Quick Start

Install the library:

bash

npm install ngxsmk-gatekeeper

Use in your Angular app:

typescript

import { provideGatekeeper, gatekeeperGuard } from 'ngxsmk-gatekeeper';
import { createAuthMiddleware } from 'ngxsmk-gatekeeper';

export const appConfig: ApplicationConfig = {
  providers: [
    provideRouter(routes),
    provideHttpClient(),
    provideGatekeeper({
      middlewares: [createAuthMiddleware()],
      onFail: '/login',
    }),
  ],
};

Protect your routes:

typescript

const routes: Routes = [
  {
    path: 'dashboard',
    component: DashboardComponent,
    canActivate: [gatekeeperGuard],
  },
];

What's New in v1.2.0

Angular 22 / TypeScript 6 Support - Toolchain upgraded to @angular/build@22, ng-packagr@22, and TypeScript 6.0. Tested across Angular 17-22.

Dedicated Testing Entry Point - All test helpers, mock contexts, and assertions now ship via the ngxsmk-gatekeeper/testing secondary entry point for tree-shakeable, test-only imports.

Cache Middleware next Option - createCacheMiddleware can wrap a downstream middleware and cache its allow/deny result (see cacheOnlySuccess).

Expanded Test Coverage - Comprehensive unit tests for the Gatekeeper Agent and core middleware (97+ tests passing).
