QUICK ANSWER

TypeScript engineering at NedDev means strict mode on every codebase, generated types from Prisma or OpenAPI specs, and Zod validation at every trust boundary. From €85 per hour, or fixed-price from €4,500. Type safety delivers 30-40 percent fewer runtime bugs compared with JavaScript-only projects, measurable across our 14+ Next.js production sites.

WHAT FOR

When typescript engineering is the right call.

TypeScript engineering fits when you want to migrate a JavaScript codebase, need end-to-end type safety, or are setting up a monorepo. Built with TypeScript 5, Prisma, Zod, and tRPC.

Use cases

Migration from JavaScript to TypeScript without breaking changes
TypeScript architecture for monorepo projects
End-to-end type safety from database to mobile app
TypeScript coaching and code review for in-house teams

FREQUENTLY ASKED

TypeScript engineering · FAQ.

Why always strict mode?

Strict mode enforces explicit null checks and exact type matching. It delivers 30-40 percent fewer runtime bugs and makes refactoring safe. We treat strict-off as technical debt.

How do you migrate a JavaScript codebase to TypeScript?

Incrementally: .ts files alongside .js, then converting file by file with "any" as a temporary escape, finishing with strict mode on the whole codebase. It takes 2-6 weeks for mid-sized codebases.

What is tRPC and when do you use it?

tRPC gives end-to-end type safety from Next.js frontend to backend without OpenAPI specs or GraphQL overhead. Perfect for monorepo projects where frontend and backend live in the same repo.
