# RxAngular ![RxAngular CI](https://github.com/rx-angular/rx-angular/workflows/rx-angular%20CI/badge.svg?branch=main)



> RxAngular offers a comprehensive toolkit for handling fully reactive Angular applications with the main focus on runtime performance, template rendering, and Developer eXperience.



## Packages



RxAngular is made up of different packages that work together or standalone.

This repository holds a set of helpers that are aiming to provide:



- fully reactive applications

- fully or partially zone-less applications

- high-performance and non-blocking rendering



## Getting Started



### Using `@rx-angular/template`



This is an example of how to use the `*rxLet` directive to bind an Observable value to the template. In this example, the component defines a property `time$`, which is an Observable that emits a value every second using the `timer` operator. The emitted values are mapped to the current time string using the `map` operator which is then displayed in the template using `*rxLet`.



```ts

import { RxLet } from '@rx-angular/template/let';



@Component({

  selector: 'app-time',

  standalone: true,

  imports: [RxLet],

  template: `

    

      {{ value }}

    

  `,

})

export class TimeComponent {

  time$ = timer(0, 1000).pipe(map(() => new Date().toTimeString()));

}

```

### Using `@rx-angular/state`



In this example, we're creating a fully reactive counter component. We use `rxState` to manage the component's state, `rxActions` to define structured actions for state updates (specifically `increment` and `decrement`), and `rxEffects` to trigger side-effects when state changes occur. These mechanisms collectively enable efficient state management, action handling, and side-effect execution, resulting in a responsive and well-structured counter component.



```ts

import { rxState } from '@rx-angular/state';

import { rxEffects } from '@rx-angular/state/effects';

import { rxActions } from '@rx-angular/state/actions';

import { RxPush } from '@rx-angular/template/push';



@Component({

  selector: 'app-counter',

  standalone: true,

  imports: [RxPush],

  template: `

    
Count: {{ count$ | push }}


    Increment

    Decrement

  `,

})

export class CounterComponent {

  readonly actions = rxActions<{

    increment: void;

    decrement: void;

  }>();



  private readonly state = rxState<{

    count: number;

  }>(({ set, connect }) => {

    set({ count: 0 });

    connect(this.actions.increment$, (state) => ({

      count: state.count + 1,

    }));

    connect(this.actions.decrement$, (state) => ({

      count: state.count - 1,

    }));

  });



  readonly count$ = this.state.select('count');



  constructor() {

    rxEffects(({ register }) => {

      register(this.count$, (count) => console.log(`Count changed: ${count}`));

    });

  }

}

```
