Quickstart

import { MetadataStore } from '@quik/metadata';

function MyDecorator(target: unknown, context: ClassDecoratorContext) {
  const metadata = MetadataStore.get<{ role?: string }>(context.metadata);
  metadata.role = 'admin';
}

Notes​

  • There is no top-level set() method — MetadataStore.get(metadata) lazily creates and returns the stored object for a given DecoratorMetadata key, and callers mutate it directly.
  • MetadataStore.register(metadata, base) initializes metadata with a specific base object the first time it's seen, and is a no-op on subsequent calls for the same key.
  • Metadata is keyed by the native decorator context.metadata object, not by string names — every class using this pattern gets its own isolated metadata record.
  • @quik/metadata is a low-level building block; most application code will not import it directly and instead uses higher-level decorator APIs (e.g. @quik/entity, @quik/http) that are built on top of it.
