Angular has grown into an excellent framework over time which is used for the very purpose of developing applications across platforms. With the limited phase of the framework heading to the unlimited phase, you can expect many major features being added to this framework.
Today we will talk about the CLI – Command Line Interface of this framework, its uses to developers in exploiting the resources to the maximum to obtain optimum efficiency in terms of speed and productivity. The main purpose of Angular CLI is to create an application which works with ease.
Angular CLI provides you an option to generate components, routes, services and pipes with a simple command. Numerous things can be achieved with the CLI alone. Some of the noticeable ones are:
You can Install Angular CLI by running below command on your terminal. Make sure Node js and NPM latest version is installed.
npm install -g @angular/cli
Installing Angular is very easy with the ng command. Once you know that the Angular has been installed, you could create a new application in 2 ways:
With either of these 2 steps, your application will be created in the specified directory. You could start running the application once you have added all the necessary features to it.
However, do ensure that you have these 3 things configured or framework will automatically get configured to default values if you don't.
Using the Generate package for Angular, you could add class, component, directives, modules, pipes and new service to your application.
A test runner will automatically start once you create an application. Using the same ng command, you could specify the CLI to create a corresponding file with a sample test for the features added.
These files are created in the same directory of the application. All units can be tested at once using the same ng command with all the files in the source directory.
The command ng server builds and bundles the newly created application to the virtual file system when in the development stage. You need read files which are meant to be deployed to the server or cloud for production.
Once you start with the command ng build, you have these options at your disposal:
Some of the features that you could expect to work within the near future for this Angular CLI would be application support, extensibility, enhanced performance and library developer mode.
The growth in Angular has been exponential; you need to upgrade yourself with the latest trends in the market to provide that out of the box service to your clients.
