TypeScript Development Services
TypeScript is JavaScript with types, catching errors before code runs and making large codebases easier to maintain. We use TypeScript across front ends, Node.js back ends and full-stack projects, and help teams migrate existing JavaScript.
TypeScript adds types to JavaScript, which catches mistakes before code runs and makes large codebases far easier to change safely. We use TypeScript by default on React, Next.js, Angular and Node.js projects, and we help teams migrate existing JavaScript.
Why choose TypeScript
- Catches many bugs at build time rather than in production.
- Better editor support and safer refactoring.
- Works across React, Angular, Vue, Next.js and Node.js.
What we build with TypeScript
- Large front-end applications
- Node.js APIs and services
- Shared types between front end and back end
- Migrating JavaScript codebases

How we migrate JavaScript to TypeScript
Set up
add TypeScript alongside existing JavaScript, with no big-bang rewrite.
Convert gradually
start with shared utilities and API types, then screens and services.
Tighten
increase strictness step by step as coverage grows.
Automate
type checks in CI so new code stays typed.

Frequently asked questions
For growing or long-lived codebases, usually yes. Migration can be done gradually, file by file.
Slightly at first, but it usually saves time overall through fewer bugs and safer changes.
Yes. We start with a code review, fix urgent issues and continue development or support.
Yes. TypeScript and JavaScript can live side by side, so we convert files gradually without stopping feature work.
Yes. We build Node.js back ends in TypeScript with NestJS or Express and share types with the front end.
