vue3 setup

To set up Vue.js 3:

Install Node.js and npm on your machine if they are not already installed.
Open your terminal and run the following command to install the Vue CLI:
```
npm install -g @vue/cli
```
Create a new project using the Vue CLI:
```
vue create my-project
```
Replace "my-project" with the name of your project.
Follow the prompts to configure your project. Choose "default" for the preset.
Once the project is created, navigate to the project directory:
```
cd my-project
```
Start the development server:
```
npm run serve
```
This will start the server at http://localhost:8080. You can now start building your Vue app!
