<div class="alert-is-helpful">
The decorator requirement is imposed by TypeScript. TypeScript normally discards parameter type information when it [transpiles]((guide/glossary#transpile) the code to JavaScript. TypeScript preserves this information if the class has a decorator and the `emitDecoratorMetadata` compiler option is set `true` in TypeScript's `tsconfig.json` configuration file. The CLI configures `tsconfig.json` with `emitDecoratorMetadata: true`.
