W kodzie bazowym platformy Node.js w JavaScript wprowadzono zmiany, kt\u00f3re umo\u017cliwiaj\u0105 wykonanie plik\u00f3w z kodem napisanym w j\u0119zyku TypeScript. Obs\u0142uga j\u0119zyka TypeScript jest w\u0142\u0105czana za pomoc\u0105 opcji «—experimental-strip-types» i sprowadza si\u0119 do usuni\u0119cia definicji typ\u00f3w specyficznych dla tego j\u0119zyka, tzn. przekszta\u0142cenia kodu \u017ar\u00f3d\u0142owego do JavaScript przed jego wykonaniem. Funkcje TypeScript niezwi\u0105zane z opisem typ\u00f3w, takie jak przestrzenie nazw, dekoratory, w\u0142a\u015bciwo\u015bci parametr\u00f3w i typy wyliczeniowe (enum), nie s\u0105 na razie wspierane. Now\u0105 funkcjonalno\u015b\u0107 mo\u017cna przetestowa\u0107, korzystaj\u0105c z dzisiejszych nocnych wersji Node.js 23. <\/p>\n

Do translacji u\u017cyty zosta\u0142 kompilator SWC (Speedy Web Compiler), napisany w j\u0119zyku Rust. Aby nie dodawa\u0107 dodatkowych zale\u017cno\u015bci do Node.js, u\u017cyto reprezentacji kompilatora swc\/wasm-typescript, dostarczanej w postaci kodu po\u015bredniego WebAssembly, kt\u00f3ra jest ju\u017c wykorzystywana do tych samych cel\u00f3w w platformie Deno. Zmiana zosta\u0142a dodana w odpowiedzi na liczne pro\u015bby u\u017cytkownik\u00f3w o mo\u017cliwo\u015b\u0107 uruchamiania kodu w TypeScript bez instalacji zewn\u0119trznych loader\u00f3w i dodatkowych zale\u017cno\u015bci. W konkurencyjnych platformach Deno i Bun wsparcie dla TypeScript by\u0142o wprowadzone od samego pocz\u0105tku. <\/p>\n

Kluczow\u0105 r\u00f3\u017cnic\u0105 mi\u0119dzy TypeScript a JavaScript jest jawne okre\u015blenie typ\u00f3w. Statyczna typizacja pozwala unikn\u0105\u0107 wielu b\u0142\u0119d\u00f3w w trakcie rozwoju, umo\u017cliwia stosowanie dodatkowych technik optymalizacji, upraszcza debugowanie oraz sprawia, \u017ce kod staje si\u0119 bardziej czytelny i prostszy do modyfikacji i wsparcia przez zewn\u0119trznych programist\u00f3w. W dodanej do Node.js implementacji te mo\u017cliwo\u015bci TypeScript s\u0105 tracone, poniewa\u017c podczas translacji tekst\u00f3w \u017ar\u00f3d\u0142owych na JavaScript weryfikacja typ\u00f3w nie jest przeprowadzana.
