Prerequisites
Before getting started with this, there are some prerequisites that you must have:
- Basic knowledge of HTML, CSS, and JavaScript.
- Node.js installed on your Operating System.
Verify the Vue CLI installation
First of all, make sure that you have the latest Vue CLI installed on your system. You can verify either Vue CLI is installed or not on our system by typing the command given below:
$ vue --version
If it is installed, you will have the latest version of Vue CLI printed out in the terminal. Otherwise, if it is not installed, you can either use the NPM package manager or Yarn package manager to install the Vue CLI. In order to install it using the NPM package manager, you need to type the command given below in the terminal:
$ npm install -g @vue/cliIn the above command, the -g flag is used for installing Vue CLI globally on your system.
Once the Vue CLI is completely installed, you can verify it by typing the command given below:
$ vue --version
You will have the latest version of Vue CLI in the output.
Project Creation
Now, suppose you are going to set up the whole Vue project on your own. In that case, it is not a good choice to reinvent the wheel; the Vue project can be created using the vue command in the terminal because the Vue CLI provides the already generated templates to start with the Vue project.
To create the Vue application, simply type the command given below in the terminal:
$ vue create project-nameMake sure to replace the project-name with your desired project name and hit Enter.
After a couple of seconds, it will prompt selecting the default preset or selecting some features manually.
If you want to have some custom features, select “Manually select features,” hit Enter, and you will be prompted with some options like selecting the Vue version, adding Vuex, or Router. Select your desired option and hit Enter.
Answer some necessary configuration questions and save the preset for future projects.
The Vue project will be created in a while using the Vue CLI, and you can start the development in Vue.js.
Starting the Vue application
Once the Vue project is created, you can start the project by first navigating to the project's directory using the cd command in the terminal:
$ cd project-nameIn the project's directory, start the Vue application by typing the command given below in the terminal:
$ npm run serveAfter the ignition of the Vue application, visit the http://localhost:8080 in the address bar of your favorite browser:

For example, if we want to import it into the App.vue, the syntax would be like this: After completing all this setup, save each and every file that you have changed and go back to the browser You can witness in the screenshot attached that the component is imported successfully and perfectly fine on the web page.
