TypeScript engineering
We write the front end in TypeScript with React and Next.js, for web apps that stay safe to change as they grow.
Catch mistakes before your users do
TypeScript checks your code as you write it, so a whole class of bugs, typos, wrong shapes, missing cases, is caught before anything ships. That means fewer runtime surprises and more confidence when you change things. For a product that needs to keep evolving, that safety net is the difference between moving fast and breaking things.
- Errors caught at build time
- Fewer runtime surprises
- Confident refactoring
One language across the stack
We use TypeScript on the front end with React and Next.js, and share types with the API where it makes sense, so the contract between client and server is enforced by the compiler. That cuts the integration bugs that come from the two sides drifting apart, and makes the whole codebase easier to navigate.
- React and Next.js in TypeScript
- Shared client and server contracts
- Fewer integration bugs
Code the next engineer can read
Types are documentation that cannot go out of date. A well-typed codebase tells a new engineer what a function expects and returns without digging through the implementation. We keep types meaningful rather than scattering "any" everywhere, so the safety is real and the code stays approachable as the team grows.
- Types as living documentation
- Meaningful types, not "any"
- Approachable for new engineers
Adopt it gradually, no big rewrite
You do not need to stop everything to adopt TypeScript. We migrate existing JavaScript incrementally, file by file, fixing types as we go while the product keeps shipping. New code is written in TypeScript from the start. That way you get the benefits steadily without a risky all-at-once rewrite.
- Incremental migration from JavaScript
- Product keeps shipping
- New code typed from the start
Part of the wider stack
TypeScript pairs with our Next.js front ends and typed Python APIs. Building a product? See MVP development for startups.
TypeScript questions
TypeScript catches a whole class of bugs at build time, makes refactoring safe, and acts as living documentation. For products that need to keep changing, that safety net lets you move quickly without breaking things.
Yes, gradually. We convert files incrementally and fix types as we go while the product keeps shipping, rather than attempting a risky big-bang rewrite.
On the front end always, and we share types with the API where it helps. Our Python backends use type hints for similar safety, so the whole stack stays well-typed.
