TypeScript First, Always

Every project we deliver uses TypeScript in strict mode. Type safety is not optional — it is how we guarantee fewer bugs and better maintainability.

Technology: TypeScript (Programming Language)

TypeScript is our default language for every JavaScript project — frontend and backend. Its static type system catches bugs at compile time, improves code documentation, and enables powerful IDE tooling. We enforce TypeScript across all React, React Native, and Node.js projects as a non-negotiable quality standard.

What We Build

  • Full-Stack TypeScript Applications: End-to-end type safety from database to UI. Shared types between frontend and backend eliminate an entire class of integration bugs.
  • Type-Safe API Layers: APIs with auto-generated TypeScript clients, runtime validation (Zod), and OpenAPI documentation — all derived from a single source of truth.
  • Large-Scale Refactors: Migrate existing JavaScript codebases to TypeScript incrementally, improving maintainability without halting feature development.

Expertise

  • TypeScript Projects: 300+
  • Average Type Coverage: 95%+
  • Bugs Caught at Compile Time: 40% fewer runtime errors
  • Strict Mode: Always enabled

Sample Projects

  • Monorepo SaaS Platform: Full-stack TypeScript monorepo with shared types between React frontend, Node.js API, and React Native mobile app. (500 hours)
    • Turborepo monorepo with shared packages
    • End-to-end type safety with tRPC
    • Auto-generated API documentation
    • Shared validation schemas (Zod)
  • JavaScript to TypeScript Migration: Incremental migration of a 150K-line JavaScript codebase to strict TypeScript while maintaining feature velocity. (200 hours)
    • File-by-file migration strategy
    • Custom codemods for common patterns
    • Strict mode enforcement from day one
    • Zero production regressions during migration

Frequently Asked Questions

Why does Bookuv.ai require TypeScript?
TypeScript catches 40% of common JavaScript bugs at compile time. It makes code self-documenting, enables powerful refactoring tools, and significantly reduces onboarding time for future developers. It is a non-negotiable quality standard.
Can you convert my existing JavaScript project to TypeScript?
Yes. We specialize in incremental migration strategies that add TypeScript gradually without disrupting ongoing development. Most migrations complete within 2–4 weeks for medium-sized codebases.
Do you use strict mode?
Always. Strict mode is enabled on every project from the start. We also enable additional strict checks like noUncheckedIndexedAccess and exactOptionalPropertyTypes for maximum safety.
