TypeScript

The default for serious JavaScript development. Its structural type system catches bugs at compile time while remaining compatible with the full JavaScript ecosystem.

Where it fits

Type safety from database to browser

TypeScript goes beyond basic annotations. Mapped types, conditional types, and template literal types enable type-level programming. You can derive API response types from database schemas and validate route parameters at compile time.

Tools like Zod, tRPC, and Drizzle ORM make type boundaries automatic. The real value emerges in full-stack applications where types flow end to end.

What we deliver

Our TypeScript capabilities

01

End-to-end type inference

API types flow from server to client without code generation. A single Zod schema produces types, validation, and form rules.

tRPCZodOpenAPI
02

Advanced type-level patterns

Discriminated unions for state machines, branded types for IDs, and const assertions for literal types.

03

Monorepo & shared packages

Turborepo or Nx monorepos sharing types, validation, and utilities across front-end, back-end, and mobile.

Why Adaca

Why Adaca for TypeScript?

Strict TypeScript standards

strict mode, noUncheckedIndexedAccess, and exactOptionalPropertyTypes. We catch bugs that default tsconfig misses.

Full-stack type sharing

Types flow from Drizzle or Prisma schemas through tRPC to React components. One source of truth.

JS-to-TypeScript migration

Incremental migration from allowJs and strict: false, progressively tightening to full strict mode.

Toolchain configuration

ESLint with typescript-eslint, Prettier, Vitest, and build pipelines optimised for fast feedback.

Library & SDK development

Typed SDKs and component libraries with .d.ts declarations, source maps, and dual ESM/CJS output.

Type-safe API contracts

OpenAPI specs generated from Zod schemas or tRPC routers. API changes become compile errors, not runtime surprises.
