Angular is an open-source, JavaScript framework written in TypeScript. Google maintains it, and its primary purpose is to develop single-page applications. As a framework, Angular has clear advantages while also providing a standard structure for developers on a team to work with. It enables users to develop large applications in a maintainable manner. What is Angular Dependency Injection? Known to be a programming paradigm, Angular dependency injection is what makes a class independent of its dependencies. Angular Dependency injection enables the creation of dependent objects outside of a class while providing those very objects to a class in numerous ways.

In the last lecture we learned that creating an instance of a service by our own is not a good practice. Instead we can ask angular to inject an instance of a service in the component where we want to use it. This is called as dependency injection. Dependency injection is a concept where another source injects a dependency of a class to that class, making the class loosely coupled with dependent class. Let's leran with an example, how we cen inject a dependency to a component in this lecture.

It provides an ecosystem for the development of client-side web applications. The ecosystem for development may include external tools or libraries as well. The ecosystem process includes project bootstrapping, development operations/tools, testing, and build support. One of the best features of Angular framework is that it is quite flexible when it comes to the usage of external libraries apart from the scalability it provides. With Angular framework adoption being high, performance management of the application is community-driven indirectly driving better job opportunities. Got a question on the topic?

Spring Dependency Injection. Practical : 🤍 Spring Full Course : 🤍 Spring Full Course (UDEMY) : 🤍 Angular Full Course : 🤍 In software engineering, dependency injection is a technique whereby one object (or static method) supplies the dependencies of another object. A dependency is an object that can be used (a service). An injection is the passing of a dependency to a dependent object (a client) that would use it. The service is made part of the client's state.[1] Passing the service to the client, rather than allowing a client to build or find the service, is the fundamental requirement of the pattern. -wikipedia Dependency Injection is a design pattern.

In this lecture, you will learn what is heirarchical dependency injection in Angular and how it works? In Angular, angular uses hierarchical dependency injection. That means, when we ask Angular to inject a dependency for a component, the same instance of that dependency get's injected for the child components and their child components as well. Let's understand hierarchical dependency injection with some examples and how heirarchical dependency can be injected in varius places of an Angular App.

Hope you can help. 🤍 Slides 🤍 Angular 2 Tutorial playlist 🤍 Angular 2 Text articles and slides 🤍 All Dot Net and SQL Server Tutorials in English 🤍 All Dot Net and SQL Server Tutorials in Arabic 🤍 In this video we will discuss 1. What is Dependency Injection 2. How dependency injection works in angular Let us understand Dependency Injection in Angular with an example. Consider this piece of code in EmployeeListComponent. export class EmployeeListComponent implements OnInit { private _employeeService: EmployeeService; constructor(_employeeService: EmployeeService) { this._employeeService = _employeeService; } ngOnInit() { this._employeeService.getEmployees() .subscribe( employeesData =] this.employees = employeesData, error =] this.statusMessage = 'Error'); } // Rest of the code } 1. We register a service with the angular injector by using the providers property of 🤍Component decorator or 🤍NgModule decorator. 2. When a component in Angular needs a service instance, it does not explicitly create it. Instead it just specifies it has a dependency on a service and needs an instance of it by including the service as a constructor parameter. 3. When an instance of the component is created, the angular injector creates an instance of the service class and provides it to component constructor. 4. So the component which is dependent on a service instance, receives the instance from an external source rather than creating it itself. This is called Dependency Injection. What is Dependency Injection It's a coding pattern in which a class receives its dependencies from an external source rather than creating them itself. So if we relate this definition to our example, EmployeeListComponent has a dependency on EmployeeService. The EmployeeListComponent receives the dependency instance (i.e EmployeeService instance) from the the external source (i.e the angular injector) rather than creating the instance itself. 1. Why should we use Dependency Injection? 2. What benefits it provide? 3. Why can't we explicitly create an instance of the EmployeeService class using the new keyword and use that instance instead in our EmployeeListComponent? We will answer these questions in our next video.

A typical angular application uses the dependency injection to share functionality inside of the app. A huge benefit of it is that you don't have to copy-paste your functional code over and over again. The Angular injector handles the requests of service for you as long as your components and services are using the 🤍Injectable decorator.

Want to learn Angular? In this video, "Learn Angular: Using Services with Angular 9 Dependency Injection", you'll learn how to use Angular dependency injection to inject services into your Angular components. When creating and using services in an Angular 9 application, it is recommended to utilize dependency injection. Dependency injection is built into the Angular framework and can be implemented by following 3 easy steps. 1. Create a service 2. Decorate the service for injection 3. Inject the service The easiest way to create a service is by sing the Angular CLI. Simply type: ng g s nameOfService There is no need to add the word "Service" at the end of the name of your service. This will be added for you automatcally by the Angular CLI The Angular CLI will automatically decorate the newly created service class with the Injectable decorator. The decorator will provide the value of "root" for the providedIn property. This will instruct angular to register the service for use across the entire application. You can configure your service to be scoped at the component level by removing the providedIn property and adding the service class to the component's providers property array. 🤍Injectable()[{ providedIn: 'root' }] Finally, to use the service, simply request the service via the component's constructor as an argument. constructor(private titleService: TitleService){ } Just like that, you now have services being created and injected into your components for use throughout your Angular application by using dependency injection.

We can configure the DI framework in Angular in three main ways. We can configure a provider on the NgModule, on a component or directives providers property and on a components viewProviders property. Deciding where to configure your provider and understanding the difference is the key to understanding how to architect an Angular application. If we want an instance of a dependency to be shared globally and share state across the application we configure it on the NgModule. If we want a separate instance of a dependency to be shared across each instance of a component and it’s children we configure it on the components providers property. If we want a separate instance of a dependency to be shared across each instance of a component and only it’s view children we configure it on the components viewProviders property.
