@esfx/metadata-shim
The @esfx/metadata-shim package is a global shim that adds minimal @esfx/metadata functionality to the Reflect global object.
This provides partial compatibility with TypeScript's --emitDecoratorMetadata flag.
Overview
Installation
npm i @esfx/metadata-shimUsage

return "";
}
}
const c = new MyClass();
getMemberMetadata(c, "method", "design:returntype"); // String
getMemberMetadata(c, "method", "design:paramtypes"); // [Number]API
