Large React applications
Typed API clients, forms and state for products with many screens and several developers working at once.
TypeScript development
TypeScript for front ends that have to stay maintainable.
On larger front ends we write TypeScript, so changes are checked before they reach users. It runs the React 18 and Ant Design front end of the EM2 event platform, and the Lit web components of Auto.co.il, a major Israeli car portal rebuilt on Umbraco 15.

What we build with TypeScript
Where TypeScript earns its place.
The kinds of work we use TypeScript for, based on the projects below rather than a list of everything the technology can do.
Web components
Lit components in TypeScript that work inside any CMS template and stay light on the page.
Typed contracts with the back end
Shared types between front end and API, so a renamed field breaks the build, not production.

TypeScript FAQ
TypeScript questions we hear.
Anything missing? Send us your question and an engineer will answer, usually within one business day.
Contact usDo you write new front ends in TypeScript?+
Yes, for anything beyond a small script. It costs little extra time and saves a lot when the code changes later.
Can you add TypeScript to an existing JavaScript project?+
Yes, gradually: new files in TypeScript first, then the most-changed modules, without stopping feature work.
What are Lit web components?+
Small standard components that run in any page without a framework. On Auto.co.il we used Lit with TypeScript for front-end components inside an Umbraco site.
