Why TypeScript matters for your frontend
TypeScript catches bugs at compile time, not runtime. Every IRPR project uses strict TypeScript with no implicit any.
TypeScript reduces production bugs by up to 40% compared to plain JavaScript. Our team enforces strict mode, noImplicitAny, and strictNullChecks. We use ESLint with @typescript-eslint rules to enforce consistent types across every file.
For a fintech client, we migrated 150,000 lines of JavaScript to TypeScript in 10 weeks. The client reported zero runtime type errors after launch. TypeScript also improved developer onboarding time by 50% because new engineers could read type definitions.
Generic dev shop vs a TypeScript specialist agency
Not all agencies treat TypeScript as a first-class requirement. Here is the difference.
Many dev shops write JavaScript first and add types later. They skip strict mode, use any, and ignore generics. This leads to runtime errors and slow refactoring.
IRPR writes TypeScript from the first line of code. We set strict mode, use union types, generics, and branded types. Every pull request runs TypeScript compilation as a CI gate.
- Starts with JavaScript, adds types later
- Allows implicit any in codebase
- No type coverage enforcement
- Uses outdated TypeScript 3.x configs
- No CI gate for type errors
- Mixed JS and TS files in same project
- Writes TypeScript from line one
- Strict mode with noImplicitAny
- 100% type coverage on all modules
- Uses TypeScript 5.x with latest features
- TypeScript compilation fails CI on any error
- Pure TypeScript codebase, no JS files
Our process for TypeScript frontend projects
We follow a 4-phase process that starts with a fixed-price Roadmap phase.
Every project begins with a 2-week Roadmap phase. We define TypeScript types for every data model, API endpoint, and component. You get a fixed price quote at the end of Roadmap.
The Product phase builds the frontend in 8-12 weeks. We ship in 2-week sprints with demoable features. Every sprint ends with a TypeScript type check and unit test pass.
What you get with every TypeScript frontend project
Every project ships with a standard set of deliverables. No hidden fees or missing pieces.
We include everything needed to run, maintain, and scale your TypeScript frontend. All code is in your repository from day one.
- Full TypeScript source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions with TypeScript compilation
- Sentry error tracking with TypeScript source maps
- Unit tests with Jest and React Testing Library (typed)
- Storybook component library with TypeScript prop tables
- Vercel or AWS deployment configuration
- TypeScript ESLint configuration with strict rules
- TypeScript API client generated from OpenAPI spec
- Performance budget with Lighthouse CI
- Documentation for every typed component and utility
What we ship in this practice.
SaaS analytics dashboard with TypeScript
Built a real-time analytics dashboard for a B2B SaaS company using Next.js, TypeScript, and Recharts. TypeScript types for every metric and filter reduced data processing bugs by 60%. The client reported 40% faster load times with ISR.
Fintech trading platform frontend
Developed a trading UI with React, TypeScript, and WebSockets. TypeScript branded types for order IDs and currency amounts prevented accidental misuse. The platform handles 10,000 concurrent users with 99.9% uptime.
HIPAA-compliant patient portal
Built a patient portal with Next.js, TypeScript, and AWS Cognito. TypeScript types for PHI fields and role-based access controls passed HIPAA audit. The client reduced patient data entry errors by 80%.
Ecommerce checkout with Stripe
Created a headless ecommerce frontend using Next.js, TypeScript, and Stripe. TypeScript union types for payment status and order state prevented invalid transitions. The client saw a 25% increase in checkout conversion.
EdTech learning management system
Developed an LMS frontend with Vue 3, TypeScript, and Pinia. TypeScript generics for course content types made adding new lesson formats easy. The platform supports 50,000 students with FERPA compliance.
Real estate MLS search interface
Built a property search UI with React, TypeScript, and Mapbox. TypeScript discriminated unions for property types and listing statuses eliminated invalid filters. The client reduced search result errors by 90%.
