600+ projects, we don't write untyped JavaScript for production anymore.
TypeScript across the full stack — frontend and backend
TypeScript isn't a framework — it's a layer of correctness on top of JavaScript that pays dividends throughout a project's lifetime, not just at the start.
TypeScript React Applications
Fully typed React applications with typed props, hooks, context, and API responses. Refactoring a typed React codebase is dramatically safer than refactoring plain JavaScript.
TypeScript Node.js Backends
Express and NestJS backends with typed request/response objects, database query types, and shared interfaces. API contracts between frontend and backend enforced at compile time.
Shared Type Libraries
Monorepo type packages shared across frontend and backend — one source of truth for API contracts, domain models, and validation schemas. No more frontend/backend type drift.
JavaScript to TypeScript Migration
Migrating existing JavaScript codebases to TypeScript incrementally — adding types file by file, tightening strictness over time, without rewriting the whole application at once.
The investment that pays back every sprint after the first
TypeScript adds upfront cost — writing types, fixing type errors. The payback is faster refactoring, fewer runtime bugs, and onboarding new developers in days instead of weeks.
Bugs caught at compile time
Null pointer exceptions, wrong property names, missing function arguments, type mismatches — TypeScript catches these before they reach your CI pipeline. We see a measurable reduction in runtime errors on typed projects.
Refactoring becomes safe
Rename a function or change an API response shape — TypeScript shows you every callsite that needs updating. In large JavaScript codebases, the same change requires grep + manual verification + hoping you didn't miss anything.
Better developer experience
IDE autocompletion, inline documentation, go-to-definition, and automatic import organisation all depend on types. TypeScript makes the development environment significantly more useful.
Industry standard
TypeScript is the default for professional JavaScript development. React, Angular, Vue, NestJS, Next.js — all TypeScript-first. Hiring TypeScript developers is easier than hiring for a team that insists on plain JavaScript.
TypeScript across the full JavaScript ecosystem
TypeScript works everywhere JavaScript works. Here's the ecosystem we use it across.
Common questions about TypeScript development
Is TypeScript worth the overhead for a startup moving fast?
Yes — even for MVPs. The overhead is front-loaded and small. The benefits compound. We've seen TypeScript projects where a junior developer caught a critical bug in code review because TypeScript highlighted an API contract mismatch. That one catch justified the investment for the entire project.
Can you migrate our existing JavaScript codebase to TypeScript?
Yes — we do this incrementally. TypeScript allows mixed JS/TS codebases, so we can migrate file by file, tightening strictness as we go. We start with the highest-risk files (API layers, business logic, shared utilities) rather than doing a big-bang migration.
Do you use strict mode TypeScript?
Yes — strict mode by default. noImplicitAny, strictNullChecks, and the full strict suite enabled from the start. Loose TypeScript often gives false confidence — you still get null pointer errors, just with extra steps. We'd rather deal with the type errors up front.
What tools do you use with TypeScript?
Zod for runtime validation and type inference from schemas. ESLint with TypeScript plugin for code quality. Vitest or Jest for typed tests. tRPC for end-to-end type safety across the API boundary when the stack allows. Prisma for typed database queries. The ecosystem is rich.
