Angular 12 is the latest version in the Angular family. Angular applications are basically designed for Single Page Applications (SPAs), where all controls are required in single page architecture. Angular is an application-based design framework, which provides the Cross-Platform development environment for creating the most sophisticated SPAs. These SPAs are efficient enough for giving us a component to view the model environment, making it an MVC or MVVM application.
Angular provides a Progressive Web App architecture, which means that an application made in Angular gives us an App like experience with high-performance. Angular has zero-step installation, making its up- gradation using modern web capabilities possible, even if offline. Angular has the capability of making cross platform Desktop Apps. These can be created using MAC, Windows, or Linux OS using the same Angular methods. Angular can be rendered in Node.js, Microsoft .Net, PHP and many other servers by giving the output in HTML-CSS format. This even optimizes the App for SEO. Angular framework turns our templates into JavaScript Virtual machine codes which are highly optimized. With Angular CLI, the Command Line tools, we can build and deploy apps faster than ever before. Angular uses Karma for unit tests and Protractor for scenario tests, making the applications made in Angular more stable.

In this Article we are going to talk about how to install Angular in mac in a step-by-step manner.
What is Angular?
An open-source framework called Angular (Angular 17 latest version) is a potent and popular tool for creating dynamic single-page web applications. Angular provides a set of tools and features that developers can use to create complex and responsive user interfaces.
Angular is based on TypeScript, a superset of JavaScript that adds static typing and other features to improve code clarity and maintainability. It uses a component-based architecture, where applications are built by composing small, independent components that can be reused throughout the application.

Node.js is an open-source software which is used to run JavaScript code outside a browser. Node.js is cross-platform making it suitable for major operating systems. It helps developers to use JavaScript in Network Applications, Command Line Tools, normal Web Applications, Web APIs, and more. It provides Dev Tooling local Web Server for live reloading and development experience. Wondering where to begin your web development career? Enroll in Website Development courses.
Thus, Node.js is an Open-Source Server environment that allows developers to run JavaScript on the server.
So, before installing Angular in mac we need to install Node.js in the System.
Download Node.js
Open the following site in the browser.
(Download the Node.js source code or a pre-built installer for your platform, and start developing today). We get the site as follows:
Download the LTS version of the software with the latest features. This gives us three versions for different operating systems:

Download the macOS Installer (.pkg) : 64-bit (node-v14.15.0.pkg). This is the latest version of Node installable package.
Install the .pkg in your operating system by clicking on the installer. Once clicked, the .pkg file opens the installer wizard. Click on continue to move to the next page.
Click on continue to continue to the next page with License Terms and Conditions. You will be asked to accept the license, please do so by clicking on Agree, after reading the terms and conditions.
Click on Continue to move to the next page.
Once you have clicked on continue, you will get the install now page:
Click on Install, and enter the login credentials, the username and password, and then click on Install Software:
Once successfully installed, Node.js shows the following summary of the installation:
Click on Close to close the wizard.
Set the /usr/local/bin in your $PATH so that you can access the node and npm executable files. To verify the same open the terminal and type:
Echo $PATH
Test Installation of Node.js
Once the package is installed, open the Terminal and type the following command:
node –v
You will get the version of Node.js displayed.
v14.15.0
and
npm –v
You get the version of npm displayed.
6.4.1
Installation of Angular CLI
Angular CLI has a wide range of commands for Angular Applications. It helps us in managing, testing, and building Angular applications.
Once Node.js is installed in our system, we can use npm to install software globally on our system. Use –g option in the npm command to install the Angular CLI tool globally. Once done so it will be accessible to all users and applications on the mac OS system.
To install Angular CLI with the Node.js npm tool, use the following command:
$ sudo npm install -g @angular/cli
This command will install the latest Angular CLI version available at Angular site on your macOS system.
If you require other than the latest version of Angular, then use the following command in your mac OS:
For Angular 6:
$ npm install -g @angular/cli@6#Angular 6
For Angular 7:
$ npm install -g @angular/cli@7 #Angular 7
For Angular 8:
$ npm install -g @angular/cli@8 #Angular 8
For Angular 9:
$ npm install -g @angular/cli@9 #Angular 9
Testing the Installation of Angular CLI
Once the installation is successful, Angular CLI will provide a command ng to be used for command line operations.
Type the following command to check the version of Angular CLI:
$ ng --version
Or
$ ng version
And we should get the following output:
This completes your Angular installation on Mac. Now let us make a “Hello World” Application in Angular. Following section describes how to make a basic application in Angular.
How to Create New Angular Application?
Create a folder for your application in the desired location on your system and open it on your favorite file browser.
A Basic Hello-World Application in Angular
Open a new terminal and move to your folder created for the application and type in the following command to create your app folder using ng create command as below.
$ ng create hello-world
Or
$ ng new hello-world
For the Query “Would you like to add Angular Routing?” type Yes.
For the Query “Which style sheet format would you like to choose?” move your cursor to point to “CSS” and click enter.
Then it would take some time for further installation of the application folder, so we need to have patience in this respect.
At last, when the command is executed successfully, Angular creates a skeleton application under the folder. It also includes a bunch of files and other important necessities for the application.
Serve Angular Application
Once our Hello-World project is created change the current directory to project directory by cd command and run application using ng serve command as shown below:
$ cd hello-world
$ ng serve
We can leave the ng serve command running in the terminal as it will automatically refresh the browser each time we make and save changes in our Angular application. This makes Angular development quick and iterative.
Running the Hello-World Application
Once run, you can access your Angular application on localhost port 4200, which is the default host and port used by any Angular application. To get the output, type in your favorite browser, address bar the following:
http://localhost4200
If another application is running on that address, you can simply run the command.
$ ng serve--port
It will generate a different port for you to navigate to through the web browser.
Check the Output
Typically, the browser looks something like this:

How to Uninstall Angular from macOS?
Step 1: Uninstall Angular CLI
npm uninstall -g @Angular/cli
This will uninstall the Angular CLI globally. It will also remove any globally installed Angular packages, such as @Angular/core and @Angular/compiler.
Step 2: Remove typeScript if installed
npm uninstall -g typescript
Step 3: Delete Angular projects
You will have to delete the projects manually. Navigate to the directories and manually delete them.
cd ~/path/to/your/Angular/project_name
Step 4: Remove npn cache
npm cache clean --force
Step 5: Verify your uninstallation
ng --version
Step 6: Delete the files with configuration settings for Angular.
- ~/.npmrc
- ~/.config/Angular
Step 7: Uninstall NodeJS and npm
If you had installed NodeJS with the sole purpose to run Angular consider uninstalling it.
npm uninstall -g node.
- This will remove the Node.js executable and any globally installed Node.js modules.
- Run the following command to delete the Node.js installation directory:
sudo rm -rf /usr/local/lib/node
How to Use Angular?
- Create a new project using command: ng new my-Angular-app
- Go to your directory using command: cd my-Angular-app
- Create a new component using command: ng generate component my-first-component
This will create a new folder called ‘my-first-component’. - Edit the component template as you wish.
The component template is the HTML code for your component. You can edit the template in the file my-first-component.component.html.
Run your application using the command: ng serve
Some Tricks:
- Angular supports two-way data binding i.e. it allows for automatic synchronization of data between component and template.
- You can use services for fetching the data or business logic. Use the command ng generate service my-service.
- Angular provides a string routing system for building Single Page Applications (SAPs). You can define the routes in app-routing.module.ts file.
- Make sure you utilize the CLI commands like ng generate component, ng generate service, ng test etc. for common tasks.
Conclusion
to start building dynamic and reliable web applications and with this blog hopefully you will be able to install Angular in Mac. Through Angular 12 we can develop very dynamic applications. However, sometimes we may require to undo the installation of Angular CLI.
Angular applications are still SPAs or Single Page Applications in their Core. The loading of the Application is still triggered by a main request to the server. The command ng serve helps us to serve this request every time we make changes to our scripts. As our HTML or JavaScript changes, so does the new server request, sending the new changed response to the web browser.
Equipped with the understanding acquired from this how to install Angular in Mac guide, you are ready to investigate the countless opportunities that Angular presents for developing cutting-edge, feature-rich web applications for the macOS operating system.
