TYPESCRIPT
Strongly Typed Code for Reliable, Scalable Products
FrontIT delivers typescript development services that help European and European businesses ship reliable software faster. With over two decades of hands-on engineering and a team of 70+ specialists in Vilnius, we use TypeScript’s strong typing system to catch bugs early, simplify refactoring, and keep large codebases maintainable. Whether you are launching a new product or modernising a legacy platform, our approach combines proven architecture patterns with the practical benefits of static analysis, so your project stays on track from the first sprint to the final release.
WHY TYPESCRIPT
01
JavaScript powers most of the modern web, but as applications grow, untyped code becomes a liability. TypeScript adds a compile-time type layer that reveals mismatches before they reach production. For teams working on enterprise typescript development projects with dozens of modules and hundreds of endpoints, that early feedback loop saves significant time and money.
02
Auto-complete, inline documentation, and safe refactoring tools all become dramatically better when the editor understands your types. This is one reason why typescript application development has seen such rapid adoption across the industry. Developers spend less time reading code and more time writing features.
03
Codebases live for years. Teams rotate. Requirements shift. TypeScript acts as living documentation, making it far easier for new engineers to understand contracts between components. That clarity is a core part of every typescript engineering services engagement we take on.
WHAT WE BUILD
01
Rich, interactive frontends built with React, Angular, or Vue and powered by TypeScript. Our typescript frontend development work covers everything from design-system integration to complex state management, resulting in apps that feel fast and stay robust as features accumulate.
02
Using frameworks like NestJS and Next.js alongside TypeScript on both client and server, we build end-to-end platforms with shared type definitions. This is where custom typescript development truly shines, because a single type change propagates through the entire stack and the compiler flags every spot that needs updating.
03
We design strongly typed REST and GraphQL APIs that are easy to consume and hard to misuse. Our typescript software development practice emphasises contract-first design, meaning frontend and backend teams can work in parallel with confidence that the integration will be smooth.
04
When your product needs a public or internal SDK, TypeScript is an excellent choice. Type declarations serve as built-in docs, and consumers get instant feedback in their editors. Our typescript coding services include publishing, versioning, and maintaining packages that other teams depend on daily.
EXPERTISE
01
We enable strict mode from day one and pair it with ESLint rules tailored to your project. This is a hallmark of our work as a typescript development company: we believe that investing in tooling upfront pays dividends throughout the product lifecycle.
02
For organisations running multiple apps and shared libraries, we set up monorepo toolchains with Nx or Turborepo. Scalable typescript solutions require thoughtful project boundaries and dependency graphs, and our engineers know how to structure them so builds stay fast even as the repo grows.
03
Type safety does not mean slow. We profile compilation times, tune incremental builds, and structure imports to keep the developer experience snappy. When you hire typescript developers from FrontIT, you get a team that treats build performance as a first-class concern, not an afterthought.
04
TypeScript pairs naturally with testing frameworks like Jest and Vitest. We write unit, integration, and end-to-end tests that leverage type information to generate better coverage. Our custom typescript solutions include CI pipelines that run type checks, linting, and tests on every pull request.
INTEGRATION & MIGRATION
01
Rewriting an entire codebase overnight is rarely practical. We take an incremental approach, converting files module by module while keeping the application fully functional. Our typescript web development services include migration roadmaps that balance speed with risk, so your team can adopt TypeScript without halting feature delivery.
02
Most projects rely on external APIs, payment gateways, or legacy systems. We create typed wrappers and adapters that make these integrations safe and predictable. As a dedicated typescript development agency, we have handled connections to ERP platforms, CRM tools, and cloud services across a wide range of industries.
WHY FRONTIT
01
We have been building software since 2006. That experience means we understand not just the technology but also the business context behind it. Clients across Denmark, Sweden, and the wider EU trust us because we communicate clearly and we deliver on our commitments.
02
Every engagement starts with a discovery phase where we align on goals, timelines, and technical approach. Throughout the project we share progress in weekly demos and keep all code in your repository. You own everything we produce, no strings attached.
SUPPORT
01
Launching is just the beginning. We offer long-term support agreements that cover dependency upgrades, performance monitoring, and feature enhancements. Think of it as a partnership, not a handoff. Our team stays close to your codebase so we can respond quickly when priorities change or new opportunities arise.
