Part 3 Angular Tutorial | Angular components creation | Component directive | Ng Module
In Angular, a component is a building block of the application's user interface. A component consists of three parts: a TypeScript file, an HTML file, and a CSS file. Here are the steps to create a new component in Angular:
Open your terminal or command prompt and navigate to the directory where you want to create the component.
Use the Angular CLI (Command Line Interface) to generate a new component by running the command ng generate component component-name. This will create a new directory with the given component name, and inside the directory, you will find the TypeScript, HTML, and CSS files for the component.
For example, to create a new component called navbar, run the following command:
Copy code
ng generate component navbar
After running the above command, the Angular CLI will create the necessary files and update the application's file structure. You can now find the new component in the app directory under src.
Open the navbar.component.ts file and add any necessary properties and methods for the component. The TypeScript file is where you define the component's behavior and interactions.
Open the navbar.component.html file and add the HTML code for the component's user interface. The HTML file is where you define the layout and content of the component.
Open the navbar.component.css file and add any necessary styles for the component. The CSS file is where you define the visual appearance of the component.
Finally, you need to add the newly created component to the app.module.ts file. Open the app.module.ts file and import the component at the top of the file. Then, add the component to the declarations array.
Here is an example of how to import and declare the navbar component in the app.module.ts file:
