SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Angular DI can become tangled without clear patterns; this guide explains how to implement and manage dependency injection in Angular v20+ using inject(), tokens, and providers to improve modularity, testability, and maintainability.

Core Features & Use Cases

  • Inject dependencies with inject() for simpler, testable code.
  • Create and configure InjectionTokens to provide values and configurations.
  • Manage provider scopes (root, component, route) and hierarchical injection across trees.

Quick Start

Start by creating a token for a service and injecting it into a component using inject() to obtain its instance.

Frequently Asked Questions about angular-di

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I use inject() for dependency injection in Angular?▼

The inject() function retrieves service instances directly within components or services, replacing constructor-based Angular dependency injection to produce simpler and more testable code.

What are InjectionTokens and how do they configure providers in Angular?▼

InjectionTokens in Angular create custom tokens to provide specific values and configurations, allowing you to configure provider scopes and decouple dependency injection from concrete class implementations.

How do I manage provider scopes and hierarchical injection across Angular components?▼

Manage Angular provider scopes by configuring root, component, or route-level providers, enabling hierarchical dependency injection that shares instances across component and route trees based on scope.

Does this Angular dependency injection guide cover multi-provider and environment injection patterns?▼

Yes, this dependency injection guide covers multi-provider patterns and environment injection, detailing how to configure multiple providers and manage hierarchical injection across view trees in Angular v20+.

When should I use hierarchical dependency injection in Angular applications?▼

Use hierarchical dependency injection in Angular when building scalable service architectures that require different provider configurations across components, routes, and view trees to improve modularity and maintainability.
