TypeScript
TypeScript is how we keep growing codebases understandable. It adds explicit contracts to JavaScript, catches whole classes of mistakes before runtime, and makes larger frontend and backend systems easier to change safely.
Why we use it
- /Catches common errors before they reach production
- /Makes interfaces between components and services explicit
- /Improves refactoring confidence as codebases grow
- /Gives teams stronger editor tooling and documentation
When we reach for it
- /Long-lived web applications with growing teams
- /React, Vue, and Node.js products
- /Systems with shared contracts across frontend and backend
- /Codebases where safe refactoring matters
We use TypeScript as a design tool, not just a stricter JavaScript setting. Important boundaries get explicit types: API responses, domain models, component props, events, and shared interfaces between services.
We keep types useful rather than clever. The goal is code another engineer can understand quickly, with the compiler catching mistakes before users do.
Common questions
What is TypeScript used for?+
TypeScript is used to build JavaScript applications with explicit types, helping teams catch mistakes earlier and maintain larger codebases more safely.
Do you use TypeScript for both frontend and backend development?+
Yes. We use TypeScript across frontend applications and Node.js backends where it is a good fit, including shared contracts between the two.
Is TypeScript worth using on smaller projects?+
Often, yes. Even relatively small products can benefit from clearer interfaces and safer refactoring, especially if the product is expected to grow or change hands.
Can you migrate an existing JavaScript project to TypeScript?+
Yes. We usually migrate incrementally, starting with the most important boundaries rather than requiring a full rewrite before development can continue.
Does TypeScript replace testing?+
No. TypeScript catches many structural and type-related mistakes, but it does not verify business logic, user flows, integrations, or runtime behaviour. We use it alongside automated testing.
Can your team work with an existing TypeScript codebase?+
Yes. We can join an existing project, review its type architecture, reduce unsafe patterns, improve maintainability, or simply add engineering capacity within the existing conventions.
