Managing tasks efficiently is critical for productivity, whether you’re handling a personal to-do list or managing complex workflows in a large organization. Traditional state management solutions in Angular, such as NgRx, offer powerful tools but often come with significant boilerplate code and complexity. Enter @ngrx/signalstore, a modern, signal-based state management library designed to simplify and optimize application state. In this deep dive, we’ll explore how the power of @ngrx/signalstore: a deep dive into task management can revolutionize the way you build task management applications.
What is @ngrx/signalstore?
@ngrx/signalstore is a state management library that brings fine-grained reactivity to Angular applications. Unlike traditional NgRx, which relies heavily on Actions, Reducers, and Effects, SignalStore simplifies state management by using signals—reactive values that automatically update when their dependencies change.
This means:
✅ Less boilerplate – No need to define complex reducers and effects.
✅ Better performance – Signals update only the necessary parts of the UI.
✅ Easier debugging – The state is easier to track and modify.
✅ Improved reactivity – Updates happen instantly without extra subscriptions.
For task management applications, where users frequently add, update, and remove tasks, these advantages translate into faster UI updates, cleaner code, and an overall better development experience.

Why Use @ngrx/signalstore for Task Management?
Task management applications typically involve handling complex states, including:
🔹 Task lists with multiple statuses (Pending, In Progress, Completed).
🔹 Filtering and sorting to display relevant tasks.
🔹 Real-time updates when tasks are modified.
🔹 Synchronization with backend APIs for persistence.
Traditional state management solutions like NgRx require dispatching actions, writing reducers, and handling effects, adding significant complexity. @ngrx/signalstore simplifies this by allowing you to manage tasks with signals instead of observables.
Let’s break down how @ngrx/signalstore enhances task management with key benefits.
1. Simplified State Management
With @ngrx/signalstore, defining and updating state is straightforward. You no longer need to handle complex reducer functions or boilerplate-heavy selectors. Instead, you define a store and directly modify its signals.
Example:
typescriptCopyEditimport { signalStore, withState } from '@ngrx/signal-store';
interface Task {
id: string;
title: string;
completed: boolean;
}
const TaskStore = signalStore(
{ name: 'tasks' },
withState<{ tasks: Task[] }>({ tasks: [] })
);
This creates a task store where tasks are managed reactively without additional NgRx boilerplate.
2. Fine-Grained Updates
Instead of re-rendering entire lists when a single task changes, signals update only the necessary parts of the state.
Example: Marking a task as complete:
typescriptCopyEditthis.taskStore.update((state) => ({
tasks: state.tasks.map(task =>
task.id === taskId ? { ...task, completed: true } : task
)
}));
This ensures only the modified task updates, boosting performance and efficiency.
3. Automatic Dependency Tracking
With traditional NgRx, updating a single value often requires defining selectors and effects. In contrast, @ngrx/signalstore automatically tracks dependencies.
Example: Filtering tasks dynamically:
typescriptCopyEditimport { computed } from '@angular/core';
const completedTasks = computed(() =>
this.taskStore.tasks().filter(task => task.completed)
);
Here, completedTasks
automatically updates whenever the task list changes, eliminating the need for explicit subscriptions.
4. Minimal Boilerplate for API Integration
If tasks are stored on a backend, @ngrx/signalstore simplifies API interactions. Instead of handling effects manually, signals can be updated directly from API calls.
Example: Fetching tasks from an API:
typescriptCopyEditimport { inject } from '@angular/core';
import { HttpClient } from '@angular/common/http';
const http = inject(HttpClient);
this.taskStore.update(async (state) => {
const tasks = await http.get<Task[]>('/api/tasks').toPromise();
return { ...state, tasks };
});
This makes fetching and updating data cleaner compared to the traditional NgRx effects approach.
How @ngrx/signalstore Transforms Task Management Application
Let’s look at a real-world example where @ngrx/signalstore dramatically simplifies task management.
1. Defining the Store
A simple store to manage task data:
typescriptCopyEditconst TaskStore = signalStore(
{ name: 'tasks' },
withState<{ tasks: Task[]; filter: string }>({ tasks: [], filter: 'all' })
);
This store holds:
- tasks: A list of all tasks.
- filter: A signal to track the current filter (e.g., All, Completed, Pending).
2. Adding New Tasks
To add a new task, update the store state:
typescriptCopyEditthis.taskStore.update((state) => ({
tasks: [...state.tasks, { id: generateId(), title: 'New Task', completed: false }]
}));
This directly modifies the state without dispatching an action.
3. Filtering Tasks Dynamically
Instead of writing selectors, use computed signals:
typescriptCopyEditconst filteredTasks = computed(() =>
this.taskStore.tasks().filter(task =>
this.taskStore.filter() === 'all'
? true
: this.taskStore.filter() === 'completed'
? task.completed
: !task.completed
)
);
Now, the UI automatically updates when the filter changes.
Should You Use @ngrx/signalstore for Task Management?
If you’re building a task management application, @ngrx/signalstore offers a cleaner, faster, and more scalable approach than traditional NgRx.
✅ Use @ngrx/signalstore if:
✔️ You want simplified state management with minimal boilerplate.
✔️ You need high-performance UI updates with fine-grained reactivity.
✔️ Your app frequently modifies state, such as adding, updating, and filtering tasks.
✔️ You want automatic dependency tracking without extra subscriptions.
❌ Avoid @ngrx/signalstore if:
❌ You require complex side effects like heavy async processing.
❌ Your app already uses NgRx extensively, and migrating is costly.
❌ You rely on strict Redux-like patterns for team consistency.
