Nano Stores Angular

Angular integration for Nano Stores, a tiny state manager with many atomic tree-shakable stores.

How to install

pnpm add @nanostores/angular # or npm or yarn

How to use

// your NgModule:
import { NANOSTORES, NanostoresService } from '@nanostores/angular';

@NgModule({ providers: [{ provide: NANOSTORES, useClass: NanostoresService }], ... })

app.component.ts:

// example using async pipes:
import { Component } from '@angular/core';
import { NanostoresService } from '@nanostores/angular';
import { Observable, switchMap } from 'rxjs';

import { profile } from '../stores/profile';
import { IUser, User } from '../stores/user';

@Component({
  selector: "app-root",
  template: '<p *ngIf="(currentUser$ | async) as user">{{ user.name }}</p>'
})
export class AppComponent {
  currentUser$: Observable<IUser> = this.nanostores.useStore(profile)
    .pipe(switchMap(userId => this.nanostores.useStore(User(userId))));

  constructor(private nanostores: NanostoresService) { }
}

// example without async pipes:
import { Component, OnInit } from '@angular/core';
import { NanostoresService } from '@nanostores/angular';
import { switchMap } from 'rxjs';

import { profile } from '../stores/profile';
import { User } from '../stores/user';

@Component({
  selector: "app-root",
  template: '<p>{{ text }}</p>'
})
export class AppComponent implements OnInit {
  text = '';

  constructor(private nanostores: NanostoresService) { }

  ngOnInit() {
    this.nanostores.useStore(profile).pipe(
      switchMap((userId: string) => this.nanostores.useStore(User(userId)))
    )
    .subscribe(user => this.text = `User name is ${user.name}`);
  }
}
