TypeScript development at ZeroPixel
TypeScript is JavaScript with a safety net: a type system that catches whole categories of bugs while the code is being written instead of when a customer hits them. It's now the standard for serious web software — Microsoft, Stripe, and Shopify run on it — and it's the only way ZeroPixel writes code.
For a business buying software, the type system is invisible but its effects aren't. TypeScript codebases have measurably fewer production defects, survive team changes better, and are dramatically cheaper to extend — because the compiler documents how everything fits together and refuses to let a change quietly break something three files away.
We build full-stack TypeScript: React and Next.js frontends, Node.js APIs, database layers and integrations, all sharing one type system end to end. When the API changes, the frontend knows at compile time — not in production on a Friday evening. We also convert existing JavaScript codebases to TypeScript incrementally, without stopping feature work.
What we build in TypeScript
One language across the whole stack — these are the four shapes that benefit most from end-to-end types.
Full-stack applications
Frontend, API and database contracts in one typed system — a change anywhere is checked everywhere, automatically.
APIs & integrations
Typed REST and GraphQL APIs, and integrations with CRMs, payment providers and third-party platforms that fail loudly in development instead of silently in production.
JavaScript → TypeScript
Incremental conversion of existing codebases — strictness ratchets up file by file while your product keeps shipping.
Shared libraries & SDKs
Internal packages and public SDKs with types as documentation — so other teams integrate correctly on the first try.
Why hire ZeroPixel for TypeScript work
- Strict, not decorative
- Plenty of codebases 'use TypeScript' with strict mode off and any everywhere — which buys nothing. We write strict TypeScript where the types actually model the business domain, which is where the defect prevention comes from.
- Types as the contract
- Shared types between frontend and backend mean the two can't drift apart. Entire classes of integration bugs — the expensive, hard-to-reproduce kind — simply stop existing.
- Built for the next team
- A well-typed codebase is self-documenting: any competent developer can open it and see how data flows. That's deliberate — we build assets you own, not dependencies on us.
TypeScript — common questions
Why does TypeScript matter to me as a business owner?
Fewer bugs, cheaper changes, and less key-person risk. The compiler catches mistakes before deployment, refuses changes that would break other parts of the system, and documents how the code fits together — so a new developer becomes productive in days rather than months. You experience it as software that breaks less and evolves faster.
Can you convert our existing JavaScript project to TypeScript?
Yes, and it doesn't require a freeze. TypeScript is designed for incremental adoption: we convert module by module, starting where bugs hurt most, while your team keeps shipping features. Most conversions pay for themselves through the bugs they surface during the migration itself.
Is TypeScript slower to build with?
Slightly slower to type the first line, significantly faster to reach working software. The time saved on debugging, regressions and code review outweighs the annotation cost within weeks — which is why nearly every major product company has standardised on it. On fixed-quote projects, that maths is our problem anyway, and we still choose TypeScript every time.
Do you write tests as well?
Yes — types and tests catch different things, and serious codebases need both. Types eliminate structural bugs; tests cover business logic and critical flows like payments and authentication. We aim tests where failure is expensive rather than chasing coverage numbers for their own sake.
What stack do you pair TypeScript with?
React and Next.js on the frontend; Node.js on the backend; PostgreSQL, Supabase or Convex for data, depending on the shape of the product. One language across all of it keeps the codebase coherent and your future hiring simple — TypeScript developers are the largest talent pool in web development.
Beyond TypeScript
A stack is a set of choices that have to work together — these are the pieces we most often pair with TypeScript, and where we do it.
