Typed engineering at any scale

TypeScript Development

TypeScript is used across WLC's React/Next.js frontends and Node.js (NestJS) backends. It gives teams better tooling, safer refactoring and cleaner collaboration on complex applications.

What this type of engagement typically covers.

  • TypeScript everywhere
  • Typed APIs
  • Frontend & backend
  • Maintainable code
Why WLC

Built for buyers who need clarity, speed and accountability.

Three principles that shape how we scope, build and deliver every engagement.

01

Share types between frontend and backend, reducing a common class of integration bugs before they reach QA.

02

Refactor confidently on larger codebases, since the compiler catches type mismatches immediately.

03

Onboard new engineers faster with self-documenting function signatures and data shapes.

04

Catch null/undefined errors and API contract mismatches at compile time instead of in production.

05

Improve editor tooling—autocomplete, inline documentation, safe renames—across the whole codebase.

06

Migrate an existing JavaScript codebase to TypeScript incrementally, file by file, without a disruptive full rewrite.

Questions buyers ask

Common questions before starting a project.

TypeScript is used by default across our React/Next.js frontend work and Node.js/NestJS backend work. The six core technologies are React.js, Node.js, Python, React Native, Claude and OpenAI.

Yes—we typically migrate incrementally, adding types file by file starting with the highest-risk or most-changed parts of the codebase, rather than a disruptive big-bang conversion.

There's a small upfront cost to writing types, but it's consistently offset by fewer runtime bugs, faster refactors and less time spent debugging integration mismatches on any codebase beyond a small prototype.

Yes—our Node.js/NestJS backends are written in TypeScript, which lets us share type definitions with the frontend and catch API contract mismatches at build time.

Core stack — interactive frontend applications

React.js Development

React and Next.js are part of WLC's core engineering stack. We use them to build interactive UIs, dashboards, portals and customer-facing products with reusable, typed components rather than one-off page templates.

Core stack — scalable backend applications

Node.js Development

Node.js, typically with the NestJS framework, is part of WLC's core backend stack. We use it to build APIs, microservices, real-time systems and integration-heavy platforms that need to handle high I/O concurrency reliably.
