Angular CLI commands for developers using npm

Introduction:

The Angular CLI is an essential tool for developers looking to create Angular projects quickly and efficiently. Let's explore the most useful commands of the Angular CLI, which will help you save time and effort in setting up and building complex projects.

Overview of Angular CLI Commands:

  • 'ng new <project-name>': Creates a new Angular workspace with the specified name. This is the first step when starting a new project.

  • 'ng serve': Compiles and starts the development server. The application is automatically reloaded when there are code changes, making development and testing easier during the build process.

  • 'ng build': Compiles the application and generates output files in the dist/ directory as specified. This command is used to prepare the application for deployment in a production environment.

  • 'ng test': Runs unit tests in the project. It is a best practice to regularly test the code to ensure its quality and prevent regressions.
  • 'ng e2e': Compiles the application, starts the server, and runs end-to-end tests. These tests help verify the overall behavior of the application and ensure that components integrate correctly.

  • 'ng generate <schematic> <component-name>': Automatically generates a new component, directive, pipe, service, class, interface, enum, module, or guard using a predefined schematic. This feature saves time when creating new elements for the application.

  • 'ng add <package-name>':  Adds support for an external library to the project. This feature makes it easy to include additional features and functionalities in the application.

  • 'ng update': Updates the workspace and its dependencies. Keeping Angular and its dependencies up-to-date is important to obtain the latest features and bug fixes.

  • 'ng lint': Runs linting tools on the Angular application code in a project folder. This helps identify syntax errors, style issues, and other problems in the code.

  • 'ng doc <keyword>': Opens the official Angular documentation (angular.io) in a browser and performs a search for the specified keyword. This feature facilitates quick access to Angular documentation during development. 

How to run an Angular CLI command:

To execute any Angular CLI command, simply open a terminal in the project folder and type the desired command. If you need more information about a specific command, type ng help <command> in the terminal.

Conclusion:

The Angular CLI provides a wide range of powerful commands that streamline the development process for Angular projects. Through these commands, you can easily create, test, build, and update your application. Remember to explore the official Angular CLI documentation for more detailed information about each command. With Angular CLI by your side, you'll be on the right path to efficiently develop amazing applications.

templateUrl in Angular: Detailed Explanation

Image
Definition: "templateUrl" is a property of an Angular component that defines the relative path or absolute URL of an external template file for that component. You should not use "templateUrl" together with the template property, which provides an inline template for the component." Syntax: Purpose and Usage:     -  Purpose: Separation of concerns and reusability. Externalizing the template to a separate file enhances code organization and makes it easier to manage, especially for larger applications.     -  Usage: Specify the  property within the  decorator, providing the path to the external template file. "templateUrl" "@Component" Example: Assume you have an Angular component named  and want to use an external template file for it. ExampleComponent example.component.ts: example.component.html: When to Use:     -  Use  when your component's template is more extensive and maintaining it within the component file becomes unwie

Getting Started with Standalone Components in Angular

Image
Introduction: "standalone" components in Angular offer a simplified approach to building applications by reducing reliance on "NgModules" . This approach includes standalone components, directives, and pipes that streamline the authoring experience. It enables existing applications to gradually and optionally transition to this new style without introducing breaking changes. Example Standalone Component: Let's delve into a practical example of a standalone component: Explanation:     -  selector: Specifies the HTML selector for the component (ngbd-table-complete).     -  standalone: true: Marks this component as a standalone component, signaling its independence from NgModules .     -  imports: Lists the modules and components used within this standalone component (DecimalPipe, FormsModule, AsyncPipe, etc.).     -  templateUrl: Points to the external HTML template file for the component (./table-complete.html).     -  providers: Declares the servic

template in Angular: In-Depth Explanation with Examples

Image
Definition: The "template" property is used in Angular components to define an inline template directly within the component metadata. If template is provided, you should not also supply an external template file using the "templateUrl" property. Syntax: Purpose and Usage:     -  Purpose: Convenient for smaller components or when the template is simple and can be easily maintained within the component file.     -  Usage: Include the template property within the @Component decorator, providing the inline HTML   "template" . Example: Assume you have an Angular component named "ExampleComponent" and want to use an inline "template" for it. In this example, the "template" is directly embedded within the @Component decorator. The "{{ name }}" syntax is Angular's interpolation syntax, allowing dynamic content insertion. When to Use:     -  Use template when your component's template is relatively simpl
