Step 1. What is the pre-requesting to install the Angular?
Before installation of Angular, you should install the Node.js and Node package Manager ( npm ). So check the installation of Node.js and npm.
Use below command check the version of Node.js, installed version should be at least 4.0.0.
Use below command to get the version of Node Package Manager (npm) it should be at least 3.0.0
If you are getting node or npm command not found the error, that means Node.js not installed on your machine. So for installation of Node.js and npm check out our earlier tutorial about how to install Node.js on Linux.
For installation of Node.js on windows machine download the Node.js package from Nodejs.org official website and install as like you install the other application on windows.
Step 2. Install the AngularCLI
AngularCLI is the tool to work globally to create the app, install the dependency, to run the test HTTP server, etc. When you create the app using AngularCLI directory structure of your project will be created by default along with the configuration of testing environment like Karma. So use the below command to install the Angular CLI.
For installation of Angular CLI on windows you can use the same command by just removing the sudo.
Step 3. Create the first Angular App
For creating the Angular app to test your installation use the below command from a terminal. We can use the same command in Linux as well as Windows.
Above command will take some time and create the directory structure as well as install any missing dependency. The output of the above command will look like as given below.
you can check the directory structure of your project by moving to the myfirstapp folder which was created by ng new command.
Step 4. Start the HTTP server and test your first project
Installation of the Angular are completed, we have created our first angular app in above steps now it's time to test the whole thing. So for testing, we can start the server using the below command by moving to your project folder.
Step 5. Open the browser and test the output
So by pointing your browser at address http://localhost:4200 you will get the output for which we are here " app Works".
Installation and testing of Angular have been completed. If you have any further queries or question on this feels free to post your comment below.
Step 6. Update Angular CLI Version
