TypeScript development services
TypeScript is our default for anything that has to survive more than one release. Types are documentation the compiler enforces — which is what makes a codebase safe to hand to the next developer.
Where we use TypeScript
TypeScript is part of the stack on these 4 services. Each page covers how we work, what you get and what it costs to start.
TypeScript in practice
TypeScript adds a type layer over JavaScript that exists only at build time — the shipped code is still JavaScript. What you buy is a compiler that checks the assumptions your code makes about its own data, and editor tooling that turns exploration and renaming into reliable operations rather than careful guesses.
The value shows up disproportionately on codebases that outlive their authors. A typed API contract means a renamed field breaks the build instead of a customer’s screen; a typed component means the next developer sees what it needs without reading its implementation. We enable strict mode from the start, because retrofitting it later is the expensive path.
What we build with TypeScript
Applications where features are added for years and the type system is what stops a refactor from quietly breaking three screens.
Contracts shared between client and server, so a renamed field fails the build instead of failing in production.
Design-system components and utility packages several teams depend on, where a published type signature is the actual interface.
Is TypeScript right for you?
Ask usA good fit when
- Product code you expect to maintain for years
- Teams larger than two, or with any turnover
- Shared contracts between frontend and backend
- Component libraries and packages other teams depend on
Probably not when
- Throwaway prototypes and one-off scripts
- A tiny codebase with one author and a short life
- Teams with no capacity to learn it mid-project under deadline
What we run alongside TypeScript
The rest of the setup, and why each piece is there. We keep this list short on purpose — every dependency is something someone has to maintain.
- strict mode
- The whole point. Without it you get autocomplete but not safety.
- Zod
- Runtime validation that produces types, so external data is checked as well as declared.
- tRPC or OpenAPI codegen
- End-to-end typed API calls, so client and server cannot silently disagree.
- ts-reset
- Fixes some standard library types that are looser than they should be.
Why TypeScript
Let’s talkErrors surface at build time
A whole class of runtime bugs becomes a compiler message, which is the cheapest possible moment to find one.
Editors become useful
Autocomplete, safe rename and go-to-definition work properly, so a new developer explores the codebase instead of guessing at it.
Adoptable in pieces
A JavaScript project can be migrated file by file, so a codebase gets safer without a rewrite you have to justify.
What we get called in to fix
Get a second opinionany everywhere
Types present but disabled in practice. Removing any incrementally is where the actual benefit starts.
Types that lie
Interfaces that no longer match the API, so the compiler cheerfully validates fiction. Runtime validation at the boundary fixes it.
Slow builds
Type checking that takes minutes because of project structure. Usually solvable with project references and incremental builds.
TypeScript or the alternative
The comparisons we are actually asked to make, answered the way we would answer them on a call.
JSDoc is a reasonable route for a library that must ship plain JavaScript. For applications, TypeScript is less friction.
Strict for new projects. Gradual for migrations — file by file, so shipping continues while safety increases.

Frequently asked questions
On a throwaway prototype, often not. On anything you plan to maintain or hand over, the setup cost is repaid within weeks.
Yes, incrementally — strict mode switched on file by file, so the product keeps shipping while the codebase gets safer.
Most often React, Angular and Node. Angular ships TypeScript by default; the others we configure with strict settings from the start.
It never has to be one event. We enable it alongside JavaScript and convert files as they are touched, so there is no freeze.
In the first weeks, slightly. After that it is consistently faster, because refactoring and exploration stop being risky.
