Metadata Introspection

ClaDI exposes helper utilities for reading decorator metadata.

`getInjectableMetadata()`

Read metadata produced by @Injectable(), @Inject(), and lifecycle decorators:

src/injectable-metadata.ts


import { getInjectableMetadata } from "@elsikora/cladi";
 
const metadata = getInjectableMetadata(UserService);
 
console.log(metadata?.token);
console.log(metadata?.lifecycle);
console.log(metadata?.deps);
console.log(metadata?.onInitMethod);
console.log(metadata?.afterResolveMethod);
console.log(metadata?.onDisposeMethod);

`getModuleMetadata()`

Read metadata produced by @Module():

src/module-metadata.ts


import { getModuleMetadata } from "@elsikora/cladi";
 
const moduleMetadata = getModuleMetadata(AppModule);
 
console.log(moduleMetadata?.name);
console.log(moduleMetadata?.imports);
console.log(moduleMetadata?.providers);
console.log(moduleMetadata?.exports);

Common Use Cases

Unit tests that assert decorator wiring
Build-time or startup diagnostics
Tooling that converts class metadata to plain IDIModule definitions
