TypeScript for APIs
summary
TypeScript powers definition files (.d.ts) that give JavaScript packages real editor intellisense (VS Code uses them even for plain JS), and community types live in DefinitelyTyped/@types installable from npm (aka.ms/types helps find them). typedoc generates HTML docs from types and comments. OpenAPI/Swagger tooling (swagger-express-mw, nswag) auto-generates client SDKs across languages and server stubs from specs. GraphQL with Apollo generates TypeScript types from schemas and often replaces dozens of REST endpoints with a single typed query surface.
