ts-ioc-container/esm/metadata/method.js

Fast, lightweight TypeScript dependency injection container with a clean API, scoped lifecycles, decorators, tokens, hooks, lazy injection, customizable providers, and no global container objects.

import { resolveConstructor } from '../utils/basic';
export const addMethodMeta = (key, mapFn) => (target, propertyKey) => {
    const metadata = Reflect.getMetadata(key, target.constructor, propertyKey);
    Reflect.defineMetadata(key, mapFn(metadata), target.constructor, propertyKey);
};
export const getMethodMeta = (key, target, propertyKey) => Reflect.getMetadata(key, resolveConstructor(target), propertyKey);
export const addMethodLabel = (key, label) => addMethodMeta('label', (prev = new Map()) => prev.set(key, label));
export const getMethodLabels = (target, propertyKey) => getMethodMeta('label', target, propertyKey) ?? new Map();
