Why choose a TypeScript app development firm
TypeScript catches errors at compile time, not in production.
TypeScript reduces runtime errors by up to 40% compared to plain JavaScript. Our firm uses strict TypeScript configs with noImplicitAny and strictNullChecks enabled. Every PR runs ESLint and Prettier checks in CI.
We build with Next.js 14 for server-side rendering, Node.js 20 for APIs, and React 18 for UIs. All code is fully typed, including database queries with Prisma and API responses with Zod validation.
Generic dev shop vs TypeScript app development firm
Not all shops deliver production-grade TypeScript. Here is the difference.
Generic shops often use anyType and skip strict mode. They deliver code that compiles but fails at runtime. They do not enforce code reviews or automated testing.
IRPR treats TypeScript as a reliability tool. We enforce strict types, write unit tests with Jest, and run end-to-end tests with Playwright. Every app ships with a typed API layer and error boundaries.
- Uses anyType and loose configs
- No automated testing in CI
- No Sentry error tracking by default
- No CI/CD pipeline included
- Hourly billing with no fixed scope
- No post-launch support plan
- Strict TypeScript with noImplicitAny
- Jest unit tests + Playwright E2E tests
- Sentry error tracking on day one
- CI/CD on GitHub Actions with auto-deploy
- Fixed price from Roadmap phase
- 2 weeks of post-launch support included
How we build your TypeScript app in 12 weeks
Four phases, fixed timeline, no scope creep.
We use a structured process that starts with a Roadmap document. You get a clear scope, timeline, and fixed price before any code is written. No surprises.
Each phase ends with a working demo. You see progress every 2 weeks. The final release includes source code, documentation, and a production-ready deployment.
What ships with every TypeScript app
Every project includes production essentials, not just code.
We do not hand over a zip file. You get a fully operational system with monitoring, logging, and deployment pipelines. Your team can start contributing on day one.
All code is owned by you. No licensing fees, no lock-in. You can deploy to any cloud provider or on-premise.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking and performance monitoring
- Automated tests with Jest and Playwright
- Dockerized development environment
- API documentation with Swagger or GraphQL schema
- Deployment scripts for AWS or Vercel
- User authentication with Auth0 or NextAuth.js
- Database migrations with Prisma
- Post-launch support for 2 weeks
