ts-ioc-container/esm/hooks/onConstruct.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 { hook } from './hook';
import { HooksRunner } from './HooksRunner';
export const onConstructHooksRunner = new HooksRunner('onConstruct');
export const onConstruct = (...fns) => hook('onConstruct', ...fns);
export class AddOnConstructHookModule {
    onException;
    constructor(onException) {
        this.onException = onException;
    }
    applyTo(container) {
        container.addOnConstructHook((instance, scope) => {
            try {
                onConstructHooksRunner.execute(instance, { scope });
            }
            catch (ex) {
                if (!this.onException) {
                    throw ex;
                }
                this.onException(ex, { scope });
            }
        });
    }
}
