NgRx Signal Store vs Classic NgRx in 2026: Which Should You Choose?
A comprehensive comparison of NgRx Signal Store and Classic NgRx for Angular state management. Learn when to use each approach with practical code examples.
Angular
FRONTEND
Comprehensive frontend framework developed by Google with TypeScript as primary language. Component-based modular architecture, native Dependency Injection, RxJS for reactive programming and robust CLI to build scalable and maintainable web applications.
What you'll learn
Strict TypeScript with decorators and advanced types (@Component, @Injectable)
Modular architecture with NgModules and lazy loading
Hierarchical Dependency Injection with providers and scopes
RxJS for reactive programming (Observables, Operators, Subjects)
Powerful template syntax (data binding, directives, pipes)
Robust forms (Template-driven and Reactive Forms with validation)
Advanced Router with guards, resolvers, lazy loading and preloading
HttpClient with interceptors, caching and error handling
Signals for reactive state management (Angular 16+)
Comprehensive testing (Jasmine, Karma, TestBed, mocking, E2E with Cypress)
Key topics to master
The most important concepts to understand this technology and ace your interviews
1
TypeScript: decorators, advanced types, interfaces, generics
2
Components: templates, styles, lifecycle hooks, ViewChild, ContentChild
3
Data binding: interpolation, property binding, event binding, two-way binding
4
Directives: structural (*ngIf, *ngFor, *ngSwitch), attribute (ngClass, ngStyle), custom
5
Pipes: built-in (date, async, json), custom pipes, pure vs impure
6
Services and Dependency Injection: providers, hierarchical DI, injection tokens
7
RxJS: Observables, Operators (map, filter, switchMap, mergeMap), Subjects, unsubscribe
8
Forms: Template-driven vs Reactive, FormControl, FormGroup, validators, async validators
9
Routing: routes, RouterLink, RouterOutlet, guards (CanActivate, CanDeactivate), resolvers
10
HttpClient: GET/POST/PUT/DELETE, interceptors, error handling, retry logic
11
Change Detection: strategies (Default, OnPush), zones, manual triggering
12
NgModules: imports, exports, declarations, providers, lazy loading
13
Signals: signal(), computed(), effect(), reactive state (Angular 16+)
14
State management: Services with BehaviorSubject, NgRx (Store, Effects, Selectors)
15
Testing: unit tests (Jasmine, TestBed), component testing, service mocking, E2E
16
Performance: OnPush, trackBy, lazy loading, preloading strategies, bundle optimization
17
Angular CLI, build configuration, deployment, SSR with Angular Universal
