The providedIn property is used within the @Injectable decorator to specify where the service should be provided. This is a more modern and preferred way to provide services in Angular.
Global Scope: When you use providedIn: 'root', the service is registered with the root injector, making it a singleton and available throughout the entire application.
In Angular, providers are a fundamental concept that allows you to inject dependencies into your components, services, and other parts of your application. They play a crucial role in Angular's dependency injection (DI) system, making it easier to manage and share services across your application.
A provider is an instruction to the Angular dependency injection system on how to obtain a value for a dependency. When you configure a provider, you tell Angular how to create an instance of a service or value that can be injected into components, directives, pipes, or other services.
Lazy loading is a design pattern in Angular that allows you to load modules only when they are needed, rather than loading all modules upfront. This can significantly improve the performance of your application by reducing the initial load time.
A lazy-loaded module is an Angular module that is loaded on demand. Instead of being included in the main bundle, it is loaded asynchronously when the user navigates to a route that requires the module.
Dependency Injection (DI) is a design pattern used to implement IoC (Inversion of Control), allowing a class to receive its dependencies from an external source rather than creating them itself. Angular’s DI system is a powerful feature that makes it easy to manage dependencies and promote code reusability and testability.
In Angular, DI is used to provide components, services, and other classes with the dependencies they need. The Angular injector is responsible for creating and managing these dependencies. Here’s a step-by-step explanation of how DI works in Angular:
In Angular, decorators are used to attach metadata to classes, methods, properties, and parameters. Two commonly used decorators are @Injectable and @Inject. While they might seem similar, they serve different purposes. Let’s dive into their differences and see how they are used with examples.
The @Injectable decorator is used to mark a class as available for dependency injection. It tells Angular's dependency injection system that the class can be injected as a dependency into other classes.
