Angular Setup & Installation
Setting up an Angular development environment involves several steps, including installing Node.js and the Angular CLI, creating a new Angular project, and running the project in a development server. Here are the details of each step:
Install Angular CLI:
The Angular CLI (Command Line Interface) is a powerful tool that makes it easy to create, manage, and build Angular projects. You can install the Angular CLI using npm, which is the package manager that comes with Node.js. Open a command prompt or terminal and run the following command:
npm install -g @angular/cli
This will install the Angular CLI globally on your computer.
Create a new Angular project:
Once you have installed the Angular CLI, you can create a new Angular project by running the following command in your command prompt or terminal:
ng new my-app
Replace "my-app" with the name of your project. This will create a new Angular project called "my-app" in a new directory.
Run the application:
After creating a new project, you can start the development server and run your application. To do this, navigate to your project folder and run the following command:
This will start a development server and serve your Angular application on
By default, the development server will watch your files for changes and automatically reload the page when changes are detected. This makes it easy to develop and test your application in real-time.
Open the application: With the development server running, you can open your application in a web browser by navigating to http://localhost:4200/. You should see the default Angular welcome page.
Build the application:
Once you are ready to deploy your application, you can build the application using the following command:
This will create a production-ready version of your Angular application in the
In summary, setting up an Angular development environment involves installing Node.js, installing the Angular CLI, creating a new Angular project, serving the application, and building the application. By following these steps, you can start building powerful and dynamic Angular applications.
That's it! You now have a fully functional Angular application set up and running on your computer. From here, you can start making changes to your application and building your own Angular components, services, and directives.
