Top Angular State Management Libraries

ngrx/platform is a comprehensive set of libraries for building reactive applications using the Angular framework.

Code Example

import { NgModule } from '@angular/core';
import { StoreModule } from '@ngrx/store';
import { counterReducer } from './counter.reducer';

@NgModule({
  imports: [
    StoreModule.forRoot({ count: counterReducer })
  ]
})
export class AppModule {}

Pros

1. Comprehensive Ecosystem: ngrx/platform provides a wide range of libraries, including state management, effects, selectors, and more, making it a complete solution for building reactive Angular applications.
2. Reactive Approach: ngrx/platform follows the principles of reactive programming, which can lead to more maintainable and scalable applications.
3. Familiarity for Angular Developers: ngrx/platform is designed specifically for the Angular ecosystem, making it a natural choice for Angular developers.

Cons

1. Steep Learning Curve: ngrx/platform can have a steeper learning curve compared to some other state management solutions, especially for developers new to reactive programming.
2. Boilerplate Code: ngrx/platform can require more boilerplate code compared to some other state management solutions, which can make it less appealing for smaller projects.
3. Performance Overhead: ngrx/platform's comprehensive feature set can come with some performance overhead, which may be a concern for certain types of applications.

ngrx/store is a state management library for Angular applications, inspired by Redux.

Code Example

import { createReducer, on } from '@ngrx/store';
import { increment, decrement, reset } from './counter.actions';

const initialState = 0;

const counterReducer = createReducer(
  initialState,
  on(increment, (state) => state + 1),
  on(decrement, (state) => state - 1),
  on(reset, (state) => 0)
);

Pros of ngrx/store

1. Provides a predictable state management pattern, making it easier to manage complex application state.
2. Integrates well with the Angular ecosystem, providing a seamless experience for Angular developers.
3. Offers a rich ecosystem of related libraries, such as ngrx/effects and ngrx/router-store, for handling side effects and routing.

Cons of ngrx/store

1. Steeper learning curve compared to some other state management solutions, especially for developers new to the Redux pattern.
2. Increased boilerplate code, as it requires the creation of actions, reducers, and selectors.
3. Potential performance issues if not implemented correctly, as the immutable nature of the state can lead to unnecessary re-renders.

Other Projects

ngrx/platform

ngrx/platform is a collection of libraries that provide a comprehensive state management solution for Angular applications, including ngrx/store.

salesforce/akita

Akita is a state management pattern, built with RxJS, that takes the idea of multiple data stores from Flux and the immutable updates from Redux, along with the concept of streaming data, to create the Observable Data Source model.

TanStack/form

TanStack/form is a powerful, flexible, and extensible forms library for React, Vue, and Angular, providing a declarative and reactive approach to form management.

ngxs/store

NGXS is a state management pattern and library for Angular. It uses a simple and elegant API to let you manage the state of your application using class-based state containers.

storeon/storeon

Storeon is a tiny (167 bytes) event-emitter state manager for React, Preact, Angular, Vue, and Svelte. It provides a simple and lightweight alternative to more complex state management solutions.

Akita is a state management pattern, built on top of RxJS, which takes the idea of multiple data stores from Flux and the immutable updates from Redux, along with the concept of "Smart Components" from NgRx.

Code Example

import { EntityState, EntityStore, StoreConfig } from '@datorama/akita';

interface User {
  id: string;
  name: string;
}

@StoreConfig({ name: 'users' })
export class UsersStore extends EntityStore<EntityState<User>> {
  constructor() {
    super();
  }
}

Pros of Akita

1. Simplicity: Akita provides a more straightforward and less boilerplate-heavy approach to state management compared to some other libraries.
2. Performance: Akita's focus on performance and optimization can lead to faster application performance.
3. Flexibility: Akita's modular design allows for easy integration with various frameworks and libraries.

Cons of Akita

1. Smaller Community: Akita has a smaller community compared to some other popular state management libraries, which may mean fewer resources and support available.
2. Learning Curve: While simpler than some alternatives, Akita still requires developers to understand its concepts and patterns, which can have a learning curve.
3. Vendor Lock-in: Akita is primarily developed and maintained by Salesforce, which could be a concern for some developers who prefer more vendor-neutral solutions.

TanStack/form is a powerful and flexible form management library for React.

import { useForm } from '@tanstack/react-form';

const { register, handleSubmit } = useForm();

Pros of TanStack/form

1. Flexibility: TanStack/form offers a highly customizable and extensible API, allowing developers to tailor the form management to their specific needs.
2. Performance: The library is designed with performance in mind, minimizing unnecessary re-renders and providing efficient state management.
3. Validation: TanStack/form includes a robust validation system, making it easy to implement complex validation rules.

Cons of TanStack/form

1. Learning Curve: The library's flexibility and power may come with a steeper learning curve compared to some simpler form management solutions.
2. Ecosystem: TanStack/form may have a smaller ecosystem and community compared to some of the more established state management libraries like ngrx/store or ngxs/store.
3. TypeScript Support: While TanStack/form does provide TypeScript support, the type definitions may not be as comprehensive as some other TypeScript-focused libraries.

ngrx/platform, ngrx/store, salesforce/akita, ngxs/store, storeon/storeon

These projects are primarily state management libraries, with a focus on managing the overall application state, rather than specifically handling form management. They offer different approaches and features for state management, but do not directly compete with the specialized functionality of TanStack/form.

ngxs/store is a state management pattern and library for Angular applications.

@State<TodoStateModel>({
  name: 'todos',
  defaults: {
    todos: []
  }
})
export class TodosState {
  @Selector()
  static getTodos(state: TodoStateModel) {
    return state.todos;
  }
}

Pros of ngxs/store

1. Simplicity: ngxs/store provides a simpler and more concise syntax compared to ngrx/store, making it easier to set up and maintain.
2. Reactive Approach: ngxs/store follows a reactive approach, which can lead to better performance and easier state management.
3. Dependency Injection: ngxs/store integrates well with Angular's dependency injection system, making it easier to manage dependencies.

Cons of ngxs/store

1. Smaller Community: Compared to ngrx/store, ngxs/store has a smaller community and fewer resources available.
2. Maturity: ngrx/store has been around for longer and has a more established ecosystem, which can be an advantage for some projects.
3. Compatibility: ngxs/store may have compatibility issues with some third-party libraries that are designed to work with ngrx/store.
